Reference from CMSIS-Core, the description for __STATIC_FORCEINLINE void SCB_EnableDCache(void)

Before enabling the data cache, you must invalidate the entire data cache SCB_InvalidateDCache(), because external memory might have changed from when the cache was disabled. After reset, you must invalidate SCB_InvalidateDCache() each cache before enabling it.

So I think you can try to SCB_InvalidateDCache() before SCB_EnableDCache().

On the other hand, can you provide the error message or the state of the error?

I think that helps figure out the root cause.

Changing from FW_H7 1.11.0 to 1.11.2 worked for me.
