Tool/software:
Hi Expert,
customer is using SDK9.2, and they are using HSFS AM62A, customer feedback they are facing below random error:
ERROR: Bootloader_verifyMulticoreImage:655: Failed to authenticate Image
Some tests have failed!!
it will not occur every time, and it can be work around by retry one or two times below function.
Hi Meet,
Background
We have modified the linker.cmd script, changing the load address from DDR to MSRAM. Will this have any impact? We made the change based on the IPC demo project’s linker.cmd, but since MSRAM only has 512KB, which is not enough space, the BSS data is still mapped to DDR.
After the link is modified.zipBefore the link was modified.zip
Investigation
Added log printing and located the issue to the abnormal return value of the Sciclient_readThread32 function.
This function appears to be used for reading 32-bit data from a specific thread channel of the Secure Proxy.
Under normal circumstances, the return value is a flag of 2, and the request (req) and response (resp) are the same.
In abnormal cases, the return value is 0, and the request (Req) and response (resp) are different.
The meaning of the flag
Some attempts
I added retry logic in the SBL code. From the results, it seems that retrying is effective. Most of the time, a single retry is sufficient. However, there are occasional failures, which might suggest that three retries are not enough?
Do you have any ideas for analysis?
Best Regards,
rudao
