Android 4.2.2: unable to set 1920x1080 HDMI resolution

[fabiof]

Hi all

I'm working on the last Freescale Android version 4.2.2. My goal is to show Android on a HDMI monitor using 1920x1080 resolution but not able to obtain such result yet. I'm currently booting from SD u-boot using the following kernel command line:

console=ttymxc1,115200 init=/init video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24,bpp=32 video=mxcfb1:off video=mxcfb2:off fbmem=10M fb0base=0x27b00000 vmalloc=400M androidboot.console=ttymxc1 androidboot.hardware=freescale

The kernel load and start android but the monitor tell me that the signal is not correct and nothing show up. I checked and logged the mxc hdmi driver (mxc_hdmi.c) and activated the debug messages. Follow the log from dmesg:

Also other lower resolution doesn't work. It are days I'm working on this problem but no progress made.:-(

Someone can help me?

Thank you

You did forget to mention your board/chip.

Hi

Thank you for your reply. Fortunately just yesterday I was able to set resolution correctly. For all the people could exteriment a similar issue in my case it was something wrong into the kernel configuration file. I restarted from "original" definition file provided into Android package and make the required changes for my hardware and now HDMI video is working. I don't know which settings in particular was wrong however, but I'm not very interested in it right now. :smileyhappy:
