Dual boot nand-sd almost there..

[msalmon69]

I did my homework. I upgraded my sheevaplug to denx u-boot, run the installer following the instructions at http://www.cyrius.com/debian/kirkwood/sheevaplug/install.html

To reboot I sort of used:

Code:

setenv bootargs_console console=ttyS0,115200
setenv bootcmd_mmc 'mmc init; ext2load mmc 0:1 0x00800000 /uImage; ext2load mmc 0:1 0x01100000 /uInitrd'
setenv bootcmd 'setenv bootargs $(bootargs_console); run bootcmd_mmc; bootm 0x00800000 0x01100000'

I say 'sort of' because I think I had to enter those commands one by one but anywaythey worked the 2nd time around.

I have now a full Debian Squeeze LAMP stack on my 16GB SD card and all my apps work fine.

However I want to setup a dual SD/NAND boot w/out the risk of bricking my plug and I need help! As usual if the SD card is not there the plug should go with the NAND.

Looking somewhere in this forum I could see that

Code:

bootargs_console=console=ttyS0,115200
bootargs_root_mmc=root=/dev/mmcblk0p2 rootdelay=5
bootcmd_mmc=setenv bootargs $(bootargs_console) $(bootargs_root_mmc); mmcinit; ext2load mmc 0:1 0x800000 /uImage; bootm 0x00800000
bootcmd=run bootcmd_mmc; run bootcmd_nand

would do the trick. I know close to nothing about all those u-boot commands and I wonder if someone can help me "merge" these boot commands with mine (at the top)?

Thanks

I think that if you want a dual boot, you would see this topic:

http://www.newit.co.uk/forum/index.php/topic,194.0.html

I hope it could help you!

[msalmon69]

I have looked at about all the pages that relate to dual boot of this forum and some others too.  What I need is some specific help, if at all possible to merge the 3 sets of u-boots commands I listed to obtain one that will work without failing (bricking)

On the other hand if you guys,expert with the sheevaplug believe I have no risk bricking my unit, I am ready to do all kinds of tests on my own.

Thanks

[d_strigaro]

I'm not an expert of sheevaplug, but i had some adventures with it .
For this reason, i'm not responsible if i'll tell you some wrong advices that could brick your plug!!!

I think that if you set your u-boot like it is well explained in the topic that i post you everything could go on well, because i read that the first boot is set on the sd card and only if it is not present there will be the boot from nand memory.

Excuse me for my english but i'm italian.

[msalmon69]

Thankd d_strigaro, but what I really need is for someone to validate myspecific settings as described in my 1st post. I also would be interested to know if there is a way to find the file type w/out having to get to the marvell prompt. Thanks.

[msalmon69]

No taker?

[Confusticated]

if there is a way to find the file type

Please elaborate, I do not understand what you mean by 'file type'

[msalmon69]

By file type I means UBIFS of JFFS2

Thanks

[msalmon69]

May be I should re-phrase the question?

I have:

Code:

setenv bootargs_console console=ttyS0,115200
setenv bootcmd_mmc 'mmc init; ext2load mmc 0:1 0x00800000 /uImage; ext2load mmc 0:1 0x01100000 /uInitrd'
setenv bootcmd 'setenv bootargs $(bootargs_console); run bootcmd_mmc; bootm 0x00800000 0x01100000'

which allows me to boot my sheevaplug from a (probably) JFFS2 SD created while folloing the instructions at:

http://www.cyrius.com/debian/kirkwood/sheevaplug/install.html

I think my original sheevaPlug NAND hasn't changed. From there, what do I need to do to create a dual SD/NAND boot, meaning if the SD card is not in then the plug boots from the original NAND boot?

Thanks again.

[d_strigaro]

Could you post your settings that appear with the command 'printenv'?

[msalmon69]

Here are the original settings:

Here are the settings after migrating to Debian using the "installer":

What I added to be able to start from SD (I haven't tried yet to boot from NAND):

setenv bootcmd_mmc 'mmc init; ext2load mmc 0:1 0x00800000 /uImage; ext2load mmc 0:1 0x01100000 /uInitrd'
setenv bootcmd 'setenv bootargs $(bootargs_console); run bootcmd_mmc; bootm 0x00800000 0x01100000'

Thanks

If i were you i would do this steps:
1- save your u-boot settings because in case will be something wrong  you know how to boot your sheevaplug and the point where you could restart;

2- i try to set u-boot as in the topic that i posted you.

But i think that you don't know how to do it!

Your 'printenv' must appear in this way:

Code:

arcNumber=2097
autoload=no
baudrate=115200
bootargs_console=console=ttyS0,115200
bootargs_end=:::DB88FXX81:eth0:none

bootcmd_mmc=setenv bootargs $(bootargs_console) $(bootargs_root_mmc); mmcinit; ext2load mmc 0:1 0x800000 /uImage; bootm 0x00800000
bootcmd_nand=setenv bootargs $(bootargs_console) $(mtdpartitions) $(bootargs_root_nand); nand read.e 0x00800000 0x00100000 0x00400000; bootm 0x00800000

recover2=run recover3; setenv bootcmd $(real_bootcmd); saveenv; setenv bootargs $(bootargs_console) $(mtdpartitions) root=/dev/ram0 rw ramdisk=0x01100000,8M install_type=nand; bootm 0x00800000 0x01100000
recover3=run recover4; nand erase clean 0x00100000 0x00400000; nand write.e 0x00800000 0x00100000 0x00400000

stderr=serial
stdin=serial
stdout=serial
usb0Mode=host
vxworks_en=no
yuk_ethaddr=00:00:00:EE:51:81

so you would do this for every settings:

Code:

setenv arcNumber 2097
setenv autoload no
ecc..

You must notice that i don't write the '=' this is the way to set it.
For 'ethaddr' you must put the macaddress of your sheevaplug.
For 'ipaddr' you must put the address that you sheevaplug have in your network (you can see it in the settings of your router if you have it)
For 'serverip' you must put the network address of the pc where you are doing this steps.

After this you could save this setting with:

Code:

saveenv

Thid command saves the settings! If you don't do this after the first reboot you will have the settings that you have from the point where you start!
Than you can boot your sheevaplug.

Excuse me for my english it is difficult to explain it because i'm italian.

P.S.
For these two setting you must write in this way:

Code:

setenv bootcmd_mmc 'setenv bootargs $(bootargs_console) $(bootargs_root_mmc); mmcinit; ext2load mmc 0:1 0x800000 /uImage; bootm 0x00800000'

setenv bootcmd_nand 'setenv bootargs $(bootargs_console) $(mtdpartitions) $(bootargs_root_nand); nand read.e 0x00800000 0x00100000 0x00400000; bootm 0x00800000'

PLEASE NOTE THAT:

I'm not an expert of sheevaplug, but i had some adventures with it  .
For this reason, i'm not responsible if i'll tell you some wrong advices that could brick your plug!!!

In any case if your sheevaplug is good and you can use it i don't know why you want to do this.
