Compile firmware for wipy2.0 success, but after reboot is red light

[pedro]

Hi, ive tried to compile the firmware from scratch and to flash my wipy2.0. Ive followed the instruction from the github https://github.com/pycom/pycom-micropython-sigfox and all went fine.
I`ve successfully flashed the firmware, to the point when the board reboots. Then i unplug the wire between gnd and g23, and reboot the board, but instead of the blue blinking led now there is a full red. Only way is to reflash with the flasher tool.
any help is appreciated, thanks

@robert-Thank you, worked perfectly

@pedro You have to erase the flash before and then reload. There is an inconsistency between the pre-built images and the self-built ones. Erase the flash with:
make erase
and the reload with
make flash
You have to push reset before each make command, and the gnd/g23 wire has to be in place. Unfortuantely, the content of the local file system will be wiped out too.
