Checking the configs for supported OMAP boards, not one defines CONFIG_LCD: $ grep CONFIG_LCD `grep -l OMAP include/configs/*` | wc -l 0 As an example the MPC823 LCD controller is supported: $ grep CONFIG_LCD `grep -l MPC823 include/configs/*` | wc -l 25 I fear that you will need to implement support for the LCD controller yourself.

I find source from tools/env very useful (I try to get variables from correct file I already have), but I can't find any description of environment file (or flash partition) at all (which I need to write tool for generating environment file). Can someone explain me the structure of the file, please. Something like: 0-4 - CRC Well the problem is that environment can be in a different format, depending on configuration options. If for example you enable redundand environments, you will have another byte after the crc signalling which of the two copies is the active one. 5-... - (Environment)\0(Environment)\0... ... Environment End Mark... and so on. Or tell me in what file should I see from U-Boot source. A good start would be to read /include/environment.h - but only after you are really sure that you want to generate an environment after all :) : And is there any difference between content of OneNAND flash environment-partition and file on SD card?
