Hello William,
The board file use for this kernel are:
./am335x-arduino-tre.dtb
./am335x-base0033.dtb
./am335x-bone-cape-bone-argus.dtb
./am335x-bone.dtb
./am335x-boneblack-bbb-exp-c.dtb
./am335x-boneblack-bbb-exp-r.dtb
./am335x-boneblack-bbbmini.dtb
./am335x-boneblack-cape-bone-argus.dtb
./am335x-boneblack-emmc-overlay.dtb
./am335x-boneblack-hdmi-overlay.dtb
./am335x-boneblack-nhdmi-overlay.dtb
./am335x-boneblack-overlay.dtb
./am335x-boneblack-replicape.dtb
./am335x-boneblack-wl1835mod.dtb
./am335x-boneblack.dtb
./am335x-bonegreen-overlay.dtb
./am335x-bonegreen.dtb
./am335x-chiliboard.dtb
./am335x-evm.dtb
./am335x-evmsk.dtb
./am335x-lxm.dtb
./am335x-nano.dtb
./am335x-pepper.dtb
I still do not understand how I cannot boot properly off the uSD card on
the BBB?
I have used a 4GB uSD Class 10, and use the following command to format it
prior sending the kernel file, rootfs, modules.... I have first sent the
MLO and u-boot-dtb.img
sudo mkfs.ext4 -L rootfs ${DISK}1, one of the steo from Robert Nelson
eewiki to format a uSD card.
It is a bit enoying that I can't even clone another card to deploy on other
BBB card.
Can you advise how to solve this? I still do not understand why on BBG I
can boot without pressing the S2 button?
