So, today was an epic fail.
I try to work on the trimmer (potentiometer on my STM32 board). After considering datasheet a long time, and trying to implement how it works, there were still some parameters I did not understand. That is why I thought it would be appropriate to see an example, and so I decided to flash a ChibiOs ADC example on my board. That is how I lost my JTAG probe and my STM32…
I did not understand what had happened.
I lost several hours trying to reconnect my STM32. Now, that is done, and I understand that I lost hours for… nothing, because it was obvious since the very moment I lost my JTAG probe that it was because the ChibiOs board used in the ADC example do not allow JTAG use, and so, I have to reboot my board with the right configuration.
It is just…. I had forgotten one step : I had to keep two buttons pushed while I reload openocd and gdb.
Just Two buttons pushed. I am not very proud of myself, just now.I think I will keep on working on my STM32 tomorrow. I need some rest.
