Hello Im working with 1769 and i can't debug. This legend appear 15:target error from commit flash write: et: flash driver not ready
I do this Once you have managed to recover debug access to the MCU, the first thing that you should do is overwrite the image in flash with one that sets the system up in a safe manner, so that future debug connections will be successful without the need to recover debug access again. You would normally use the in-built flash programmer to erase the flash. but i couldn't understand the steps. Because i do this but dont work. Sorry but my english is very bad. When i wanna do a mass erase appear the next legend
