Re: U-Boot for Nokia RX-51 with BootMenu
 

Have the same here. Details:

1. 1. Have the healthy FAT at /home/user/MyDocs
2. 2. U-boot shows default menu
3. 3. U-boot console:
   
   Code:

   ---

   mmc init
mmc dev 1
fatls 1

   ---

   It shows the contents of /home/user/MyDocs/Text/0scraps/20111026223145

So U-boot indeed handles (v)FAT incorrectly.
My guess it is due to misaligned partition OR parted resize. I mean I used parted to resize /dev/mmcblk0p1 so that I could put another system on eMMC.

Any ideas howto fix?

Re: U-Boot for Nokia RX-51 with BootMenu
 

when creating the bootmenu.d file entry for the latest Nemo kernel, what extra boot arguments/options one needs enter in the file to boot Nemo from the SD card ?

or, what manual commands could be tried in the uboot console to boot nemo ?

stskeeps would be the best to answer this I guess, as he was the first person able to create the PR1.3+uboot kernel, able to boot from the external MMC.

Thanks.

Re: U-Boot for Nokia RX-51 with BootMenu
 

All I had to pass in was the normal root=/dev/mmcblk0pX argument to tell it which partition to boot to.

Re: U-Boot for Nokia RX-51 with BootMenu
 

Here are all supported variables for bootmenu entry:

ITEM_NAME=""
ITEM_DEVICE=""
ITEM_FSTYPE=""
ITEM_KERNEL=""
ITEM_INITRD=""
ITEM_SCRIPT=""
ITEM_CMDLINE=""
ITEM_USEATAG=""

Try to play with it, maybe you can get nemo booting. Now I do not have time to playing with it.

I tried this (stored kernel uImage-nemo in MyDocs) but not worked:
ITEM_NAME="Nemo"
ITEM_KERNEL="uImage-nemo"
ITEM_DEVICE="${INT_CARD}p1"
ITEM_FSTYPE="fat"

Re: U-Boot for Nokia RX-51 with BootMenu
 

I think you need to add:
ITEM_CMDLINE="root=${EXT_CARD}p6"

or wherever the Nemo partition is.

Re: U-Boot for Nokia RX-51 with BootMenu
 

How did you build the Nemo uImage to add to the boot entry?
Is it the same procedure used for a merged image (uboot + p49) and setting that one instead?

I would guess this will allow more than one O/S can be loaded from several partitions on the sdcard?

Re: U-Boot for Nokia RX-51 with BootMenu
 

!! ${EXT_CARD} is variable ONLY for ITEM_DEVICE !!

in ITEM_CMDLINE you should use root=/dev/mmcblk...

Re: U-Boot for Nokia RX-51 with BootMenu
 

store kernel image (must be in uImage format) to internal/external mmc and set correct variables.

script u-boot-update-bootmenu will then create correct bootmenu configuration

Re: U-Boot for Nokia RX-51 with BootMenu
 

The nemo mobile project releases ready made raw images that you write to an sd card. I should be configured as follows:
partition 1: root filesystem
partition 2: swap
partition 3: /boot

So something like this:
ITEM_NAME="Nemo"
ITEM_KERNEL="uImage"
ITEM_DEVICE="${EXT_CARD}p3"
ITEM_FSTPE="fat"
ITEM_CMDLINE="root=/dev/mmcblk1p1"

Should work, right? But nope, it loads the right kernel (as does run sdboot in the console), but then it just shuts down.

Any suggestions?

I had same problem when tested.
