those wires look too long and too loose. you will need to shorten them for sure and tighten them up a big
shorter is better, keep it as short as possible
edit do you mean 8inches and not 8cm? 8cm is the length of the rpi board

They were actually 10cm, now they are closer to 4. :-)

Unfortunately wasnt the (root) cause of my issues.

Fyi to clear this up I was able to fix it. It likely wasn't a remora-based issue

please refer to.

That said I'm still on a 2024 commit with my current setup, as it seemed more resilient in regards to SPI Comms on F103, but i'm pretty sure upstream would work too.
