Hi Enrico,

All I did to build it, was to add meta-ti to my bblayers.conf and try bitbake with MACHINE=pandaboard. The build was screaming about some QA errors, which I had to disable to get
the build finish. I'm assuming those are the reason for my failure. However, I did not investigate further into these.

Break into U-Boot during the boot process and show us what you get from
the 'printenv' command.  This will show the default value of 'bootargs'
which is what is being used since you don't have a 'boot.scr' script

Panda # printenv
baudrate=115200
bootcmd=if mmc rescan ${mmcdev}; then if run loadbootscript; then run bootscript; else if run loaduimage; then run mmcboot; fi; fi; fi
bootdelay=3
bootscript=echo Running bootscript from mmc${mmcdev} ...; source ${loadaddr}
console=ttyO2,115200n8
loadaddr=0x82000000
loadbootscript=fatload mmc ${mmcdev} ${loadaddr} boot.scr
loaduimage=fatload mmc ${mmcdev} ${loadaddr} uImage
mmcargs=setenv bootargs console=${console} vram=${vram} root=${mmcroot} rootfstype=${mmcrootfstype}
