IsoTp ISO 15765-2 in rusEFI

[AndreyB]

Central thread for IsoTp ISO 15765-2 in rusEFI

On the one hand we have 15765-2 implementation in firmware and ELM327/15765-2 console TS proxy, on the other hand open question if anything with real RS232 on the path would ever work specifically with TS protocol? does TS protocol NOT help if RS232 is on the path?

One day maybe https://en.wikipedia.org/wiki/XCP_(protocol)

[AndreyB]

https://rusefi.com/forum/viewtopic.php?f=13&t=2209 is disappointing

https://legacy.uavcan.org/Implementations/Pyuavcan/Tutorials/1._Setup/ has some pointers maybe at nicer hardware

One day maybe https://en.wikipedia.org/wiki/XCP_(protocol)

OpenBLT uses XCP over CAN. And may be over some other interfaces too.

Just ordered Korlan https://shop.8devices.com/index.php?route=product/product&path=67&product_id=89 this one looks amazing! Also cool that those are designed in Lithuania.

Will totally try to run https://github.com/moonglow/pcan_cantact on it

Another option maybe https://www.aliexpress.com/item/1005003493448473.html Vag V2 VAG B03-ST V20.41

Someone would have to design a case for it

@andreika has just fixed one last bug and ISO-TP PCAN connector works! We connect TS to ISO-TP via a TCP bridge in rusEFI console binary. At the moment only tested on Windows, might need additional packaging magic should eventually work under Linux.

Details?
What about update rate?

Got my Korlan USB2CAN and so far I am unable to switch it into DFU mode

On Windows 11 I have it displayed nicely in Device Manager

I've downloaded windows-USB2CAN-fw-tools but USB2CAN_DFU.exe tool does nothing silently on my Windows 11.

They also mention a linux way in documentation https://www.8devices.com/media/products/usb2can_korlan/downloads/Korlan_USB2CAN_User_Guide.pdf

[AndreyB]

Update:

downloaded _another_ package and it has _another_ version of usb2can_dfu.exe which works - it does switch device into DFU mode.

Found boot0 pad. Device is read out protected so I have voided warranty. This is now a PCAN device thanks to https://github.com/moonglow/pcan_cantact/releases/download/v1.5/pcan_canable_hw.hex

Middle LED looks to be PD2, further away LED looks to be PC12 - one day we might make a custom version of https://github.com/moonglow/pcan_cantact/blob/master/Src/pcan_led.c

Just fixed a bug and got rusEFI console to work via PCAN.

Hey Andrey. I will try this too on my spare USB2CAN adapter. Is it just a matter of pulling Boot0 to ground and then running the DFU unit will the PCAN_CANABLE_HW?

really depends on what kind of USB2CAN you have with what MCU
