TB config error: GM-SENT, latest Discovery_F407 FW

[tmbryhn]

I'm trying to get GM SENT ETB to work on the latest Discovery_F407 release on custom hardware running STM32F405RGT6.
Everything else has worked flawlessly on FW versions from 2024.

After setting up the accelerator and defining all the ETB and SENT parameters, I get the following error:

Download link to .MSQ:


I get no error when I define two conventional analog inputs for the TPS (everything else being equal), so it seems to me that we're dealing with a config logic bug. I've successfully run this ETB on older firmware from 2024 with no config errors, albeit with glitchy TPS values which is why I'm trying to update the FW as I've been told that handling of SENT protocol has gone through some improvements.




Hope we can solve this issue. Thanks.

I'll try to reproduce your issue. We did some touches around etb recently. May be I broke something.

[tmbryhn]

Thanks for the swift reply. That's awesome

Can not reproduce on uaefi.

Can not reproduce on uaefi.

are you using snapshot or cancelled 0427 release? that's one obvious difference between the setups. I guess another difference is uaefi vs discovery?

[tmbryhn]

Seems this is a Discovery specific issue. I tried nightly build a couple of days ago with same result.
Ie; I think you'd need to run Discovery to reproduce the error.

[AndreyB]

current discovery does seem to have EFI_SENT_SUPPORT=TRUE probably because it no longer fits

just fixed the confusion by hiding it from TS https://github.com/rusefi/rusefi/commit/aef69b99ae5ba5cbc9ce7dee7e896f8cbc84fa37

Thanks for the fix
Should I download snapshot or nightly for test?

what is the URL for snapshot? what is the URL for nightly?

i am fixing the confusion, not SENT on discovery

[tmbryhn]

Just downloaded the latest F407-Discovery snapshot, and not too surprisingly SENT TPS support has now been removed completely.

Is this a "work in progress" issue, or can I assume that SENT is gone from F407-Discovery forever and that I would need to compile a tailored configuration of the firmware to have SENT working on my custom hardware?
Some clarification would be much appreciated.

[AndreyB]

SENT is gone from F407-Discovery.

[tmbryhn]

Thanks for the clarification.

While I'm in the process of compiling my own codebase and trying to get all of the required stuff set up; is there a chance that we could look into the reason for the ETB config error while SENT TPS is enabled so that I can get the engine setup working again on the latest Discovery firmware?
