RE: Booting Linux from UEFI on Beagleboard Qemu

Hi Olivier: Thanks, I have also forwarded to the EDK2 mailing list.

Cheers, Alan C

Hi Alan, I tried last night the build I recommended you (rev12160) but it did not work. I did a couple of additional fixes to make it work. I had the same Linux kernel crash as you are seeing. I will let you of any updates.

It should be better to speak UEFI EDK2 specific issue on the edk2 mailing-list: edk2-devel@lists.sourceforge.netmailto:edk2-devel@lists.sourceforge.net

Thanks for the feedback, Olivier

Hi Olivier: Thanks for the update. I did a svn update (now at r12175) and tested it again:

1. It now indeed booted in Linux and I got the following error during Linux booting: Uncompressing Linux... done, booting the kernel.

So, the MMC fix is probably in the right direction, but I think there are other fixes that may interfere. There were quite a few files that got changed and I actually have to fix a few typos in order to make it compile. I will try r12160 instead.

Thanks, Alan

Hi Alan,

What you did seem correct. I have not tried to duplicate the issue. But interestingly, I found a bug around the MMC driver using GCC to build the BeagleBoard UEFI firmware (the firmware was crashing when booting Linux). I fixed the bug in the revision 12160. It could fix the bug you found.

Thanks, Olivier

Hi all: I just started to play around with ARM UEFI stuff and has issue booting into Linux when trying to test the EDK2 software on Qemu. This seems like the right place to ask. I followed the instruction in (http://edk2.svn.sourceforge.net/viewvc/edk2/trunk/edk2/BeagleBoardPkg/readme...) including downloading the specific version of binaries / tools. When trying to run UEFI (both in NOR flash method as well as SD card method), UEFI started successfully. However, I kept on getting "Did not find Linux kernel" error when trying to boot Linux. From EBL, I can see the zImage file is present (cd fs1:; dir). The zImage file is basically vmlinuz-2.6.35-1008-linaro-omap from the hwpack. I even tried to extract zImage from uImage, but the result is still the same.

I am wondering if anyone has run into the same issue and can give me a hint on what else to try.

Thanks,

Alan Chuang
