Edge-V SWD degugging

Hello guys!

Has anyone dealt with swd debugging on edge-v?
I’m a mere software developer and complete noob with all the embedded hardware stuff, and I could use some help with setting things up.
I have segger jlink, and I made a microsd adapter.

Firstly, I cant even confirm that jtag port is working.
This dude here (https://crwulff.blogspot.com/p/rock64.html) sets the mux bits from uboot console, I tried that but no luck.
I also tried the maskrom mode (which I think enables jtag according to docs, but that might have been a mistranslation)

All I’m getting from j-link console is:
RESET (pin 15) high, but should be low. Please check target hardware.

which doesnt make any sense, because it’s swd mode.

Anyways, it’s a bit overwhelming and it’s hard to make sense of all the information. Maybe someone could point me to where I can read about how to set things up, or maybe someone even have a config file for jlink/openocd that works with 3399?
