I'm trying to make my fresh new beagleXM work.
Until now I got the Angstrom distro working, but I have lots of
problems with the serial port.
I tried with:
- A USB/Serial adapter
- Another USB/serial adapter
- A serial cable (no null modem) with a native serial port
It seems like I'm having ground issues. The serial shows the linux
boot messages and I can come to the login prompt, but 70% to 80% of
the characters are wrong and it's really impossible to work with.
Serial settings are correct, but I always get these wrong characters.
Do I have to ground the board in another way (maybe through the ground
pin?) or maybe extract only the tx, rx and gnd pins from the serial?
I'm quite confused... and I don't have an oscilloscope
