Bosean FS-5000: Cannot flash

[ricsim]

I have 3 devices. Fnirsi GC-1 with WCH, that i just updated to 2.0rc5 with STLink. Another GC-1 that I updated with the bootloader drive. And a Bosean FS-5000 where I get the error below. (Pinout is different than GC-1, but I rearranged the pins.) Any ideas?

Here is a picture, on the picture one of the pins slipped out, but it was connecte when I tried to flash: https://menedetter.net/bosean.png

tried it again and made sure all 4 pins are connected: Backing up old firmware image... xPack Open On-Chip Debugger 0.12.0+dev-01557-gdd1758272-dirty (2024-04-02-07:27) Licensed under GNU GPL v2 For bug reports, read http://openocd.org/doc/doxygen/bugs.html Info : auto-selecting first available session transport "hla_swd".

What happens if you keep the ok/power button pressed while flashing?

[ricsim]

Many thanx!! That worked, I am running RadPro now!! Yeah ;)

Will update the docs.

I do not have a serial port over USB. Windows shows no USB device, and also Linux does not show anything in dmesg, when i plug in the USB cable. GC-01 with the same cable works fine.

Please open another issue.

Also, make sure you copy the backup in the backup folder to a safe place.

Strange, it seems to have been a one off. Today it works perfectly! Thank you so much for the FS5000 support.
