Hello, I got problems here:

I built the whole system with yotcto 3.3.3, linux kernel 5.10, optee-os 3.14, platform for rk3399 ( was working for qemu platform ).

Console Configuration: U-Boot / TrustFirmware-A / optee-os: all pointed console to uart2 linux dts: chosen and secure-chosen all pointed to uart2. uart2's status and secure-status are both set to "okay"

Build Configuration: optee-os:

DEBUG=1 \ CFG_TEE_CORE_LOG_LEVEL=4 \ CFG_TEE_CORE_DEBUG=y \ CFG_TEE_TA_LOG_LEVEL=4 \ ...

both optee-examples and my TA:

DEBUG=1 \ CFG_TEE_TA_LOG_LEVEL=4 \ ...

During boot I can see D/TC: logs, but no any D/TA: log is output.

Some D/TC log like this:

D/TC:? 0 tee_ta_init_session_with_context:607 Re-open TA xxxxx D/TC:? 0 tee_ta_close_session:512 csess 0xDDDDDD id 1 D/TC:? 0 tee_ta_close_session:531 Destroy session

My TA has correct output, no crashes,or other errors

Thanks.
