Former Member
Former Member over 11 years ago

I connected riotboard via HDMI to different monitors with different physical resolutions and android started every time with an resolution of 640x480. How can I change this? Thanks for help.

    You should be able to change the resolution in u-boot mode passing the following arguments:

     

      MX6Solo RIOT U-Boot > setenv bootargs console=ttymxc1,115200 init=/init nosmp video=mxcfb0:dev=hdmi,1280x720M@60,bpp=32

    video=mxcfb1:off fbmem=10M vmalloc=400M androidboot.console=ttymxc1 androidboot.hardware=freescale

     

    MX6Solo RIOT U-Boot > saveenv

    I get an error message:  /system/bin/sh: can't create setenv: Read-only file system

    when trying to enter the command to change resolution.

    Please Help...

    if you are building uboot frequently on dev/test purposes, i would advice change the uboot params in board header file image

    for Riot its located at /uboot/include/config/mx6solo_RIoTboard.h  & mx6solo_RIoTboard_android.h  .
