Hi @TheRealPaulie,

Thank you for your patients, would it be convenient for you to share the qsys diagram and also the NIOS project is possible?

Will be helpful for us to further check on the issues.

Attached below is some user guide for flash memory for Max 10, you may refer to the section 4.2 which explain the method of utilizing the operation on flash memory:

Hello,

I solved the problem. It was the configuration of the BSP.

I was booting from FLASH but using the FLASH as program memory (I hope that terms I'm using are correct - I'm not a uController specialist). After I changed the settings to copy the code from FLASH to RAM and boot it from RAM, I was able to delete and to write the FLASH again.

Regards,

Paul
