Hi,
https://bugs.launchpad.net/ubuntu/+source/linux-ti-omap4/+bug/633227
seems to suggest we can now use 1GB of RAM on a Panda board.
Creating a new image using the following images and hwpacks for my Panda :
BOARD=panda linaro-media-create --rootfs ext4 --mmc /dev/mmcblk1 --binary linaro-n-developer-tar-20110426-0.tar.gz --hwpack hwpack_linaro-panda_20110426-0_armel_supported.tar.gz --dev panda
I see that :
root@linaro:~# uname -a Linux liliput-panda 2.6.38-1002-linaro-omap #3-Ubuntu SMP Fri Apr 15 14:00:54 UTC 2011 armv7l armv7l armv7l GNU/Linux
root@linaro:~# free -m total used free shared buffers cached Mem: 662 538 123 0 14 494 -/+ buffers/cache: 30 631 Swap: 0 0 0
Is there something else that I'm missing here ?
cheers Ramana

This bug has been marked "fix released" for linaro-image-tools, but there has not been an update of linaro-image-tools in Ubuntu natty since February. If you use linaro-media-create from the bzr branch when writing to the SD card, you should see more memory available.

I am using linaro-media-create from the PPA - given that my host is a Maverick system and this was updated to this mornings version which appears to be 0.4.4
Please note that the cmdline I have at the minute has the following line :
mem=456M@0x80000000 mem=512M@0xA0000000
Thus I would expect there to be atleast 968M of RAM rather than just 662M !

Not sure why I seem to have very different kernel cmdline in this case.

Ok based on a conversation that Marcin and I had on IRC , it turns out that the kernel I'm running is a linux-1002-2.6.38-omap4 kernel while Marcin is running a 1024-2.6.38-omap4 kernel ? Why is it that the daily hwpacks either from haven't been updated with a kernel after 1002 in this case ?
