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

I have Nemo (fresh install) on eMMC so no problem for SD Class 10 or similar.
I have tried to boot Nemo with u-boot and as I have told some weeks ago, but it has always failed to boot (many I/O errors -110)

Today I have tried three times with flasher and the results has been always the same: No boot and many I/O errors

In the past I have loaded many times MeeGo / Nemo kernel with flasher and it has always worked!
So it is impossible that now it no longer works.

I have done an experiment:

1. Flashed a Power Kernel v49 without u-boot (before I had PK49 with latest Pali's u-boot)
2. Booted Maemo one or two times (I don't remember) and then powered off.
3. Loaded Nemo's Kernel with flasher

This time Nemo has booted correctly without errors!!

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

Is it possible to listen for errors through USB cable (instead of serial?)? Such option is mentioned on http://wiki.openmoko.org/wiki/U-boot...tty_from_Linux but is it possible with N900 and specifically with this new U-Boot?

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

I am not 100% sure but it seems that latest Pali's u-boot have little power consumption issue yet.

Since I have removed u-boot (to test latest Nemo) I have noticed a much longer stand-by.

Now I am about 60 hours after last full battery recharge and I still have about 44% of battery (of course with very little usage of N900), before with pali's u-boot I have difficulties to reach 48 hours (with same usage).

BatteryGraph's graph shows that before idle power consumption was about 10% of battery on 5 hours, now instead it is about 10% of battery on 18 hours.

It seems that with pali's u-boot installed idle power consumption is 3-3.5x greater

I repeat it is not a scientific test, I should have to do many tests with and without pali's u-boot to confirm or not the situation.
But unfortunately now I have no time to dedicate to testing, if someone other can verify and report the results

According to https://gitorious.org/u-boot-shr/u-b...ccd096a7/diffs
USB tty support was dropped.
Is it possible to re-enable it without recompiling U-Boot?

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

well at the moment am trying to get nitdroid to boot from an EMMC partition, the only problem am having is when setting enviroment I have to choose were to load the uImage from and am presented with mmc 1:1 which is the sd card, but is the maemo partition mmc 0:5? Since its the 5th partition, or even mmc 0:4?

edit, am not 100% sure how to merge the boot.scr i generate with the bootmenu.scr

also ive had a lot of stability issues with kernel 49, yes i have overclocked, but that has never been an issue before, the phone never randomly rebooted till i installed uboot

right it seems to reboot when i use the network at certain times, wireless network, mainly when i connect to FaceBook am not sure why yet but am looking into it.

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

when i did your command on http://www.smartphonetab.net/forum/s...-MeeGo-su-eMMC

i partitoned emmc with ext4 and i can not mount it
mount-t ext4-o noatime / dev/mmcblk0p4 dst-part /

is that command correct ??

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

You got the spaces all wrong. Try:

# mount -t ext4 -o noatime /dev/mmcblk0p4 /dst-part

make sure /dst-part exists, obviously.

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

Not "/dst-part" but "dst-part".
So: mount -t ext4 -o noatime /dev/mmcblk0p4 dst-part

With "/dst-part" you search on root dir and theorically dst-part is on /home/user, so wrong path
