Hi, Yes I have uEnv.txt file, but on Rev B all I needed was this:
optargs="consoleblank=0" capemgr.disable_partno=BB-BONELT-HDMI,BB-BONELT-HDMIN capemgr.enable_partno=BB-UART1,BB-UART2 Ok, so am I correct in assuming: uenvcmd=load mmc 0:1 /boot/zImage 0x.... ; load mmc 0:1 /boot/am335x-boneblack.dtb 0xxyz... ; bootz 0x - 0xxxyz translates to: uenvcmd=load mmc [device:part] /boot/zImage [load-address]; load mmc [device:part] /boot/am335x-boneblack.dtb [fdt-address]; bootz [load-address] which should become this..? uenvcmd=load mmc 0:1 /boot/zImage 0x82000000; load mmc 0:1 /boot/am335x-boneblack.dtb 0x88000000 ; bootz 0x82000000 My SD image is built for Rev B so it creates a uImage not a zImage. is this going to be an issue? I can re-build as zImage. or do I simply change to: uenvcmd=load mmc 0:1 /boot/uImage 0x82000000; load mmc 0:1 /boot/am335x-boneblack.dtb 0x88000000 ; bootu 0x82000000 One question, is the SD card mmc device 0? I assumed this would be the nand device, and hence I should be using mmc 1:1 ? Thanks for your help.
