Beagle Bone Black support

I have that one (look @ topic) and I am wondering what is a status an ARM port on those
device. I run a img hrev53652-arm-mmc and seen this log (by UART)

And seen everyware a LINUX. A don’t understand bootloader try to load Kernel and Black Bone switch up to Flash memory and load debian from chip?

2 Question. How emulate Black bone on qemu (they don’t support BBB).

So yes, the uenv on the SD card does not seem correct.

As for the status, well, this has not been tried in a while and, as far as I know, not since kallisti5 changed the image generation to build a single SD image that should (ideally) boot on all ARM devices. So this will have to be fixed so a proper uboot env is provided and used to load our kernel.

For qemu, there is a fork that support the beaglebone here: https://launchpad.net/qemu-linaro

Thanks for fast response. It;s my fault my log is from eMMC (where bin linux) from BBB not from SD Card. I try tomorrow play with Haiku ARM.
