I bought an STLink V2 clone.
Installed STM32 ST-LINK Utility, connected the 4 wires to the SWD (J2) connector on the SKR 1.4. The Diode (labelled D4 on SKR 1.3) is illuminated when I connect the ST-Link Adapter. However I cannot get it to connect with ST-Link Utility. I tried all the different connection modes and also varied the connection frequency.
When I connect the STLink adapter to the ICSP header on my SKR1.3 I can at least get the status LED on the adapter to blink blue instead of red for a couple of seconds, the ST-Link utility also detects the target as 3.3v. However, the connection still fails.
In PlatformIO I cannot select stlink as an upload_protocol as I get unknown upload protocol error. When I edit the config files for lpc1768 in my user config directory to add stlink to the supported upload protocols I still get unknown protocol.
I still have a FTDI 232H adapter, an original intel USB Blaster II and an Arrow USB Programmer. I mean some adapter has to somehow work…
