Apologies in advance if this is an obvious question or has been answered before.
I tried to flash a USB card but I think it is corrupted. Bought a new card and it appears as ‘locked’ in BalenaEtcher. I’m using some GitHub code for a self assembly camera. The original SD card was pre-loaded with the code. I just need to flash my brand new SD card and can’t. As you can probably guess my knowledge of all this is near zero… Thanks !
