SK-AM62: Vertical display from HDMI

Hello,

In HW, we do not have any rotation features so you need to reply on your window compositor. For example, weston has the transform feature and that's something you can explore.

Hello,
Did you boot Debian OS on SK EVM AM625?

I try to modify weston.ini "transform=90" degree, the HDMI display still no change...

I've tried both OS and it doesn't work.

Same, I've also tried to boot Debian OS from SD card, but the board is booting Android, which is present in eMMC of SK EVM AM625.
I cant get, why this happened

If you booted Android, you need to run the command env default -f -a.

I think your problem is from boot mode. change dip switch to sd/emmc boot. than board wiil boot from sd card.

But, while booting Debian OS, in the instructions given by Ti, we dont need to set any environment variables right?

I've tried it with SD card boot mode only. But it is booting up into Android

Did you run "env default -f -a" in Uboot?

Krunal

No, because in document provided by ti, it isn't mentioning for setting any environment for Debian.

Hello Aditya,

Did you load Android before loading Debian?

Krunal

Hello,

Yes I loaded Android into the eMMC of AM625, and Debian is in SD card.

Aditya

Okay, did you try env default -f -a and load again?

At first when I didn't tried it, it was booting Android which is in eMMC.
But, after giving "env default -f -a" in u-boot. It is saying that 
Bad linux image.

Can you check your SD card if those files are present or not?

Yes, I used BalenaEtcher to flash the Debian image and after flashing, I checked for all files and it was present
