Debugging c code tips?

Hi - well, that sounds like a great start. I'm not sure if it helps, but I just manually flash then use this in gdb:

file bin/bootloader_espruino_2v19....elf

Rather than load - maybe load actually causes all the flash to be cleared, so since the elf doesn't include the softdevice it crashes?

The end result you're after sounds great, but personally I feel like you're maybe making this into a huge bit of work when it may not have to be - and making vast changes to jswrap_bangle.c that won't be in the official version is basically going to result in the two builds getting being forked which almost feels worse than the current situation.

So am I right in thinking that you're trying to port to pinetime/p8? Isn't it the case that basically all the hardware (LCD, touchscreen, accelerometer, etc) is already supported by the drivers that are built in to jswrap_bangle?

So if you defined BANGLEJS and BANGLEJS_P8 in the board.py file, and all the device entries there are filled in properly, and you add an init section to jswrap_banglejs_hwinit you should be a pretty long way towards having it working?

I know having the code for all devices in the one file isn't ideal, but you may be able to add P8 support by adding less than 100 lines to jwrap_bangle, which I'd be happy to upstream.

At least at that point you should have a pretty clear idea what had to change, and so what would be sensible in terms of moving things about to make it easier.

Personally I would like to move device drivers each to their own files (for instance Puck.js/Microbit could maybe share accelerometer code with Bangle.js), but it's quite a hard problem to be able to do that in a way that is efficient and also doesn't break anything when sometimes devices work in subtly different ways.
