Bertl: I would be down for a short session now

yes, as long as you do not want to change the pixel clock

or is there another pll involved?

in theory you can reconfigure that on the fly, but it's tricky

okay

yes

now I want to have the hdmi output on one port only and play around with the video timings

the relevant parts for setting up the HDMI output image are the gen_init.sh script which configures the timing, the data_init.sh which adjusts the data timing and events and the ./rmem_conf_bin.sh which configures the read address generator

./gen_init.sh 1080p60

./data_init.sh

./rmem_conf_bin.sh 64 228 2048 1920 1080

the magic variables here are the offsets H=64 and V=228 in the 4096x3072 frame

you can then load a test image with mimg like this:

here -F means for 'frame' buffer 0, -L is the row length, -W and -H the image sizes and -T4 is the color test image

you can configure that with

scn_reg 31 0x4000

you should then get a nice color gradient as output

okay my network setup is falling apart and i have to acknoledge that I am to tired for this

good night!

anuejn: please document the commands and what you learned so far somewhere (wiki, etc.) from Bertl
