It does not help me.

__DSB(); is not possible because of thumbs mode and arm mode is not supported by my compiler (keil).

I don't see how this is a hardware bug??

It is not possible.

main.c(152): error:  #1113: Inline assembler not permitted when generating Thumb code

and when i want to use

#pragma arm

main.c(151): error:  #1114-D: this feature not supported on target architecture/processor

It is not possible to use dsb.

This is really a ***** hardware bug of the STM32.

Then do the Keil equivalent for inline assembly for ''dsb'' instruction.

I think the uC should make a reset as described in the reference manual, and not only sometimes.

maybe st solved the silicone bug in their libary with the use of the ''dsb'', but i cannot use it.
