I've done a little research and found this:
- Various waveforms are stored in /opt/eink/images/ in *.wbf files.
- Helper links to these files (named after waveform versions) are in /var/local/eink/.
- If file /var/local/eink/dont_update is present, the waveform won't be flashed. Ever.
- If file /var/local/eink/update_flash is present, the waveform will be flashed and then the file will be removed.
So all it takes to stop flashing the waveform is to create file /var/local/eink/dont_update . Easy peasy.
I can create a
launchpad .ini file if someone's interested.
