Hello,
i have some board with iMX6Q
There i have the U-boot menu.
By default systems start with this parameters:
setenv bootargs console=ttySAC0,115200 init=/init video=mxcfb0:dev=ldb,LDB-1080P60,if=RGB24,bpp=32 ldb=spl0 video=mxcfb1:off video=mxcfb2:off fbmem=48M vmalloc=400M androidboot.console=ttySAC0 androidboot.hardware=freescale
i trying to change the LVDS output from 24bit to 18bit.
It's mean i need to change RGB24 to RGB666.
setenv bootargs console=ttySAC0,115200 init=/init video=mxcfb0:dev=ldb,LDB-1080P60,if=RGB666,bpp=32 ldb=spl0 video=mxcfb1:off video=mxcfb2:off fbmem=48M vmalloc=400M androidboot.console=ttySAC0 androidboot.hardware=freescale
Next step: saveenv
i see this:
Saving Environment to MMC...
Writing to MMC(3)... done
Right?
but on next step i run Boot, and in log i see it's run with default parametrs RGB24. it's mean not saved my parametrs. Why so?
Next step: boot or run bootcmd
How to change this parametrs? why his not saved the new parametrs?
And another quastion:
There i have boot menu
[1]boot from emmc
[2]boot from sdcard
[3]boot from tftp
[5]download from sdcard
[0]setting boot args
[q]exit to command mode
Enter your selection:
How to change thismenu and parametrs?
Thank's lot,
Andrey
