System Workbench for STM32

Hi Laurent,

Thank you for your reply! Before reading the reply, I think I found a possible solution.

In OpenOCD source code src/flash/nor/stm32h7x.c, I added the following line.

target_write_u32(target, stm32x_get_flash_reg(bank, FLASH_CR), FLASH_PG);

just prior calling "target_run_flash_async_algorithm()".

By the change, the problem looks resolved.

I'm not sure if this is the case and why revision Y doesn't complain about PG bit.

Once again, thank you for your attention.

Regards,
Atsushi
