Hi Adam,

I assume you see the text from the bootloader in some serial console=20
terminal until the kernel boots.  I used 'picocom /dev/ttyUSB0 =96omap=20
delbs =96baud 115200', and when the boot prompt is displayed ('boot:'), I=20
entered 'lts console=3DttyS0,115200'.  This enables the serial console=20
with the correct baud rate.  Be sure to also append this in your=20
syslinux.cfg before rebooting, or else append the same parameter to the=20
boot command line again.

I hope this helps.

Best regards,
Florian
