Help with st-link

BennehBoy Fri Jan 27, 2017 11:25 am

I managed to brick one of my maple mini clones when attempting to use victors firmware updater sketch.

I bought an st-link2 clone which arrived today.

I’ve connected ground to ground on the mini, reset to reset on the min, SWCLK to pin 21, and SWDIO to pin 22

I then powered the Mini only by USB (so not 3.3v connection from the st-link2 clone)

The st-link utility reports the following:

11:23:49 : Can not connect to target! Please select "Connect Under Reset" mode from Target->Settings menu and try again. If you're trying to connect to a low frequency application , please select a lower SWD Frequency mode from Target->Settings menu. 11:23:50 : No target connected

Should be a way to use this method -> https://github.com/rogerclarkmelbourne/ … from-Linux

But it will need a different config for the ch340 usb to serial…

So this line:

while true; do openocd -f /usr/local/share/openocd/scripts/interface/stlink-v2.cfg -f /usr/local/share/openocd/scripts/target/stm32f1x.cfg ; sleep 1;done

Would need to look something like:

while true; do openocd -f /usr/local/share/openocd/scripts/interface/ftdi/ch340.cfg -f /usr/local/share/openocd/scripts/target/stm32f1x.cfg ; sleep 1;done

I’m trying to find a suitable config though.

Can someone repost to this thread, as I need to check the cacheing

This could be why I had problems using the python script to do the flashing on linux -> https://sourceforge.net/p/stm32flash/wiki/Hints/

This is a test post. I will delete later to test the server caching issues
