Can't Boot Qtopia from microSD
Hi,
If someone has Qtopia (or any other distro, for that matter) booting
from microSD, I'd appreciate very step-by-step instructions, because it
is not working for me and I have poured over the wiki's various pages
related to this. Here's what I've done:
1. Partitioned my 8GB microSD card thus:
partition1: FAT32
partition2: ext2
partition3: ext2
partition4: ext2
each partition is roughly 2GB.
2. partition2 is where I want to put Qtopia.
After formatting it ext2 and mounting the partition, I did:
wget http://qtopia.net/downloads/neo/qtopia-4.3.2-gta02-flash-07221045.tgz
tar zvxf qtopia-4.3.2-gta02-flash-07221045.tgz
mv uImage*.bin uImage.bin
I changed the kernel name based on something I read stating it had to be
called uImage.bin (is that wrong?)
3. I upgraded my NAND U-boot to a post-July 23 version. I think I have
the August 5 version now.
4. I edited by NAND U-boot menu to include:
setenv menu_9 Boot from microSD part2 (ext2+ext2): setenv bootargs
\${bootargs_base} rootfstype=ext2 root=/dev/mmcblk0p2 rootdelay=5
\${mtdparts} ro\; mmcinit\; ext2load mmc 1 0x3200
\${sd_image_name}\; bootm 0x3200
5. I try to boot from that new NAND U-boot option and while the error
page goes away so fast I cannot really read it, by doing it dozens of
times, I think it cannot even mount the ext2 partition, and thus cannot
find a kernel image. I get shot back to the U-boot menu right away.
Thanks for any help. If I figure all this out, there is going to be a
single crystal clear wiki page on this when I get done.
Brian

It needs to match whatever you called it on the kernel commandline in
U-Boot, our ones use uImage.bin.

Great.
| 4. I edited by NAND U-boot menu to include:
| setenv menu_9 Boot from microSD part2 (ext2+ext2): setenv bootargs
| \${bootargs_base} rootfstype=ext2 root=/dev/mmcblk0p2 rootdelay=5
| \${mtdparts} ro\; mmcinit\; ext2load mmc 1 0x3200
| \${sd_image_name}\; bootm 0x3200
Ignoring the menu stuff for a moment, here is a canned one liner to do
something like what you want
setenv bootcmd mmcinit \; ext2load mmc 2 0x3200 uImage.bin \;
setenv bootargs \${mtdparts} rootfstype=ext2 root=/dev/mmcblk0p2
console=ttySAC2,115200 loglevel=4 init=/sbin/init \; bootm 0x3200 ; boot
Notice on ext2load the first number is the partition index it should
use, counting from 1.

Download qtopia-4.3.2-gta02-flash-07221045.tgz from: http://wiki.openmoko.org/wiki/Latest_Images#Qtopia_image_from_qtopia.net It extracts to: qtopia-4.3.2-gta02-flash-07221045.jffs2 uImage_2008_07_16_gta02_73eeb0333fc771cb696ff9bf17c517c741434b59.bin 2. Prepare SD card (from USB 4-in-1 card reader): fdisk /dev/sdb First partition is 8M. Use remaining disk space for second partition. 3. Create vfat on /dev/sdb1 mkfs.vfat /dev/sdb1 Rename the uImage kernel to uImage.bin and copy it to the first partition. 4. Create ext2 filesystem on /dev/sdb2 mke2fs /dev/sdb2 5.

Minor correction - the parameter for ext2load and fatload is
device:partition, so partition 2 would be ext2load mmc 1:2
IIRC this is documented in the online help for fatload but not for
ext2load.
For troubleshooting you can also run mmcinit; ext2ls mmc 1:2 / from
the u-boot console to make sure that u-boot is able to access the
partition, and to see what files are on the card. There is also a
fatls command to look at a VFAT partition.

Re: Can't Boot Qtopia from microSD
of them come back FATAL no such module, like so: [EMAIL PROTECTED]:/mnt/qtopia# modprobe mtdcore FATAL: Module mtdcore not found. [EMAIL PROTECTED]:/mnt/qtopia# modprobe jffs2 FATAL: Module jffs2 not found. [EMAIL PROTECTED]:/mnt/qtopia# modprobe mtdram total_size=59024 FATAL: Module mtdram not found. [EMAIL PROTECTED]:/mnt/qtopia# modprobe mtdchar FATAL: Module mtdchar not found. [EMAIL PROTECTED]:/mnt/qtopia# modprobe mtdblock FATAL: Module mtdblock not found. every one of these is probably not part of a standard variety installation. have a look at google to find out what packages of your distribution contain these modules. ___ support mailing list support@lists.openmoko.org https://lists.openmoko.org/mailman/listinfo/support

My mistake, I just edited my canned one I use for first partition off
the top of my head. One way or another personally I only ever pulled
kernel from the first partition on SD Card myself, VFAT or EXT3.
