IsoTp ISO 15765-2 in rusEFI

Post by 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)
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 :)

@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.

Update:

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

Code: Select all

C:\Users\Dell2019\Downloads\windows-USB2CAN-fw-tools>dfu-util.exe -a 0 -s 0x8008000:leave -D usb2can_v23.bin

Found boot0 pad. To enable USB DFU power device while applying VCC 3v to boot0 pad.

Device is read out protected so I have voided warranty. This is now a PCAN device thanks to https://github.com/rusefi/rusefi_external_utils/blob/master/CAN/pcan_canable_hw.hex backup of https://github.com/moonglow/pcan_cantact

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

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

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
Same one that I took photos of above.

Just pushed socketcan_connector.sh script into bundle bin folder https://github.com/rusefi/rusefi/commit/bb5fc7fcee97081c70bafc418729e4a6859a964d

If anyone has SocketCAN hardware and rusEFI please try and report! https://github.com/rusefi/rusefi/issues/4277

Tested this with my "ECAN" peak adapter - works with P-CAN viewer.

Unfortunately I got connection errors from TS.

ArrayIndexOutOfBoundsException is a red flag https://github.com/rusefi/rusefi/issues/4370

it's somewhere inside PCAN native stuff, open question if their PCAN-Basic has enough source code for us to troubleshoot this further.

I would suggest addressing the unexpected CAN traffic first and testing once iso-tp is the only activity on the bus. If iso-tp would work by itself we would move to adding understandable CAN traffic in addition to iso-tp next ut as is it's just too much weird at the same time.

understood. I will check out these strange frames first and report back!

The strange CAN frames are fixed as of PR#4376

Happy to report that TS Via CAN (ISOTp 157650-2) works.
There is alot of debug in the console window due to filtering of verbose and the wbo2 messages.
I think this makes the CAN Tx/Rx a quite laggy, which in turn makes TS laggy.
However I was able to see the gauges update and change settings successfully via TS.

Attached is the debug log.

Please let me know if you need anymore testing.

NB: 0xEF50000 is the Wbo2 voltage and engine running frame at approximately 20Hz, 0xEF51234 is a test lua frame at approx 1Hz.

I am not sure how much console debug (or connector debug) would affect throughput, maybe it in fact plays a negative role.

Would you be interested to look further into it? try TS without console running? Try with custom firmware and/or custom java connector with debug statements removed from the source code?

Happy to.

TS via usb/serial is at this point much qucker.

I will have a look at the java connector/bridge and compilation steps to see if I can try and remove the debug print and see if there is any improvement.

it's not amazing around 10 hz :(

It's low enough for me to wonder what layer is broken. https://github.com/rusefi/rusefi/issues/4203 is somewhat relevant
