STM32H563ZI Flash Bank Swap

[IanLin]

Hello all,

I am currently developing on the STM32H563ZI and encountered an issue where, when swapping to Bank 2 to erase/write flash, it simultaneously erases the same address in Bank 1. Here are the steps I followed:

1. Swapped to Bank 2.
2. Used STM Programmer 2.16.0 to flash a bin file to the address 0x8100000.
3. Used STM Programmer 2.16.0 again to flash the same bin file to the address 0x8000000.

At this point, the code initially flashed to 0x8100000 was erased. Subsequent tests with writing only a few bytes also resulted in the same situation.

Are there any settings I can adjust to avoid this situation?

Thank you very much!

Hello @IanLin ,

I've tried to replicate the problem but everything worked fine for me. Can you share your option bytes config and the binary file ?

Thank you in advance !

Logging output at Level 3 might also be helpful to understand the process / sequences

Try merging the TWO .BIN files into a singular .HEX file and applying that in a SINGLE operation.

Hello,

Thank you @Tesla DeLorean for the valuable suggestions ! @IanLin This issue will be resolved in an upcoming software release.

Hi @Maryem ,

Thank you for your reply. The swap configuration is as follows:

Additionally, I performed other tests with similar results.

Steps are as follows:
Step1:Erase all sectors
Step2:Swap_Bank set 1

Step3:Write some bytes to 0x8100000

Step4:Write 4 bytes to 0x8000000

At the same time, the data originally written to 0x8100000 gets erased.

This is the programmer configuration:

Thank you!

Hello @IanLin,

Thank you for your feedback. We're working on a fix that will be included in a future release. I'll make sure to keep you informed on the progress. Your understanding is appreciated !

Hi @Maryem 

I am also experiencing similar issues with STM32H5 FLASH programming with STCubeProgrammer when BANK_SWAP is enabled.

Could you advise when an update to STCubeProgrammer is expected?

Kind regards,

Simon
