I hookup the usb to my (MX LINUX/Debian) desktop but i see no detection from PC? I also tried pressing the boot button..

[ntn888]

okay, i had to manually short boot pin with 3V like noted... the boot button doesnt work

When trying to flash the 'default firmware' file from examples I get following error:

How do I use use bluetooth with this?

[pgroon]

Ok, so literally none of this works. It never shows up as a USB device, neither on Windows nor on Linux. On Linux I followed the instructions for SDK setup. All seems good, but in the end it does not compile:

"fatal: ambiguous argument 'origin/release_v1.4.5': unknown revision or path not in the working tree."

So I tried the Bouffalo Lab Dev Cube instead. Again, all seems well. Software starts up, but there's no COM port. Instead, the board shows up as /dev/ttyACM0. I reboot the board with 3.3V and BOOT pins bridged, the screen stays white, but it's the same thing. I go to MCU tab, select "refresh", again it shows up as /dev/ttyACM0.

When I try to flash anything it actually starts and seems to go well, but then crashes:
