Display issue after selecting grub menu

[nemesis9]

Background: I have built the flashfiles option successfully and ran celadon on my NUC

Problem: When I build the img version and dd to my USB stick, it boots the NUC to grub, but then fails. My monitor displays nothing or just gives an error saying the timing is not supported.

What I have tried: I have tried to edit the linux kernel command line from grub, specifically the vga options, but nothing I have tried has worked (for example, vga=792).
I have also tried replacing vga option with resolution option, but this did not work either.
I have also tried all of the grub menu options.

Info: The NUC version is NUC7i5BNH.

Brown: This is a known issue after we upgrade to kernel 4.19.x. If you has a serial port (Use FTDI USB serial port convertor), then you can get the info from serial port. BR/Tan Ming.

Hi Ming, For NUC, I wonder where I could find the serial port. Can you point out?

Mustamin: For KBL NUC 7i5DNH, you can connect a serial port cable using https://www.gorite.com/serial-db9-header-cable-for-nuc-dawson-canyon. For APL NUC 6CAYH, since the board has not serial port, so we can use a USB serial port convertor which use FTDI chip. But use this way, the log is only available after the USB serial port driver is loaded. If you use the cel_apl lunch target, the default setting is use ttyUSB0 for serial port now. BR/Tan Ming.

Ok, I set up my USB-Serial device, but I don't see output on my terminal client. What is the baud rate I should use?
Also, could be it is crashing before it sets up the serial output?

[nemesis9]

I booted the NUC with ubuntu LIVE usb and tested my serial connection to make sure it works.
But when I boot celadon and select Serial Debug option from grub, I see no serial output, so it looks like it is crashing before it writes to serial port.

Brown: What is your hardware platform? And which lunch target are you using? If the kernel crash before it write to USB serial port, then you can’t get the log. BR/Tan Ming.
