I would like to report back on a problem that is flooding the engine.
only on st32f407 I have all the outputs which are active during power-up (for about 2s) then the code works fine.
if i run a reboot command it does not happen.
since the removal of folders newComms by comms and comms by comms_legacy.
stm32f411 does not accept board change and stop serial com.

no problem in teensy 3.5
no problem in mega 2560
if anyone can help i will be happy.

Which FW version? I haven't seen that kind of problem.

After 202202.
Long boot on power.

Pazi88, if you want I have some addition for the CANBROADCAST WAG.

Correction, after a few multiple attempts.
all the injectors and all the coils are driven approximately 300ms when the card stm32f407 is powered up;
if we launch a boot command by tunerstudio it starts again by doing 2 identical cycles, all the injectors and all the coils are driven approximately 300ms and after 100ms driven approximately 300ms again.

I have not had this problem, but im using 202108 , 202204 still doesn't work correctly on STM that i have found, im running 4 of my own cars on the STM hardware.
How are you compiling the firmware -0s,-3s.
I find the STM32 isn't all that happy with -3s compiling, i stick with -0s.
No problem at all with stm32f411 on 202204.

I've found.
My problem came from the CAN.
I don't know why my compiler didn't want to accept the syntax: #if HAL_CAN_MODULE_ENABLED.
I replaced them with: #if defined(STM32F407xx) in the src/STM32_CAN files and in board_stm32_official.h and ino.
It works fine and now the CAN bus is transmitting correctly.

on the other hand I had made a hardware assembly with a vp230 in 3.3v it does not work. Came back with a 5v mcp2551 to get it working fine.

What are you using to compile the code? In PIO it works fine.

[NickZ]

Haven't had that problem either in Arduino IDE.

[flex-ALE]

i am using arduino ide with github.com/stm32duino 2.2.0
modified variants 411CE and 407VG because these are the cards I use.
the initial syntax passes during compilation but is not taken into account and causes the code to do strange things.

Im using stm 2.1.0.
Make sure you use the current DEV for the STM firmware.
Im not having the issues your having.
