Just realized this has never been announced.
The boot loader can now utilize both, CAN and serial port for updating the firmware, see here: viewtopic.php?t=2094
The CAN protocol has been implemented on Damiens Canlogger7500 (perhaps also runs on Petes hardware) and also in a python script in the bootloader repo.
You can also find binaries there.
If you dare updating an already commissioned inverter you can user stm32_bootupdater from the previous version: viewtopic.php?t=1119

Re: Combined CAN and Serial boot loader
If I have understood the current developments correctly, I will no longer need an ESP8266 in the future because everything runs via CAN. How should I proceed if I have a bare LDU board or want to bring an old one up to date. I have an InnoMaker USB2CAN module, ST-Link V2 and STM32CubeProgrammer on the computer, as well as physical access to the board. What else do I need?

Re: Combined CAN and Serial boot loader
Yes that's correct.
You will need a peer for CAN communication. Either some CAN adapter that is supported by oic or an ESP32 with CAN transceiver and the firmware linked above. Pete has made a small board and Damien a larger one.
Apart from that you need this boot loader and a recent firmware like 5.27.R that's it

Re: Combined CAN and Serial boot loader
Would be helpful to have links to the different options for Interfaces between Win10 and CAN. I have no idea at the moment, should create a wiki for this.

Re: Combined CAN and Serial boot loader
Does this relate to Zombieverter also, or might it in future?

Re: Combined CAN and Serial boot loader
I think its liboi version might be too old, apart from that it should work just as well
