BUMP?

The following has been known to work, but as you've observed the -t support isn't in all releases.

echo "LOLOifconfig sm0 10.0.1.2 255.255.255.0 10.0.1.1;load raw 0x81000000 0x200000 /tftp/10.0.1.1:zImage.mx31;exec -t -i 447 -a 0x80000100 0x81000000 - \"console=ttymxc0 root=/dev/nfs nfsroot=10.0.1.1:/opt/L2618-1_mx31/ltib/rootfs rw init=/linuxrc ip=10.0.1.2::10.0.1.1:255.255.255.0 noalign\";exit;" /dev/config

Hello,

I'm not familiar with Lolo, so sorry for the newbie questions to follow :

- question 1 : is there any means to prevent Lolo to execute the config script in /dev/config ? I entered the script given by Paul in this thread (with the ip addresses and path matching my setup, of course), and since Lolo never shows up anymore, nore displays an error message. My NFS config may not yet work on sever side, i need to check that.

- question 2: could anyone kindly give the steps to burn the rootfs.ext2.gz ramdisk image generated by ltib into the flash, and what kernel options to give to set root (what is the device name) ?

thanks for any help you can provide

Marc.

I found the answer to my first question from the FAQ's at Logicpd's site :
press the 'q' key while reseting, to bring up Lolo and skip the script.

* *
* v0.1 - 07_31_07 - Initial release *
* *
* Logic Product Development *
*******************************************************************************

Overall steps:
1. Copy the rootfs to the /src/nfs/imx31_rootfs
2. Boot using NFS to write rootfs to NAND flash
3. Rebuild for NAND rootfs

*******************Build Steps***************

mount -t iso9660 -o loop logic.iso /mnt/logic (of course you can write it to CD)
cd /mnt/logic
./install (you will asked some install dir)
cd (install_dir)
./ltib

Clean all:
./ltib --mode distclean

Compile & build:
./ltib -l -s -f

*******************Rebuild Steps***************

./ltib --mode distclean
rm -rf rpm
./ltib -l -s -f

zImage can be found in the rootfs/boot/zImage

*******************Boot Steps***************
Assumptions:

- Development host running nfs and tftp server
- Logic Kit connected to development host over ethernet
- Development host IP: 10.10.10.1
- DHCP server available to assign IP to Logic Kit or assign manually in LoLo (not shown)

1. Create nfs and jffs2 images with ltib (modified for LPD board support).
Configure jffs2 for a 16kB erase block size.

2. Copy loader_nfs, loader_nand and zImage to tftp area.
cp rootfs/boot/zImage /srv/tftp
cp loader_nfs /srv/tftp
cp loader_nand /srv/tftp

3. Copy ltib rootfs to nfs area.
cp -a rootfs /srv/nfs

4. Start a terminal emulator (eg. minicom) at 115.2kbps to communicate with LogicLoader.
Enter the following commands:
losh> ifconfig sm0 dhcp
losh> load elf /tftp/10.10.10.1:loader_nfs
losh> load raw 0x81000000 1664580 /tftp/10.10.10.1:zImage (make sure for the proper file size)
losh> exec 0x800d0430 -

5. Erase nand flash:
imx31# flash_eraseall /dev/mtd/2

6. Write rootfs to flash:
imx31# nandwrite /dev/mtd/2 /home/rootfs.jffs2 -p (make sure for 16kB jffs2 erase block size!)

7. Reboot the board and now boot using the nand rootfs:
losh> ifconfig sm0 dhcp
losh> load elf /tftp/10.10.10.1:loader_nand
losh> load raw 0x81000000 1664580 /tftp/10.10.10.1:zImage (make sure for proper file size)
losh> exec 0x800d0430 -

Notes:

loader_nand: nand flash will be root fs will
COMMAND_LINE "console=ttymxc0 root=/dev/mtdblock2 rootfstype=jffs2 init=/linuxrc ip=10.10.10.2:10.10.10.1:10.10.10.1:255.255.255.0:imx31box"

loader_nfs: nfs will be the root fs
COMMAND_LINE "console=ttymxc0 root=/dev/nfs nfsroot=10.10.10.1:/srv/nfs/imx31_rootfs rw init=/linuxrc ip=10.10.10.2:10.10.10.1:10.10.10.1:255.255.255.0:imx31box"


Patch instructions:

copy the patch file into the /opt/freescale/pkgs directory and untar the other the user home.

Patch should have 6.4" Display support (untested by PC)

I'm glad to see that LogicPD is stepping up to the challenge of getting a stable Linux kernel running on their system. I just have a couple of quick question that this leaves unclear:

Which release from freescale is this applied to? (3?, 4?)
Is this patch file you speak of something that LogicPD provides? The loader files must be custom too? I don't see anything in the download section yet, but you did just post this.

Thank you!

Where or how did you create the loader_nfs and loader_nand?

you can use: http://mx31.lbox.ca/download/bootloader.tar.gz

or use the lolo -t option works great but it's a new feature so not in most versions.

Any ideas when a version of lolo will be released that supports the -t option? The latest version I've found in the downloads web page is still 2.3.5 from last May.

hai,

I followed the steps given but at step 4 the board is rebooting itself, it is not booting the zImage. what may be the problem?

Thanks in advance.

Try this as your last command in step 4:

exec 0x800d03a8 -
