Hello!

I use J-Link Plus HW10.1.

I recently upgraded J-Link software to version 7 and ran into a memory cleanup error issue. The last four sectors in STM32F413VH are not cleared.
I did some research, installed software versions from 7.00 to 7.68b, both 32 and 64 bits. The last correctly working version is 6.98e.

J-Flash and J-Flash Lite give the same memory clearing error when trying to clear the last 4 sectors.
At the same time, before cleaning, a message is displayed stating that the controller is write-protected and it is proposed to remove the protection. However, the write protection is not removed.


It helps only clearing these security bits through the ST-Link emulator and their software.

I tried updating the J-Link firmware, both to the latest and to the 2019 version, there is no difference.

If the controller was locked, then I can no longer clear it, even if I remove version 7 software and try to do it through version 6, it will give the same error and clear nothing.

Please check and fix this annoying bug in your software.

I checked J-Link base HW 9.3 too, it is exactly the same error.

The problem is very serious. If my colleague did not have a ST-Link emulator, I would have to throw away these controllers and replace them with new ones.

How can I change the option bytes for this microcontroller in your software?
