Hi There.
I tried to erase Flash using F021 API, but failed during Erase Check. (used : Fapi_issueAsyncCommandWithAddress(Fapi_EraseSector, (uint32_t *)u32EraseStart) )
As a result of checking the Erase Sector area with the memory browser, the bit flip is confirmed. (0xFFFFFFFD, 0xFFFFFFBF, etc)
It was no issues with the RM44 and RM46.
I referred to the solution of a similar case on the forum, but rather side effects such as not booting occurred.
How can i resolve this issue?
My link.cmd file are:

Best regard.

Hi Jinwook,
I created one example project for Linker based ECC generation example.
RM57_Linker_ECC_Generation_TEST.zip
In this project, i filled unused region of the flash and bank-7 with the 0xFF values, also filled ECC region with corresponding values.
After running this project i verified and found all the unused flash regions with 0xFF and bank-7 also filled with oxFF.
To run this project properly make sure below two things.
1. Make sure debug settings as below
2. If you are using latest CCS then make sure to ON below option
Note: I didn't check with FAPI routines yet.

Thanks & regards,
Jagadish.
