Is there any change to officially build also firms without the new bootloader?
I have done more than 1000km with last firmware that JRD McLAREN compiled for our boards and it is fine.

@JRD McLAREN made for us an firmware with the "tranditional" bootloader and it works fine.
so, bootloader seams to be the one that we should blame.

@mck1117 did you worked on JRD McLAREN unit that that @AndreyB send you?

@AndreyB

Do you think that is possible to locate users with the MCU revision and board that @JRD McLAREN mention here?

https://rusefi.com/forum/viewtopic.php?p=46791#p46791

Do you keep for example an xls-db with MRE versions and STM versions that the users bought?

software perspective:

This might explain why every next version after july fails!
https://github.com/rusefi/rusefi/releases/tag/20220812_release

So any ideas?
is it something at newer firmware's that needs to be changed for "STM32F407 VGT6" ?

Worst case you would be shipping to Matt if we cannot get this one already in USA to start.

Matt is at US?
This means customs/taxes and maybe months without my daily-driver

Both ( usefull and burned where purple)
these images are the best i can do

(i will try to locate the burned)

It is the custom version of @JRD McLAREN MRE+sd 5.55rc

Best I can do is ship my unit of custom version to @mck1117

to try to start the board and reproduce the issue?
Is any way that I can help also?

@JRD McLAREN
Can you assist?
have you updated any of your boards recently?

It is the custom version of @JRD McLAREN MRE+sd 5.55rc

Can I get TLE part number with software?

Full erase didn't work.
Also I noticed that when the flashing ends and it gives message to power cycle, The Fatal led is already on!

Hi, I can not update after my current FW (july 22) I tried all the next ones, august22, sept 22, nov22. I connect the device, update process goes normal, and when I reconect the device, the FATAL state led blinks premenately. I put the device to DFU mode and then I can sent new FW normaly, but only ...

New Question about check Engine Function! Ok, at start it blinks once, and TS menu says that in case an error, it will blink for 10sec by default. But what actually is an error? I wanted to check the functionality of check engine and I removed one injector, but nothing happened. https://imgur.com/a/...

Really curious about this project!

Did you finish the car?

My car's success story was based in this detailed topic.
I learned about Rusefi, by googling EFI + fiat 128!

This board is a private project or you will make it open source?
(The MRE board )

I belive that the most ballanced solution is this:
https://www.ecumaster.com/products/pmu/

16 analog inputs + can-keypad

Also very interesting board. I see no TLE.
We absolutely need more info!

Most of my customers as well as myself are big fans of programmable PDM. Mostly canbus based. The less wires in a car, the better for us. That however is just the view from my side, and not gospel. Ok, but I suppose that your clients are racing cars? They are not restoring/resto-moding vw-beetles,m...

Giving one example to make my point clear: My car used conventional lamps for everything! I replaced each one of them with led! My new problem now is that due to very bad engineering every time that I press the clutch pedal (which shares same structure with the brake pedal) for 1 sec the break light...

I really do not want to put this conversation out of its rails, but, making a pdm with only can connectivity it is not what the most people want. Aftermarket ecu’s are used by people that have the same steering wheel that came out of factory with their cars, same handbrake etc. The want additional f...

https://github.com/rusefi/rusefi/wiki/Lua-Scripting is the hard way GPPWM should be the easy way but it does not support CLT axis yet https://github.com/rusefi/rusefi/issues/3624 of course I prefer the Hard way. I already now this, but I was not sure if it can be used for lights. So I suppose that ...

Hi Again!
Is there any way to do this?:
If CLT is over 100c turn on this light! (dash warning light)

Try again with newer rusEFI firmware - the wideband controller is now controlled a little bit by the ECU (tells it when to start heating so you don't crack the sensor), so you need newer rusEFI to match newer wideband firmware. The latest prerelease on github has the new wideband protocol support. ...

Also STM32CubeProgrammer can not connect with Wbo
ST LINK works only on Auto mode:

Updates: It was a firmware issue! After updating to the latest release (i was on version 20220126) all the connectivity issues are totally gone! But:! At the same time a new problem popped up! :cry: during the update I was having connected the wideband add-on board. After the update the WBO stopped ...

Can you describe the specific problem you're having? What steps to reproduce, and what do you think should happen differently? there are two states of MRE so far: state 1 (everything works normal): no connectiviry issues at all! we can turn on and of the car normaly. ( mostly with cold engine ) sta...

Nearly to a success story. After a lot troubleshooting we finaly started the car! Many thanks to my friends Panos and Mitsos for their suggestions! :) Now we are facing a problem that it seams to be firmware problem. We have the same problem like Abricos ( https://www.youtube.com/watch?v=sjbBxfnneMo...

What wideband controller do you use? Anyway, probably yes, you can at least test that the sensor shows very lean while sitting on the desk. You can hold a lighter up to the tip of the sensor (lit or unlit) and you should see a response. actually it is your controller! but the version of the addon b...

Update: Didn’t try to start it again and fix the problems but I bought today a LSU4.9 Because it is second-hand (scrap yard / recycling cars center) is it possible to know if it’s good or bad? I mean without starting the car! Could I give at MRE 12V and get a very - very lean reading by having the s...

Mre pin 1

yes, both 1,5 have 12V+ and the dropp normaly () when I turn the key

no key, pin 29(mre) has, 0,9V
when i turn the key pin 29 has 1.2v!!
tuner studio reads 12.3v battery
