OP-TEE error on new v5.0.0 SDK

[GCici]

Hi, i get this error when uboot starts on custom MP153D board:

E/TC:0 tzc_it_handler:79 TZC permission failure
E/TC:0 dump_fail_filter:420 Permission violation on filter 0
E/TC:0 dump_fail_filter:425 Violation @0xdff09000, non-secure privileged write, AXI ID 480

Can someone point me in the right direction? I cannot find a correspondence for AXI ID 480 in order to inverstigate over.

No further ideas how to debug this  from ST ?

@GCici  Did you find any clues ?

Hi, it was the DDR configuration file generated by CubeMX. Tried relaxed timings and it now works. But now I have another problem regarding i think u-boot. With 256Mb RAM i get the following error  just before loading the kernel:

Starting kernel ...

efi_free_pool: illegal free 0xcaee4040
efi_free_pool: illegal free 0xcaee1040
efi_free_pool: illegal free 0xcaedf040
efi_free_pool: illegal free 0xcaedd040
efi_free_pool: illegal free 0xcaedb040
efi_free_pool: illegal free 0xcaed9040
efi_free_pool: illegal free 0xcaed7040

then it goes in bootloop (i think because of wdt)

Same board with exactly the same hardware except for the 512Mb DDR3 module instead of the 256Mb one, no problem. All the 2 boards with the previous ecosystem run fine

Very interesting , where to set to relax those timings ? My 512MB board runs fine with ECO 1, but still have AXI 480 error with ECO 5.

Thank you so much.  It  would be a bit surprising if this fixes the AXI violation issue. In case of DDR timing issues, one would expect random type of errors in different DRAM locations than a consistent error at the same memory address. It would be more likely to be related to the initialization of the memory ranges of the tzc400. But you never know. will try this !

Did not work for me. Same error.
