Re: u-boot for the RX-51 (N900)
 

No, I will not rebase all patches on top of old u-boot tree. If somebody want can do it (all patches and branches are on gitorious). I'm prepairing rx-51 patches for merging into upstream.

Matan branch has only few commits ahead of stskeep. So you can use git bisect to find commit which break your device. Please let me know where is problem. I'd like to see that commit and fix it.

Thanks will do after weekends will look into git bisect first as I have no idea what it is yet :p

Re: u-boot for the RX-51 (N900)
 

I have found out a very very strange problem.

When I use Pali's u-boot image (with power kernel v48) I have a very high power consumption on stand-by/idle
A full charged battery discharge to empty in only 12-13 hours instead of many days.

I have done some tests and I can confirm that on my phone (rev 2101):
- With PR1.3 kernel (no u-boot) = normal power consumption
- With Power kernel v48 with Matan's U-Boot = normal power consumption
- With Power kernel v48 with Pali's U-Boot (prebuild image supplied by Pali) = very high power consumption

Unfortunately I don't understand why

Re: u-boot for the RX-51 (N900)
 

I have same problem with battery. It happends if I boot my builded u-boot binary. kernel-power wihout u-boot is ok. So this must be problem in u-boot.... But now I do not know where...

Re: u-boot for the RX-51 (N900)
 

i noticed the powerconsumption too.
maybe it has to do with twl4030 settings or with the C4-C0 state checkings.
I ran powertop and noticed hign persentage of Cx compare to others...

Re: u-boot for the RX-51 (N900)
 

I'm about to give up.
u-boot can't seem to find the internal emmc and 'external' sdcard cards anymore.
'mmc init 0' should give the external sdcard, 'mmc init 2' should give the internal emmc card. But these command just return 'no MMC card'.

The strange thing is sometimes 'mmc init 1' does work and allows access to the external sdcard.

Just booting noloboot is still no problem and shows both mmc available...

Anybody any hints?

Re: u-boot for the RX-51 (N900)
 

Bad: Now I'm testing all version of u-boot (all branches from gitorious) but no version can access to internal eMMC. I do not know where is problem...

And some good news, I fixed problem with scrolling console.

Re: u-boot for the RX-51 (N900)
 

Pali, I was doing the same. Even took the master from denx.de

Sometimes it does work and I see the emmc (but not the external sdcard).
I think the best change of getting it is start up o in plain maemo and then do a reboot (or power off) from the power-button menu.

I think it is just u-boot not properly initialising the twl403 MMC pins. I'm also looking at the linux kernel sources on how mmc is inititialised (e.g. the nokia patches) and it seems linux is doing a lot more stuff than u-boot does (e.g. initialising clocks).

Re: u-boot for the RX-51 (N900)
 

@pali, did you uplaod the fix for console scrolling somewhere? Thanks!
