What is the proper "magic" sequence when plugging the IBMPC-USB converter to force it into the bootloader?
I loaded TMK onto a (orihalcon-made) Soarer's Converter cable. It works, but I forgot to add the
BTLD command to the layout and now I can't go into the bootloader mode to make further changes to the layout I want.
FULL GORY STORY AHEAD:
I have plenty of (orihalcon-made) Soarer's Converter cables. As you surely know, Soarer is by now abandonware and I've run out of patience. I figured that, given those cables have an ATmega32U4 chip, it should be possible to load TMK onto them and use them as TMK cables instead. So...
- I went to the TMK Keymap Editor, IBMPC-USB Converter(ATmega32U4) , defined my layout and downloaded the unimap.hex file.
- I started QMK Toolbox, opened unimap.hex, set Auto-Flash on.
- I ran Soarer's SCBOOT.EXE to force the Soarer's Converter cable into bootloader mode.
- Automatically, QMK Toolbox flashed the .hex file onto the cable.
- I unplugged and replugged the cable, and it is now detected and works as a "TMK IBM PC keyboard converter (FEED:1BEE:0201)".
Given this was now working, I decided to make a few further adjustments to the layout in the Editor. After downloading the new .hex file, I realized I could not go into the bootloader, as I had forgotten to add the
BTLD command in the first layout. Soarer's Converter cables do
NOT have a physical RESET button, so that is not an option.
Running SCBOOT.EXE again does not work, as the cable is not recognized as a Soarer's Converter anymore.
According to
https://github.com/tmk/tmk_keyboard/wiki/TMK-Magic-Command , there should be Magic commands available, including
Shift-Shift-Space-B to jump to bootloader, but I haven't been able to make that work, either. So, I got this datum wrong AND/OR I'm doing something incorrectly.
So, what is or should be the way to go into the bootloader?
Thanks.
P.S: upon boot, TMK reports itself as
TMK:56e88e/LUFA:d6a7df .
