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!!

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?

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 works but is disabled because it prevents the current Maemo kernel from booting.
USB tty support was dropped.
Is it possible to re-enable it without recompiling U-Boot?

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.

You got the spaces all wrong. Try:

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

make sure /dst-part exists, obviously.

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
