I dont think it's used.

In the bootloader makefile it points to some files/folders that does not exist:

LDSCRIPT= $(CONFIG)/stm32f4ems/STM32F407xG_CCM.ld


CHIBIOS = $(PROJECT_DIR)/ChibiOS3


If there are no software options, I think maybe adding a ST-Link are the closest I get.

I saw that in the code, but did not understand completly how it works.

I could not find the STM32F407xG_CCM_bootloader.ld file either.

I am looking for a way to upload firmware via usb.

Are there any way to do this yet?

I know about DFU, but need a software solution only.

One way could be two usb ports, one of them with VBUS to Boot0, but it's not a ideal way.

the MSV70 has been cracked open to work standalone even in chassis as basic as the E30, I will admit I haven't checked what ECU gen is on the N73 :oops: I'm guessing it is an MSV7x series ECU. Edit - looks like its an ME9.2 unit on the N73 Double edit - I may have a DAMOS file for the 760 M9.2 remi...

Even if he finds the key, open question is how many control units would have to respond on CAN bus for the security system to start the engine. Open question if it would refuse to start unless SRS or gauge cluster or who knows how many other control units are responding on the bus. Dont worry about ...

Ah okay. The OP made it sound like it was already decided, and provided no context or reasoning :) The Infineon and ST parts look quite similar functionality-wise, but the Infineon is kinda hard to source. I'm not a fan of sketchy ebay parts. The older 7209-2 is available from normal places, but it...

Had to do some PID reading, as I haven't used that since school ages ago.

Have you measured the current the throttle needs?

Does the H-bridge control method affect anything? (3 wire vs 2)?

Springs have fairly low inertia.

That's right.

I think with the gear ratio and motor effect, the spring dont affect the motor that much.

MaxxECU's E-Throttle works good as well http://www.maxxecu.com/webhelp/settings-ethrottle-throttle_control.html Integral limiter extended information A common problem with PID tuning is that you want to use a high I-gain to get a fast and exact response, but it might become unstable. This is because...

Why would we ever use an NRND part when there are better parts available for less money that are still active? Seems pretty foolish to pick a random part without any research, especially one that’s NRND. For example the ST L9960 is designed for ETB applications, automotive rated, fully protected, a...

As a guidance for what variables needed, check the software and help-files for standalone ecu's with good working E-Throttle.

Screenshot from PC-Link Software:

They are connected to VDD.

I see they are both connected to VDD in the Nucleo schematics as well.

What is the exact part number of stm32f4 which has worked and what is the exact part number of stm32f7 which does not work?
How sure are you about pin compatibility between these two chips?

STM32F407ZGT7

STM32F767ZIT6

I recall comparing the datasheets, but maybe it needs another look.

STM32F767 MCU

Did you get it to blink status LED with STM32F767 or any other chip?

I have a F767 soldered properly, but still the same as last time.

No led blinking, just a weak constant light.

Both SWD and DFU working.

Do you have any idea?

I have one with a F4 that most is working.

But I had to order new pcb's cause of the lack of mask between pads.

It's impossible to get right as it is.

I think a F7 will work when that is resolved.

Looks like this project has a lot of HW engineers and leaks of programmers.

Well, that's how it's usually done.

Hardware needs to be in place before programming.

Time to introduce the project. It's a PNP Ecu made for all ME 7.1 and ME 7.5 cars. It has: 2x TLE7209 H-bridge drivers for E-Throttle 2x CJ125 LSU Drivers 2x L9651 Injector Drivers, 8 x 2.2 A outputs 10x Digital IO 16x Analog Inputs 22x Low Side outputs in addition to the injector drivers TLE8888-1Q...

Do we have a thread suitable to rail pressure control logic discussion? I assume this thread is about the board. Am I missing something or are we supposed to start by figuring out what logic is needed to do what exacly with high pressure pump control? What's the issue about the fuel pump? Just down...

Thanks for sharing the comparison. I see -- 2015 MC33816 was release to production. This could account for why the MC33816 is more readily available. -- 2018 MC33PT2000 was released to production. -- 201? PT2001 has not yet been released. The eval board is listed but no stock at the time of this po...

Seems like the PT2000 are a better option.

Finally found the differences:

Just to clarify, I am very sure about it.

There are almost no market for diesel, so only driver for GDI are needed.

Also the oem driver IC in a bosch ecu I have here says 65V.

http://www.bosch-semiconductors.com/automotive-system-ics/engine-management-systems/cy335/

So why does Bosch Motorsports own driver for them say 65 Volts and max 72V? http://www.motorsport-systems.co.uk/wp-content/uploads/2016/05/Manual_HPI5_2012_02pdf.pdf And Link ECU has made a GDI version with max boost of 65V? This one works fine with Vw and Audi injectors. If you open the base map fo...

The bottom left of this schematic has pump control. I believe that is the same circuit used on the PT2000. The key problem with knowing if this will control the pump, is that are do not have a pump to control. A control bench or an engine would resolve those kinds of details. Yes, I looked at the s...

Should we test this?

But how? We need high pressure in the rail as well.

Oh, it doesn't have the pump/rail pressure circuit?

Was looking at the PT2000/2001, and saw that was integrated.

I have all the needed data for the TFSI now, so need to get something up and running

Should we test this?

How about the firmware part to control it, is it much work?

BTW I haven't deleted any folder or anything.

You cloned into that directory? not copied?

Try the git command(s) from C:\Users\user\Downloads\rusefi-master Notice this is one folder above "firmware" I believe git command should not care Yes it does. It does not work in firmware folder. You have to be in the git folder. If you show hidden files, you see the git folder in the fo...

The PierBurg Throttle-body are basically the same for all cars as well.

The same parts in different shapes:
