Part Number: EK-TM4C1294XL

Hi everyone

i was testing hibernate module while doing that i made a mistake and make a configuration such that system go to hibernation on reset and wait for tamper interrupt to wake up, as it wake up go to hibernation again and repeat. Now i am not able to erase the flash memory or overwrite it with correct version of my code.

Is there anyway i can Erase flash memory?

There is "Unlock debug port" utility in LM Flash Programmer under the tab of other utilities. I was able to erase my flash by this.

Hello Dilawar,

Thanks for following up with how you solved the issue, Flash erase is the last resort for solving that but a reliable one. Hopefully you won't have further issues!

You could add an extra safe guard interrupt (like a GPIO interrupt) while making modifications in the meantime to avoid needing to take the erase Flash step if you have a bug?
