Hi Guys,

how about this board:
https://www.aliexpress.com/item/32827402179.html
?

It's a ZG version. Meaning it has a bit more ports (less important) but also the 1MB flash. I haven't found similar one with the VG version (same number of pins, but 1MB flash. Using the 1MB flash chip would make a board compatible with both Speeduino and RusEFI. How about that? Is that a lot of effort to make the STM32f407VE software run on theh STM32f407ZG chip?

Best regards
Greg

Hi, it's very cool that you porting speeduino to stm32, but I'm getting a few erros during the compilation to STM32F407VET6, like "src/board_stm32_generic.h:14:24: fatal error: Fram.h: No such file or directory". Can you help-me to compile to STM32, I can help you on some problems like serial flash etc... I have speeduino mega 2560 working flawlessly on my VW Polo 1998.
Thanks! Let's make a high performance ECU.

That is also an option. I think it would not be very difficult software wise. The biggest issue is that it is not pin compatible with the "other" black version of the board. I have both versions here and for now i focus on the STM32F407VE for an SMD hardware board that works.

Hi PabloMuro nice you are interested! I am no where near a working implementations of hardware yet so be patient . The summer is over so i hope to put some time in this project again. I see the timer modifications made its way into the ST stm32duino core! That is good news for the development.

I must say i get the same error as you do with the most recent version of the speeduino code base. I will check and see if i can fix this. I think it has something to do with the Preprocessor macros are not making a distinction between the STM32duino core of rogerclark stm32duino and the ST stm32duino core.

Hi All

I have been trying to get my development environment working again. During development of the timers en battery backed sram i used the ST-Link V2 clone to flash the STM32F407 in my software. I could not use the USB port for anything as the usb port told me the "USB enumeration failed"

The PCB of the black STM32F407VET6 boards have a hardware design flaw! I noticed a 1.5k pull up resistor [R21] to the 3.3 volt in the schematic. This enumerates the device on the USB port before the device is booted and can respond to the host (computer). The stm32F4 have this resistor in the MCU itself so no need for an external one. So to get the USB working remove the R21 resistor from the board. Now USB works! (Also USB serial just like the arduino mega)

Now if you use the arduino IDE with STM32duino core and the install the STM32CubeProgrammer software
https://www.st.com/content/st_com/en/pr ... eprog.html
You can download the speeduino firmware to the STM32F407 black

1. putting the jumper BT0 on position 1 (slide it to the 3.3volt rail) .
3. Plug the device in an USB port
4. Reset the device.
5. Arduino IDE select Board: GENERIC STM32F4 series
6. Arduino IDE select Board part number: "BLACK F407VE"
7. Arduino IDE select Programmer: "STM32CubeProgrammer DFU"
8. Press upload

Ow and first debug the compiling errors. But that is something for tomorrow.

I have built hardware and have ran other firmware on it, but i can't get speeduino to compile without errors.

Nice Board! I see no battery? That unfortunately means the current version i am working on will not work for you (yet). The battery backed sram does not store a tune without a battery.

The good news is that the black eBay boards battery is not to shabby. The board still remembers my tune. That is more than a year of lying on my desk without power and still the original battery.

On another note, tonight i tried to get again to the point where i left off a couple of months ago. Not there yet but close.

[NickZ]

not sure i understand, why are you needing a battery to keep the tune?
What im currently working with has no trouble without a battery.

Thanks for reply, I'm thinking on make my own board with STM32F407VET6 almost like this image. What you think?
