i.MX53 and MCIMX-LVDS1 display kit

[jill]

I have a i.MX53 board which is currently being used with a VGA display. I want to set it up to use a LVDS1 display instead.

According to the quick start guide we are supposed to enable the LVDS output using U-Boot. Is U-Boot already installed along with the Ubuntu that comes with the 4 GB Micro SD card or do I have to install it myself?

I think it is already set up to output through LVDS.

You need to modify the booting arguments to send the output to LVDS instead of VGA.

Please take a look at the user guide to modify the arguments to use LVDS (attached)

Best regards,
Sergio

Thank you for your reply.

I've already read the user guide. My doubt is whether I'll have to install U-Boot myself or if it is already preinstalled on the provided micro SD card (which contains Linux).

I'm asking this because I have limited access to the board. If I have to install U-Boot I'd like to know beforehand so that I can be prepared for it. If it's already installed and I only have to change the booting arguments then that's easy. An additional question, to change the booting arguments do I need to connect to the board using the serial cable (RS-232)?

Hi Jill,

U-boot is already installed on SD card. Yes, to change the booting arguments, you need

to connect PC to the board with the serial cable (RS-232).

Hi,

Do you know if it is possible to change the U-Boot variables without the serial cable (RS-232)? For example, directly from the Ubuntu that comes pre-installed on the SD card.

Thanks!

I don't think it is possible.

What is the issue on getting a serial cable? ;-)

[jill]

Oh, my computer doesn't even have a serial port! :smileyconfused:

[fabio_estevam]

Mine doesn't as well. You can get a USB to serial adapter :-)

Good idea, thank you!
