Re: my Engine Control Module

Now also supporting Kinetis - https://www.youtube.com/watch?v=-Vm4fQnetag

Why no 'chSemSignalS' function?

How wrong are the things I am doing if I need chSemSignalS function? Here is my universal wake function which works both in I and not-I context, also works regardless if we are in locked context or not: // ChibiOS does not offer this function so that's a copy-paste of 'chSemSignal' without locking v...

Re: my Engine Control Module

We have another unexpected random "fun": we have rusEfi working fine on F407 and F469 and a few F7 but today we got affected by what seems to be hardware watchdog on F405? The firmware compiled for that chip seems to be constantly rebooting itself unless WDG_SW bit it set? Is anyone aware ...

I think it is trying to add SW breakpoints, you need HW breakpoints in flash. So the drama here is about some F7 cores having bugs which cause openocd+eclipse to how work out of the box.
