I just got a new PCB for HTCC-AM01 that replaces my earlier version that uses HTCC-AM02. AM02 works without any problem. Also HTCC-AM01 works fine but if I set GPIO07 LOW when resetting, the module goes to bootloader mode. I tested this with couple of modules and all of them go to bootloader if I have either GPIO0 or GPIO07 LOW and module is reset.
This is a big problem for me because I am using GPIO07 for a DIP-switch. I did not find any documents regarding any limitations of usage of GPIO07.
Why is GPIO7 acting like this and is there any way to make it possible to have GPIO07 set LOW so that the bootloader is not activated after reset?
