Adding support for phyCORE AM62L in TF-A

by Florijan Plohl

Hello! We’d like to add support in TF-A for the PHYTEC phyCORE AM62L. On this board we need BL1 to read the on-board EEPROM via I2C to set the correct DRAM timings. Right now we have it working by editing the TI AM62L files on TI's TF-A fork and adding the EEPROM and I2C drivers. Our questions are: - Should we create a separate board for phyCORE AM62L, or would it make more sense to include this as an option in the TI AM62L support? - How much abstraction should we implement for EEPROM and I2C drivers? Thanks for any advice! Best regards, Florijan Plohl

Raspberry Pi-5 platform maintainer

by Manish Pandey2

Hi, I’m looking for details on the Raspberry Pi 5 (RPi5) platform port in TF-A and to identify a potential platform owner/maintainer. I can see an RPi5 port attributed to @mariobalanica02@gmail.com<mailto:mariobalanica02@gmail.com>, but [1] doesn’t list a platform owner for this target. I also haven’t found TF-A documentation describing the software stack or the current level of testing for RPi5. Could someone please point me to: The current platform owner/maintainer, design/bring-up notes around SW stack or testing? [1] : https://git.trustedfirmware.org/plugins/gitiles/TF-A/trusted-firmware-a.git… Thanks Manish

Does FVP_Base_RevC-2xAEMvA platform model has a full support for address translation at PL2 stage-1 MMU in aarch32?

by Marek

Have you ever succeeded in performing a Stage-1 MMU translation using LPAE (Long Physical Address Extension) on the FVP_Base_RevC-2xAEMvA platform model running in AArch32 Hyp mode (CONFIG64=0) into any other Memory but Strongly-Ordered? My environment is - FVP_Base_RevC-2xAEMvA booting SW stack from bullet point below - SW stack from Yocto, 'meta-arm'. I use 'fvp-base-arm32' that builds bl1, bl2, bl32, bl33, Linux kernel and rootfs. The only component that works there at PL2 HYP mode is u-boot (bl33). Whichever attributes I assign there Normal Memory with Inner or Outer Cacheability, Write-Through, or Write-Back, or Non-cacheable I always end up with Strongly-Ordered. To me it looks like it doesn't read the MAIR correctly and/or ignores the Cachability in HCTR. I inspected the MMU code thoroughly there, compared with the other codes for MMU, from trusted-firmware-a, xen, and Linux kernel and it seems u-boot does it correct. U-boot sets there identity-mapping for all 4GB with 0GB through 2GB Strongly-Ordered, 3G - 4G Normal Memory, Cachable Write-Back Write-Allocate, Non-Shareable and the last 1GB also Strongly-Ordered. Here is a brief execution steps it goes through: #1 Sets up the 2M-block at the 2nd level table with attributes. - sample block descriptor for translating from 0x8000_0000 virt to phys: 0x8000044d - bits[1:0] = 0b01 -> valid descriptor, descriptor type: block - bits[4:2] = 0b011 -> AttrIndx[2:0] points to MAIR0[3] . MAIR0[3] is 0xff - bits[5] = 0b0 - Non-secure - bits[7:6] = 0b01 - Access Permission: Read/write - bits[9:8] = 0b00 -> Shareability: non-shareable #2 Sets up 1st level table descriptor pointing to the descriptor shown above. It sets bits[1:0] to 0b11 meaning it is a table descriptor and valid. #3 Set control registers as follows HTCR is: 0x80000500 so - bits[9:8] = 0b01 -> Inner Cacheability to Normal memory, Outer Write-Back Write-Allocate Cacheable - bits[11:10] = 0b01 -> Outer Cacheability to Normal memory, Outer Write-Back Write-Allocate Cacheable - bits[13:12] = 0b00 -> Non-shareable HTTBR is: 0x00000000feff4000 -> points to 1st lavel table set in #2 HMAIR0 is: 0xffeeaa00 -> as shown above AttrIndx[2:0] points to MAIR0 and the four nibble being 0xff. 0xff is Normal memory, Inner Write-Back Cacheablea, Non-transientb HMAIR1 is: 0x00000000 - I set it to zero there as not used. #4 Finally it sets the M and C bits in HSCTLR registers Inspecting the page tables with amrds the region 3GB through 4GB that should be Normal and Cachable is Strongly-Ordered - 0x80000000 | L2 Block | NP:0x0000000080000000 | XN=0, PXN=0, Contiguous=0, nG=0, AF=1, SH=0x0, AP=0x1, AttrIndx=0x3 - H:0x80000000-0xFEFFFFFF | NP:0x80000000-0xFEFFFFFF | Strongly-ordered | NA | False | True | True Least not last are the parameters I pass to the model: FVP_Base_RevC-2xAEMvA --parameter bp.ve_sysregs.exit_on_shutdown=1 --parameter bp.virtio_net.enabled=1 --parameter bp.virtio_net.hostbridge.userNetworking=1 --parameter bp.virtio_net.hostbridge.userNetPorts=8022=22 --parameter cache_state_modelled=0 --parameter bp.secureflashloader.fname=/home/ubuntu/yocto/poky/arm32-aem-build/tmp/deploy/images/fvp-base-arm32/bl1-fvp.bin --parameter bp.flashloader0.fname=/home/ubuntu/yocto/poky/arm32-aem-build/tmp/deploy/images/fvp-base-arm32/fip-fvp.bin --parameter bp.virtioblockdevice.image_path=/home/ubuntu/yocto/poky/arm32-aem-build/tmp/deploy/images/fvp-base-arm32/core-image-minimal-fvp-base-arm32-20250630100348.rootfs.wic --parameter cluster0.has_arm_v8-4=1 --parameter cluster1.has_arm_v8-4=1 --parameter cluster0.cpu0.CONFIG64=0 --parameter cluster0.cpu1.CONFIG64=0 --parameter cluster0.cpu2.CONFIG64=0 --parameter cluster0.cpu3.CONFIG64=0 --parameter cluster1.cpu0.CONFIG64=0 --parameter cluster1.cpu1.CONFIG64=0 --parameter cluster1.cpu2.CONFIG64=0 --parameter cluster1.cpu3.CONFIG64=0 --data cluster0.cpu0=/home/ubuntu/yocto/poky/arm32-aem-build/tmp/deploy/images/fvp-base-arm32/zImage@0x80080000 --data cluster0.cpu0=/home/ubuntu/yocto/poky/arm32-aem-build/tmp/deploy/images/fvp-base-arm32/fvp-base-revc.dtb@0x8fc00000 --parameter 'bp.terminal_0.terminal_command=tmux new-window -n "%title" "telnet localhost %port"' --parameter bp.terminal_1.start_telnet=0 --parameter bp.terminal_2.start_telnet=0 --parameter bp.terminal_3.start_telnet=0 --iris-server --iris-port 7102 --iris-allow-remote And an interrupted (not full for longevity) console log: NOTICE: Booting Trusted Firmware NOTICE: BL1: v2.8(debug):dd37aa5be-dirty NOTICE: BL1: Built : 20:04:50, Aug 4 2025 NOTICE: BL1: Booting BL2 NOTICE: BL2: v2.8(debug):dd37aa5be-dirty NOTICE: BL2: Built : 20:04:50, Aug 4 2025 NOTICE: BL1: Booting BL32 WARNING: FCONF: Invalid config id 26 INFO: SP_MIN FCONF: HW_CONFIG address = 0x7f00000 INFO: FCONF: Reading HW_CONFIG firmware configuration file from: 0x7f00000 INFO: FCONF: Reading firmware configuration information for: cpu_timer INFO: FCONF: Reading firmware configuration information for: uart_config INFO: FCONF: Reading firmware configuration information for: topology INFO: FCONF: Reading firmware configuration information for: gicv3_config NOTICE: SP_MIN: v2.8(debug):dd37aa5be-dirty NOTICE: SP_MIN: Built : 20:04:50, Aug 4 2025 U-Boot 2022.04 (Aug 06 2025 - 16:41:21 +0000) vexpress_aemv8a fvp aarch32 DRAM: 2 GiB WARNING: Caches not enabled Core: 2 devices, 2 uclasses Flash: 64 MiB MMC: Loading Environment from nowhere...

optee_ftpm + ms-tpm-20-ref support for RSA key sizes 3072 or 4096 causes a panic

by Dennis Kong

Dear community: I apologize in advance if this is the incorrect place to solicit for input on an issue I am having when enabling support of RSA key sizes > 2048. The environment is described below: TI AM642-EVM board Debian Bookworm running kernel 6.6.100, tpm_ftpm_tee.ko kernel module Uboot booting from sdcard UEFI partition and rootfs partition optee_os version 4.5.0 , 4.6.0, 4.7.0 (no difference in behaviour) optee_client version 4.5.0, 4.6.0, 4.7.0 (no difference in behaviour) optee_ftpm version 4.5.0 or 4.6.0, 4.7.0 (no difference in behaviour) ms-tpm-20-ref commit id 98b60a44aba79b15fcce1c0d1e46cf5918400f6a and e9fc7b89d865536c46deb63f9c7d0121a3ded49c Due to issues with RPMB, we decided to use REE_FS instead. Everything works correctly when I create RSA 2048 keys using tpm2-openssl and related tools: sudo tpm2_createprimary -C o -G rsa2048 -g sha256 -c primary.ctx, When I try rsa3072 or 4096, I get errors from the command line response saying invalid input parameters. I changed the ms-tpm-20-ref include file TpmProfile.h to set RSA_3072 and RSA_4096 macros both to (ALG_RSA && YES). After rebuilding and running, I now get an optee panic for ANY RSA key request INCLUDING rsa2048. I read suggestions to increase the MAX_COMMAND_SIZE/MAX_RESPONSE_SIZE on both the kernel driver tpm_ftpm_tee.ko and also optee_os/optee_ftpm, as well to increase relevant TA_STACK_SIZE and TA_HEAP_SIZE and TA_DATA_SIZE, but nothing seems to change the panic output: sudo tpm2_createprimary -C o -G rsa2048 -g sha256 -c primary.ctx============================================================ E/TC:? 0 E/TC:? 0 TA panicked with code 0xffff0007 E/LD: Status of TA bc50d971-d4c9-42c4-82cb-343fb7f37896 E/LD: arch: aarch64 E/LD: region 0: va 0x40005000 pa 0x9e8b0000 size 0x002000 flags rw-s (ldelf) E/LD: region 1: va 0x40007000 pa 0x9e8b2000 size 0x008000 flags r-xs (ldelf) E/LD: region 2: va 0x4000f000 pa 0x9e8ba000 size 0x001000 flags rw-s (ldelf) E/LD: region 3: va 0x40010000 pa 0x9e8bb000 size 0x004000 flags rw-s (ldelf) E/LD: region 4: va 0x40014000 pa 0x9e8bf000 size 0x001000 flags r--s E/LD: region 5: va 0x40015000 pa 0x9e934000 size 0x011000 flags rw-s (stack) E/LD: region 6: va 0x40026000 pa 0x8ebf0000 size 0x002000 flags rw-- (param) E/LD: region 7: va 0x4006e000 pa 0x9e8c0000 size 0x058000 flags r-xs [0] E/LD: region 8: va 0x400c6000 pa 0x9e918000 size 0x01c000 flags rw-s [0] E/LD: [0] bc50d971-d4c9-42c4-82cb-343fb7f37896 @ 0x4006e000 E/LD: Call stack: E/LD: 0x4006f394 E/LD: 0x40095edc E/LD: 0x4007b5a8 E/LD: 0x400985fc E/LD: 0x40098a70 E/LD: 0x4006fae0 E/LD: 0x400a5508 E/LD: 0x40098b9c D/TC:? 0 user_ta_enter:195 tee_user_ta_enter: TA panicked with code 0xffff0007 D/TC:? 0 release_ta_ctx:670 Releasing panicked TA ctx D/TC:? 0 tee_ta_invoke_command:798 Error: ffff3024 of 3 [ 218.944680] tpm tpm0: ftpm_tee_tpm_op_send: SUBMIT_COMMAND invoke error: 0xffff3024 [ 218.952379] tpm tpm0: tpm_try_transmit: send(): error -53212 D/TC:? 0 tee_ta_invoke_command:798 Error: ffff3024 of 3 [ 218.963359] tpm tpm0: ftpm_tee_tpm_op_send: SUBMIT_COMMAND invoke error: 0xffff3024 [ 218.974241] tpm tpm0: tpm_try_transmit: send(): error -53212 D/TC:? 0 tee_ta_invoke_command:798 Error: ffff3024 of 3 [ 218.985675] tpm tpm0: ftpm_tee_tpm_op_send: SUBMIT_COMMAND invoke error: 0xffff3024 [ 218.993366] tpm tpm0: tpm_try_transmit: send(): error -53212 [ 218.999044] tpm tpm0: tpm2_commit_space: error -14 ERROR:tcti:src/tss2-tcti/tcti-device.c:198:tcti_device_receive()D/TC:? 0 tee_ta_invoke_command:798 Error: ffff3024 of 3 Failed to get response size fd 3, got errno 14: Bad address E[ 219.015351] tpm tpm0: ftpm_tee_tpm_op_send: SUBMIT_COMMAND invoke error: 0xffff3024 RROR:esys:src/tss2-esys/api/Esys_CreatePrimary.c:404:Esys_Create[ 219.028348] tpm tpm0: tpm_try_transmit: send(): error -53212 Primary_Finish() Received a non-TPM Error ERROR:esys:src/tss2-esys/api/Esys_CreatePrimary.c:135:Esys_CreatePrimary() Esys Finish ErrorCode (0x000a000a) ERROR: Esys_CreatePrimary(0xA000A) - tcti:IO failure ERROR:esys:src/tss2-esys/esys_iutil.c:1145:iesys_check_sequence_async() Esys called in bad sequence.

The issue I have is kernel 6.6.100's tpm_ftpm_tee ignores the "memory-region" dts statement that references the optee_shm reserved memory at at 0xa4000000 in my case. Below is my snippet of the dts file. I heard there are patches in the kernel ftpm driver to support the reserved shared memory, but before I try the patches, can anyone opine whether this could cause the panic that I am seeing? Thanks in advance for anyone who can share any information optee_shm: optee-shm@a4000000 { compatible = "shared-dma-pool"; reg = <0x0 0xa4000000 0x0 0x01000000>; no-map; reusable; }; .... firmware { optee { compatible = "linaro,optee-tz"; method = "smc"; memory-region = <&optee_shm>; }; } Dennis Kong, P.Eng.

Does spmd_group0_interrupt_handler_nwd() need to take into account handling of special INTIDs?

by YANG Jun

Hi there, Do spmd_group0_interrupt_handler_nwd() and spmd_handle_group0_intr_swd() need to take into account handling of special INTIDs? Like ehf_el3_interrupt_handler(): /* * Acknowledge interrupt. Proceed with handling only for valid interrupt * IDs. This situation may arise because of Interrupt Management * Framework identifying an EL3 interrupt, but before it's been * acknowledged here, the interrupt was either deasserted, or there was * a higher-priority interrupt of another type. */ intr_raw = plat_ic_acknowledge_interrupt(); intr = plat_ic_get_interrupt_id(intr_raw); if (intr == INTR_ID_UNAVAILABLE) return 0; Best Regards, Joe Yang

Contributing to Trusted Firmware Armv7-A and Armv8-A

by Waqas Mazhar

Hi all, Hope you are well. I have recently joined this mailing list and am quite keen to contribute to this project but don't know where to start. Currently, I am going through Trusted Firmware A Documentation <https://trustedfirmware-a.readthedocs.io/en/latest/index.html> document and Gerrit code reviews <https://review.trustedfirmware.org/q/status:open+-is:wip> to develop some initial understanding and familiarity about the project. As a first step, I am trying to understand areas where I can contribute. Is there any simple issue for me to pick? I am happy to volunteer. Looking forward to hearing from you, Waqas

MISRA Compliance: Request to consider filing deviation for 11.1 (Function Pointer Conversions) in TF-A

by Dhruva Gole

Hello, Background & Justification: MISRA C:2012 Rule 11.1 forbids the conversion from a function pointer to any other type. However, in the context of TF-A, we encounter scenarios where this conversion is necessary and performed with full knowledge of the target architecture and toolchain behavior. A prominent example is in low-level platform code, such as transferring control between bootloader stages or passing function entry points for CPU/core bring-up, where the conversion is unavoidable and well-understood. One such example is the K3 PSCI driver [1] where we pass the k3_sec_entrypoint which is of type uintptr_t, to the ti_sci_proc_set_boot_cfg function where the parameter is of type uint64_t. Another place that triggered the discussions behind this MISRA C issue was the TI AM62L PSCI driver [2] that needs a 16b aligned function pointer. We don't have to go into specific case by case discussion of solving these issues, but just wanted to share example use cases of function pointer conversion. Request: I propose we formally document a project-wide MISRA C:2012 Rule 11.1 deviation, reflecting current and future usage throughout the TF-A codebase. This deviation allows us to balance MISRA objectives with the practical and architectural necessities of TF-A development. Rationale: * Conversions between function pointers and other types are essential in several parts of the TF-A codebase, not limited to one module or file. * Platform-specific code (e.g., power management, bootloader hand-offs) relies on this pattern for correct operation. References: [1] https://github.com/ARM-software/arm-trusted-firmware/blob/master/plat/ti/k3… [2] https://github.com/ARM-software/arm-trusted-firmware/blob/master/plat/ti/k3… -- Best regards, Dhruva Gole Texas Instruments Incorporated

Context uninitialized assertion failure in xlat_tables_core for ZynqMP

Hello, I want to boot Linux on ZynqMP (XCZU15EG). I follow the standard procedure. I have generated FSBL using Vitis. I have compiled bl31 (tag: xilinx-v2025.1). I have a standard boot.bif configuration looking as follows: the_ROM_image: { [bootloader] fsbl.elf [pmufw_image] pmufw.elf [destination_cpu = a53-0, exception_level= el-3, trustzone] bl31.bin [destination_cpu = a53-0, exception_level= el-2, load = 0x10000000] images/u-boot.bin } However, the bl31 reports the following error during the handoff to u-boot: ASSERT: lib/xlat_tables_v2/xlat_tables_core.c:788 BACKTRACE: START: assert 0: F_FUNCTION: 0x2880 1: F_FUNCTION: 0x4cac 2: F_FUNCTION: 0x2628 3: F_FUNCTION: 0x36e0 4: F_FUNCTION: 0x108 5: F_FUNCTION: 0xfffcd8e8 BACKTRACE: END: assert This is an assertion for context being uninitialized in the mmap_add_region_ctx function. /* Static regions must be added before initializing the xlat tables. */ assert(!ctx->initialized); Does anyone have any idea what might be wrong?
