Jack,

You can put a MLO, boot and rootfs on a card just as well as having it on the emmc...for Angstrom, thats what I do every day.

Hello all,

Here is what I have so far.

I need to use the GPMC features on the BBB, in order for me to do that, I have to boot from the microSD card because apparently according to the manual, GPMC needs the eMMC to be free.

So, I installed uBuntu 13.04 onto my SD card and I am booting from that (since Angstrom doesn't have anything that lets you boot from the system for the SD card).

Now the problem I have is how do I change Pin Mux in ubuntu? I know how to do that quite well in the Angstrom environment.

Your help is appreciated!

Jack

I boot from uSD on beaglebone and beaglebone black daily with angstrom, so I don't get what you mean with "doesn't have anything that boots from sd".

Which file do you use on your uSD?


This is the link that I use, but all those files are either for flashing eMMC or for Beaglebone and not Beaglebone black.

There's no difference between the images for beaglebone and beaglebone black, they all support both. So use the img.xz.

I tried that though, but problem that I had was that it didn't let me ssh to the board.

Did this happen to you? Or did you do something differently?

Which file did you put on your SD card? The flasher or the other one.

Make sure that you aren't sharing your network connection with your beaglebone.
