I´m using a wandboard Dual and I trying to display on the LCD screen the image I created with yocto project.
I'm using the following line in the bootloader:
video_settings=mxcfb0:dev=lcd,SEIKO-WVGA,if=RGB666 video= mxcFb2=off fnmem=8M gpumem=24M voutmem=48M vmalloc=200M
is that the only modification I´ve got to do or do I need to modify the kernel of my yocto image too. Because I run my image but it doesn´t display it on the LCD screen , it only turn on the screen.
These are the environment variables I'm using in U-Boot:
baudrate=115200
bootargs=console=ttymxc0,115200 root=/dev/mmcblk0p1 rootwait rw video=mxcfb0:dev=lcd,SEIKO-WVGA,if=RGB666
bootargs_nfs=setenv bootargs ${bootargs} root=/dev/nfs ip=${ipaddr}:${serverip}:${gatewayip}:${netmask}:::off nfsroot=${serverip}:${rp
bootcmd=run bootcmd_net
bootcmd_net=run bootargs_nfs; tftpboot ${loadaddr} ${kernel}; bootm
bootdelay=3
ethact=FEC
ethaddr=00:1f:7b:b2:03:8d
ethprime=FEC
gatewayip=192.168.1.1
ipaddr=192.168.1.102
kernel=uImage--3.0.35-r0-wandboard-dual-20131116024259.bin
loadaddr=0x12000000
netmask=255.255.255.0
rootpath=/home/beto/bin/fsl-community-bsp-dylan/build/tmp/deploy/images/rootfs_v2
serverip=192.168.1.1
splashpos=m,m
I modified the bootloader from an Ubuntu image that is on the wandboard web page, first I displayed the Ubuntu image on the LCD screen to make sure that I could use that bootloader, I did this by changing the bootargs variable from the original setup. The image shown has some kind of glitches.
Afterwards I used the same environment variables I've been using to boot using TFTP and NFS protocols. But the screen keeps apearring white!
