I found the post where I documented what I did. I did this in Linux, not windows, but here is what I did:
Yes, there are a lot of fake ST-link units out thereā¦ I ordered one and ended up with something that is basically just a usb-ttl adapter ( like you have), a genuine st-link has swclk, swdio, swim, rst, gnd, 3v3 and 5v0. Iām sure most of the Chinese sellers donāt understand there is a difference!
Great news, it appears to have worked. I flashed the bootloader and then was able to see the card via usb and once I flashed the marlin firmware the TFT was able to see the printer as well. Now I have to rewire up the stepper motors and the endstops as I had taken everything apart to try to figure it all out. Thanks Mike and Jeffeb3 for all the help. Hopefully all will go smoother from here on out.
That is great news. I wonder how it got messed up in the first place. But I am happy it is cruising now.
Did you use the uart, it wait for the stlink?
I got the st-Link and it all worked like a charm, 'cept had to bum my sonās windows computer to get it to link up. Mac running windows in parallel didnāt cut it.
Ugh. So sorry about the wrong item. Iām also having the same issue now with my replacement board that says no printer attached. Will follow above.
