Re: Debugging MicroRusEFI, can't connect openocd

Ok, I've gotten a nucleo board at work, and it has an embedded STLink. Will there be issues connecting it to the microRiusEFI? My concern is that when I was using the ftdi breakout, its vdd sat at 5V and could power the microRusEFI target. However the actual STLink is at 3v3, and can't power the boa...

The weather is nice, I can't complain. I managed to reach the other engineer who was working on this. I don't think he configured a dashboard. I have an oscilloscope, I could try to do this and probe the output. Are there instructions to do this? I'm not so familiar with the project, sorry if this i...

Re: Debugging MicroRusEFI, can't connect openocd

That's kind of what I figured. Unfortunately this was the only thing my boss had on hand, and he's already asking me for results. At a high level it should behave the same, but this appears not to be the case. Would this approach work if I connected an ST-Link to these pins and changed the invocatio...

I've been tasked with connecting a debugger to the MicroRusEFI that my team has purchased to step through the firmware. I'm able to flash the firmware, but when I try to connect a debugger using openocd I recieve the error Error: Error connecting DP: cannot read IDR I'm connecting to the SWD connect...
