Coldcard MK4 Stuck Boot, HSM Mode Used.
Currently I have a Coldcard that is now stuck while booting.
Steps to reproduce. 2. Enable HSM Mode 3. Plug into Dell R730 front usb port (left) 4. Device reboots many times in quick succession 5. Device halts and is bricked.
I believe this could be due to a power delivery issue.
