Firmware update via CAN using OpenBLT

Dron has just implemented OpenBLT for some boards including MRE F4 and both Proteus Fx builds.
A lot to be figured out but we have something now!
https://github.com/rusefi/rusefi/pull/3430 is the PR
https://github.com/rusefi/rusefi/wiki/Firmware-update-via-CAN are the limited notes.
A million of open questions as of today:
Would random "USB transfer CAN isolation canable open source CANDO interface card debug CAN box bus analyzer" from aliexpress work?
Are there existing JLCPBC fab files for
https://canable.io/ or would anyone be interested to contribute?
While stm32f042 are not very available those are somewhat available. Also worst case we can swap stm32f042 for pretty available stm32f407
The big picture is having a more water proof rusEFI ECU eventually. Considering that USB is not ideal at the moment we have code to update firmware via CAN and tune via Ethernet. Maybe one day we will find a way to tune via CAN but that's kind of a separate topic more relevant for

pretty available on jlcpcb is GD32F103C8T6 or GD32C103TBU6
curious, what's inside those canable firmwares? from my understanding, this should be something like a serial to can bridge? or it is trickier, and PC software uses some proprietary usb-based protocol?

Cando adapter
https://aliexpress.ru/item/4001164534407.html from Ali tested and works just fine under Linux.
Code: Select all

is it open source (cando thingy I mean)? I wish there were source codes - just curious how difficult would it be to make a similar one, say, out of a blue pill + canbus shield.

You can use open hw compatible with this FW

Thanks!
I looked through the code, so, from my understanding, it's not just a plain usb-serial interface inside, but rather a fully-featured usb device.
As for blue pill - I've heard of successful implementation of usb AND can at the same time, but first, that's way tricky, and the resources are limited.

Which option does RusEFI need?

Myself I am interested only in update via CAN.
Mark might be curious about firmware encryption in addition to that update via CAN.

CANable Z PRO was tested with MRE. Still under Linux only.
Windows testers are welcome.
