[SOLVED] Console Port

dpitchfo

I am unable to get the UP Square to redirect the output to the console port. I can get to the bios screen, but then when it boots, I get the following error:

OS: Ubuntu 16.04 Server

**error: no suitable video mode found.
Booting in blind mode
**
I have modify my /etc/default/grub file and added the following:

**GRUB_DEFAULT=0
GRUB_TIMEOUT=2
GRUB_DISTRIBUTOR=lsb_release -i -s 2> /dev/null || echo Debian
GRUB_CMDLINE_LINUX_DEFAULT="text"
GRUB_TERMINAL="serial console"
GRUB_CMDLINE_LINUX="console=tty0 console=ttyS0,115200n8"
GRUB_SERIAL_COMMAND="serial --speed=115200 --unit=0 --word=8 --parity=no --stop=1"
**

BIOS:
Version: UP-APL01 R3.3 (UPA1AM33)(01/17/2018)

I have also set the bios:
Advance > Serial Port Redirect > Console Redirection [Enabled]
Advance > Serial Port Redirect > Out-of-Band manager > Console Redirection [Enabled]

I have tried a hundred of post and with no luck. Can anyone give me some advice.

Thanks

Hi @dpitchfo ,

Did you try the Ubuntu serial port instructions for UP2?

Your BIOS looks like up to date...

Cheers!

Yes, I tried these instructions. I get the BIOS screen, but when boots, I get the video error.

Hi,

You could try to test your UART serial console port maybe using the Linux Serial Test to confirm your UART is not working:

Found this post. My configuration are correct, the issue is on the UPSQUARE, the console port is ttyS4 not ttyS0. Once I changed that, its working. See:

Oh yes,

ttyS4 and ttS5 are availble for UPSquared.

Thanks!
