I have a very weird issue with the SD card slot when I’m connecting the jtag debugger.
Debugging itself works just fine, I’m able to use GDB and all.
The problem is that the connection is only stable when the cable is only partially inserted into the slot.
I have to very carefully wiggle it in so that it only barely touches the pins in the slot.
I I do a full insertion with a click - nothing works.
And the cable position where everything works is very consistent. So it’s not that big of a problem. I’m able to debug just fine. I just want to understand what could be going on.
I have little experience with hardware, so maybe I’m missing something.
I’ve tried 2 different types of sd card adapters, and it’s all the same problem.
I’ve tried it with and without a pull-up resistor (on the swdio channel). And I’ve tried different power sources.
Is there anything I can try? Does this sound like a familiar issue to anyone?
