- Mon Nov 10, 2014 2:42 pm #2429 Okay, folks. Endless reboot is fixed now. Looks like it's only happening on 'virgin' devices that never connected to a wireless network, when flashed. doing a wifi_set_opmode(0x0) will cause an exception as soon as the code enters main loop somewhere in the blobbies. This sets default mode upon startup to STA, and it should get fixed afterwards.
There's also a new command spi_wipe that wipes the whole flash clean. Could prove useful to get rid of any configuration leftovers that screw the blobs. As usual, grab the binaries at github and post about any bugs you've spotted.
Bonus in this update - SPI flash hexdump. For now addressesare in decimal only, sorry.

Likely a bug with your terminal software that's sending you unicode there. Try something VT100/VT102 compativle. minicom (I use this one), screen. putty if you're stuck on a windoze machine.
