How to change the address of region "RAM" in BL31?

by Chenxu Wang

Hi all, I want to add some big data structures in BL31 (e.g., create a large uint32_t array). Also, I reserve a secure memory space (assume it is 0xa000_0000 - 0xb000_0000) by configuring TZASC. Now, the BL31 says build/fvp/debug/bl31/bl31.elf section `.bss' will not fit in region `RAM' aarch64-none-elf-ld: BL31 image has exceeded its limit. aarch64-none-elf-ld: region `RAM' overflowed by 458752 bytes It looks like that the previous RAM cannot hold my big data structures. If I want to add my reserved region into RAM (so I may allocate these data into the reserved region), what should I do? Sincerely, Wang

Re: [TF-A] [TF-M] Tip on cloning TF-M on OS X Monterey

by Gyorgy Szing

Hi, Please allow me to add some more details. Also posting to the TF-A list, as all tf.org repositories are affected. The root cause of this issue is OpenSSH dropping support for SHA-1 RSA signatures with the 8.8 release, and thus any OS (or git client) coming with a recent version is affected. I.e. the newest git for windows is affected too, and so are “top notch” Linux distributions like Arch. For details see the “Potentially-incompatible changes” chapter here: https://www.openssh.com/releasenotes.html As the above page states “Incompatibility is more likely when connecting to older SSH implementations…”, and thus a server-side update would eliminate the problem. Till that happens the page above list multiple client-side workarounds. (It is possible to amend the ssh config in a way that fixes all repositories.) /George From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org> On Behalf Of Kevin Townsend via TF-M Sent: December 15, 2021 13:06 To: Thomas Törnblom via TF-M <tf-m(a)lists.trustedfirmware.org> Subject: [TF-M] Tip on cloning TF-M on OS X Monterey I recently switched to a new MBP that ships with OS X Monterey, and on both 12.0 and 12.1 (released this week) git clone seems to be broken when you're using HTTP rather than SSH: digital envelope routines:CRYPTO_internal:bad key length In order to clone TF-M, I had to make the following changes. 1. Add these details to $HOME/.ssh/config (microbuilder being my github username, associated with my TF-M account): Host trustedfirmware.org<http://trustedfirmware.org> User microbuilder Hostname review.trustedfirmware.org<http://review.trustedfirmware.org> Port 29418 IdentityFile ~/.ssh/id_rsa IdentitiesOnly yes 2. Then try to clone with: $ git clone trustedfirmware.org:/TF-M/trusted-firmware-m.git This fails, however, since it tries to clone tf-m-tests.git, so: 3. Edit lib/ext/tf-m-tests/fetch_repo.cmake, changing: FetchContent_Declare(tfm_test_repo GIT_REPOSITORY trustedfirmware.org:TF-M/tf-m-tests.git # GIT_REPOSITORY https://git.trustedfirmware.org/TF-M/tf-m-tests.git GIT_TAG ${TFM_TEST_REPO_VERSION} GIT_PROGRESS TRUE ) This let me at least clone TF-M until the issues with HTTP-based cloning are fixed. Hope this is useful to someone else working on OS X natively. Kevin

FCONF warning for TOS_FW_CONFIG

by Yann Gautier

Hi, On STM32MP1, we'd like BL2 to be agnostic of what BL32 is in the FIP. It can be either OP-TEE or TF-A SP_min. But on STM32MP1, SP_min needs a device tree file (TOS_FW_CONFIG_ID), whereas OP-TEE doesn't use this separate DT image. As TOS_FW_CONFIG_ID is in list of images to be loaded by BL2, we then have a warning message in case OP-TEE is used: WARNING: FCONF: Invalid config id 26 I'd like to silence this warning with this kind of patch: diff --git a/lib/fconf/fconf_dyn_cfg_getter.c b/lib/fconf/fconf_dyn_cfg_getter.c index 25dd7f9eda..f7e9834c3b 100644 --- a/lib/fconf/fconf_dyn_cfg_getter.c +++ b/lib/fconf/fconf_dyn_cfg_getter.c @@ -51,7 +51,11 @@ struct dyn_cfg_dtb_info_t *dyn_cfg_dtb_info_getter(unsigned int config_id) } } - WARN("FCONF: Invalid config id %u\n", config_id); + if (config_id == TOS_FW_CONFIG_ID) { + VERBOSE("FCONF: No TOS_FW_CONFIG image\n"); + } else { + WARN("FCONF: Invalid config id %u\n", config_id); + } return NULL; } I can change the VERBOSE message to INFO. Do you think it is OK if I push the patch? Thanks, Yann

How to load some images in BL31?

by Chenxu Wang

Hi all, I want to load a specific image in BL31. But when I call load_auth_image(). It says "in function `load_image': trusted-firmware-a/common/bl_common.c:87: undefined reference to `plat_get_image_source'" Also, the io_read, io_size and etc. are undefined reference. I find other BL files (bl1, bl2) will call the load_auth_image() in their main functions or sub-functions. If I want to implement it on BL31, what should I do? Should I modify the Makefile? Sincerely, Wang

Linux as BL33
