Keyboard doesnt boots after tried to flashing with another firmware about ergodox-firmware HOT 4 OPEN

not sure if i should have spent so long working on this today lol, but i got it!

two ways to fix

first way

• if you comment out these two lines it should work

it's this for loop that's keeping the function from returning.

of course if you're using macros (i can't remember if i ever got them to work) this isn't the solution you want lol.

second way

• install teensyduino https://www.pjrc.com/teensy/teensyduino.html
• run the sketch below (modified from here) to set every byte in the eeprom to 0xff

#include <EEPROM.h>

void setup() {
  // initialize the LED pin as an output.
  pinMode(11, OUTPUT);

  for (int i = 0 ; i < EEPROM.length() ; i++) {
    EEPROM.write(i, 0xff);
  }

  // turn the LED on when we're done
  digitalWrite(11, HIGH);
}

void loop() {
  /** Empty loop. **/
}

for whatever reason, initializing all eeprom bytes to 0x00 doesn't seem to work. definitely a bug, but not one i'm going to try and fix right now (lots to do).

thanks for catching this.

bug confirmed on one of my boards. this is really weird.

it is, the only difference the keyboard is meant to have is an entirely different, rewrited contents, isnt? im not expert on it but i cannot get how this bug happens, the hardware is the same of course

i don't understand it yet either -- and i may not have time to figure it out, but i've been looking at it a bit today.

if you unplug the TRRS jack, and then unplug -> replug the USB, it will work, though it blinks an error (i'm still trying to remember what that means lol, it's been a while). if you then plug in the TRRS cable (quickly, maybe not too quickly) both sides will work.

not really a workaround, but interesting.
