Hi... I'm trying to build omapfbplay, but I'm getting this error
"ERROR: Please set the 'PERSISTENT_DIR' or 'CACHE' variable.". Does
anyone knows how to solve this? I'm using Ubuntu 10.10 and i have a
rev C7 board.

Thank you, I've managed to solve my problem. However now I have one
doubt. Is it possible to use bitbake to develop for Ubuntu ARM
version?

Q: Should I include quotations after my reply?

Thank you, I've managed to solve my problem.

How did you solve it?

However now I have one doubt. Is it possible to use bitbake to develop
for Ubuntu ARM version?

Please elaborate on what you want to accomplish. BitBake can compile
binaries and packages which you can use on Ubuntu. But the existing
recipes in OpenEmbedded might conflict regarding for example config file
locations in OpenEmbedded based distributions and Ubuntu.

Thanks,

Paul

It depends on what you are going to develop. ARM Ubuntu is the same Ubuntu as any other Linux is. The only difference is in a compiler: ARM Ubuntu uses ARM-gcc. So, you can develop you application at x86 host, debug it and then cross-compile it for ARM linux (Angstrom, Ubuntu, Gentoo or any other)…

I'm trying to build omapfbplay for Ubuntu, what settings should I use
in the config file?

Just another question. My beagleboard reports having 256MB RAM when
using the original u-boot.bin but when I use the u-boot.bin in the
Angstrom page it only reports 128MB. Is this normal? Should i use
another u-boot.bin?

Good question. I am no expert either. I guess you have to make sure that
the version of the libraries match. Otherwise I guess a lot of trial and
error lies ahead of you. :frowning:

Please open another thread on this topic. But I think to remember that
this has been discussed before on this list. But I am not sure.

Thanks,
