Borked firmware on Inspire 1 remote Model GL658A (Not connecting to USB device)
First off, I'm using WM610_GRCP_MFI368_V1 board board. It's an embedded linux system and is what is used to send video/telemetry out the USB port. https://github.com/o-gs/dji-firmware-tools/wiki/GL300-Interface-board
If after following this your device start boot-looping, you will probably need to flash a new kernel! Follow the instructions on the wiki listed here: https://github.com/o-gs/dji-firmware-tools/wiki/Flashing-firmware-on-DaVinci-media-processors

Cwerg: C-like language that can be implemented in 10kLOC
Perhaps these have already been dealt with and I'm missing critical information. If so, my apologies. Great work, in any case.

Somer examples are here:

This section contains a list of features that are unlikely to be added to the Cwerg backend:

If you can live without them, it can be a replacement for LLVM.

Where can I find resources and guides on how to build compiler backends?
Cwerg has backend that can be used as JIT and is written with readability in mind. Additional documentation can be found here: https://github.com/robertmuth/Cwerg/tree/master/Docs

Syntax Design
I was also going down the path of bike shedding concrete syntax for my language Cwerg before pulling the plug on that effort and just using s-exprs. I managed to make the s-expr quite succinct by carefully choosing the order of arguments so I can omit optional ones. Also very helpful was to use square brackets for list, e.g. (call fun-name [arg1 arg2]). This simplifies parsing a little bit and is easier on the eye. Here are some Code Examples

November 2022 monthly "What are you working on?" thread
I am iterating over the languages features for Cwerg's Frontend which aims to be a low level language with about the complexity of C but with some of the comforts of modern languages. I am especially happy with the choice of adding sum types. Relative to C the current feature set looks like this: Removed: * arrays decay to pointers * bitfields * separate compilation (more of a backend issue) * pre-processor * varargs * implcit type conversions * (untagged) unions * ++/-- * comma operator * implicitly nullable pointers * goto
