Hey guys,

I used to be able to download my program to my stm32f723 discovery, but for some reason now when I want to flash even the untouched code, which I got by generating the stm32 cube project I always get errors: Contents mismatch at: 0800406BH  (Flash=00H  Required=01H) ! - I get like hundreds of this type of errors.

and 

Error: Flash Download failed  -  'Cortex-M7'

Can you please help me how can I fix that?

Use different tools? Use different settings? Question lacks a lot of context.

If failing in single bank mode, used dual bank mode.

Check cable

Check option bytes

Use ST-LINK Utilities
