eMMC memory not visible
 
Ouch..

My N900 has had a few problems lately, first the USB came off as per..now the eMMC is unreadable.

I have flashed the thing as I have done countless times before and it is not working. I can flash the rootfs but the vanilla image is giving me the ol'

SU_GET_UPDATE etc error code 1

I have r&d mode'd the phone to check fdisk and try to check the /dev/mmcblk0p1 filesystem but it is simply not present. The rootsfs image is booting up and the phone seems to work, just that the extended memory is not available at all. seems like it is not being mounted at boot time.

I dont really know what to do I have checked the dmesg and all I see is an outdated scsi driver message that could have anything to do with this..

Any diagnostic root images or cool ways to mount or check my eMMC memory would be gratefully received.

Open N900s terminal and type ls /dev/mmcblk0*
It should give /dev/mmcblk0, /dev/mmcblk0p1, /dev/mmcblk0p2 and /dev/mmcblk0p3.
If they all are present, type mount /dev/mmcblk0p1 as root. If not, then your N900 is broken AFAIK

Check the device structure with sfdisk please
Code:
sudo gainroot
sfdisk -l
There is also testdisk from the recovery-tools package, which could do some heuristic testing of the partition to find traces of former file systems.

Re: eMMC memory not visible
 
sfdisk -l returns

nothing.....

and there are no partitions starting mmc on /dev

I cannot get at recovery tools because I only have a basic rootfs file system...

I think it is broken...

Re: eMMC memory not visible
 
Maybe
Code:
lshal | grep mmc
lsmod | grep mmc
will give you some output?

stevec 2011-02-04 19:14
Re: eMMC memory not visible
 
lshal |grep mmc

gives a lot of output I cant type it all in and I cant ssh the device...

lsmod gives..

mmc_block 8964 0
omap_hsmmc 12160 0
mmc_core 46996 2 mmc_block,omap_hsmmc

Thanks for the help..

Re: eMMC memory not visible
 
You might redirect the output of the lshal command to a file
Code:
lshal | grep mmc > lshal.txt
No output on the screen given, everything is in the file lshal.txt. You might it attach to the post here via 'Go Advanced'

Re: eMMC memory not visible
 
I cant think of a way to get the text file off off the phone...

I have no usable disk that I can see from my PC and no way to connect to the n900...no sshd, no connections at all basically..

its in a bit of a limbo unfortunately...

#lshal -s |grep mmc

platform_mmci_omap_hs_1

platform_mmci_omap_hs_1_mmc_host

platform_mmci_omap_hs_0

platform_mmci_omap_hs_0_mmc_host

Email, bluetooth not working also?

stevec 2011-02-04 20:02
Re: eMMC memory not visible
 
They might work, I dont think it matters though as the phone has no configuration..so the email configs are not going to be there

it is in its most basic form, just a factory configured rootfs.

lshal returned 98 configured devices, if that helps at all. I wish I could think of something, i must admit I didnt think about the HAL db at all..

I even loaded the backupMenu V2 rootfs bin that has an ssh daemon built in but I couldnt get putty to connect to it..I guess it is on the USB interface but I dont know which interface that is on my win7 machine and putty does not bind to it properly automatically. My linux is a VM ware image so I dont know about connections with that.If you can give me any clues to get connected through the USB from putty then I might be able to do something with a reflash of rootfs

Is there a way to configure Vmware to be on the same net as your router, if any, and your N900 are?? Virtualbox knowledge only and virtual no knowledge about Windows and Putty, sorry.
Is the USB working at all? Do you have another micro memory card for the external slot?

Compared to the output of my device, the card seems not visible to hal also just the host adapter/port. Also i get 106 devices from lshal

Re: eMMC memory not visible
 
yes, that fits with my theory, that the mmc is not available.

I am jujst watching dortmund vs shalke...sorry for my late replies

:-)

Lucky you! Is Schalke already 04 down like the last time, when this legendary Schalke 05 came alive and true:D:D
Well i dont like Dortmund either, but my Clubs all play against relegation!

Re: eMMC memory not visible
 
hardly lucky a 0-0 game is boring for everyone....

but its my fault..I should have better things to do!!

anyway. I guess its back to the drawing board with this thing. I am playing with android dev to get an openvpn tunnel and SIP g.729 going as thats what I really loved about this box...

mind you the native sendmail and lightttp web server were kind of fun too...I cant see that working on android for a while..

if I cant get it fixed I might have to buy another...but these hardware issues are worrying..

will the N9 be any better?
