Hello,

 

The project run NorFlash, but operate NorFlash function in the SRAM to execute.

 

After I used AHB command to read Norflash, go to operate flash function, and it happen an abnormal action occurs.

 

Operate NorFlash :

 

S1. Write Flash (IP Command)

S2. Read Flash (AHB Command)

S3. Erase Flash (IP Command), Used Erase Flash, Found at  0x600C8000~0x600C801F can't erase.

 

 

I suspect it may be a cache problem, currently the Project enable D-Cache and I-Cache, Will it be read Cache and Flash out of sync relationship?

 

Best Regards

Jim
