If you passed on a NFS directory as rootfs, then removing the mount /tmp/userdata should be enough.

If you passed on a NFS directory as rootfs, then removing the mount /tmp/userdata should be enough.

But leaving the mkdir -p /tmp/userdata/xios/root and the mount -o bind /tmp/userdata/xios/root /root ?

---

Well ignoring the SD card root and trying to get /tmp/userdata to happen on my NFS rather than NAND I hit the following :

Code:

chown: unknown user/group default:default
/etc/init.d/rcS: line 27: /etc/init.d/S10setup: Permission denied
/etc/init.d/rcS: line 27: /etc/init.d/S10setup~: Permission denied
Populating  using udev: udevd[76]: error: runtime directory '/run/udev' not writable, for now falling back to '/dev/.udev'

done

Does this suggest a r/w permissions issue with my NFS rootfs?

*EDIT Red Herring This appears to have been caused by my dropbear folder in my NFS server being ro *

[noggin]

Right.

Having another think about this. Realised I hadn't really looked in etc/fstab - doh!

That's where the other YAFFS2 bit happens - when /recovery is mounted to /dev/mtdblock3 (which I'm not interested in and have commented out?)

Also

Code:

/dev/root   /   ext2 ro,noauto

- how does that interact with my NFS rootfs? Should I replace this line with something like

Code:

192.168.1.16:/home/stephen/SteveDev/target / nfs ro,rsize=8192,hard,intr,nfsvers=3  0 0

?

Should it be read only? Where is the ext2 filesystem situated? Or does my NFS rootfs from the kernel command line over-ride this? As you can tell I'm new to this...

[noggin]

OK - so think I've managed to get a bit further :

Commented out the yaffs2 recovery stuff in fstab. (Not sure I needed to but not sure it's a problem to?)
Commented out the yaffs2 mount and mount bind for /tmp/userdata/pivos/root in S10setup.

Now when I go to /tmp/userdata I don't get garbage.

xbmc still gives me the same error about glxinfo.

I notice that at the end of S10setup everything/something is remounted as read-only ? Does this mean I don't have any r/w filesystems other than tempfs stuff? (Is the standard set-up that the rootfs lives in one bit of NAND flash (system?) and is ro, and userdata lives in another bit of the NAND flash system (user data) and is rw? As I don't have these - do I need to make things rw?


Also I note that top of rcS includes

Code:

export HOME=/root

but that this isn't set when I get to a busybox prompt...

My environment when I get to a # prompt is :

Code:

export HOME='/'
export PATH='/sbin:/usr/sbin:/bin:/usr/bin'
export PWD='/'
export SHELL='/bin/sh'
export TERM='vt102'
export USER='root'
export a9_clk='600M'
export clk81='187500000'
export logo='osd1'
export resolution_size='1280,720'

So I type export HOME=/root manually...

My mounts are :

Code:

rootfs on / type rootfs (rw)
/dev/root on / type nfs (rw,relatime,vers=3,rsize=4096,wsize=4096,namlen=255,hard,nolock,proto=udp,port=65535,timeo=11,retrans=3,sec=sys,mountport=65535,mountproto=,addr=192.168.1.16)

tmpfs on /media type tmpfs (rw,noatime)
tmpfs on /root type tmpfs (rw,noatime)
fusectl on /sys/fs/fuse/connections type fusectl (rw,relatime)

(Should all these be tmpfs?)

Could

Code:

be significant? (I didn't comment out the echo in S10setup about /mounting tmp/userdata)

[noggin]

Been continuing to play.

I commented out the tmpfs line /etc/fstab and this appears to have caused /tmp/ stuff to appear in my /tmp folder on my NFS share. Not sure if this is a good thing or not?

However nothing in /root or /tmp/userdata/xios/root in my NFS share, when I run xbmc I get the glxinfo error, and I can't find an xbmc.log - there's no $HOME/.xbmc folder...

Something wrong with my /root home folder?

As I'm not using any NAND flash yaffs2 stuff - Davilla/j1nx - can you suggest how best to set up so everything is on my NFS ? Think there may be some ro vs rw issues?

(Here's my gdb xbmc UART log : http://pastebin.com/W4Zk6VX8 )

[noggin]

And more playing - though as you can tell I'm not quite sure what I'm doing (apologies for the clogged thread)

Have tried replacing the yaffs2 /tmp/userdata mount with an ext2 SDCard - still booting with my target rootfs on NFS. This seems to work - I have a xios folder on my sdcard now with a root folder in it. (So this suggests that /tmp/userdata is correctly mounting to my SD card and writing to it is happening - as the xios and xios/root directories are being created?)

I've edited S10setup to be :

Code:

mkdir -p /tmp/userdata
mount -t ext2 /dev/cardblksd1 /tmp/userdata
mkdir -p /tmp/userdata/xios/root
mount -o bind /tmp/userdata/xios/root /root

This returns the following :

Code:

Does the chown: unknown user/group default:default mean anything? Looks to be triggered by

Code:

chown default.default /tmp/avahi-autoipd

in S05avahi-setup?

As usual I get A9 logo on uBoot, and this flashes around a bit until the S10setup runs and I get a blank screen (I assume the fb0/1 writes are clearing the framebuffers?)

However I still have to manually type EXPORT HOME=/root (shouldn't rcS do this during init.d?) and xbmc still fails with glxinfo errors. (If I try running it automatically with S95xbmc in init.d I get the assertion error)

I can't find an xbmc.log anywhere. (Could it be trying to write to a read only fs?)

Still something wrong with "/root"?

Another thought - this is nothing to do with UART vs SSH access is it? I'm using UART.

[noggin]

Tried another route to getting HOME=/root at bootup. Edited /etc/profile to add export HOME=/root (Is this a bad thing?)

When I SSHed in I saw that HOME=/root when I did an env. I then tried to run xbmc via SSH. No dice. Same glxinfo fail.

However this time I managed to find /root/.xbmc/temp/xbmc.log

Here's the log : http://pastebin.com/9fzhjyvQ

However I think they must still be mounted on tmpfs not my SDCARD - as I don't see anything on my SD CrARD when I try and mount it on another laptop. I also got lots of ext2fs INODE issues... Might try reverting to NFS again for /root...

As ever - if I haven't bored everyone to death with this - advice appreciated.

Thanks Davilla.

Yep. I've changed S10setup now to mount -o remount,rw / (and I chmod -R 777 all of /root in case...) (I discovered that a big issue as to why I was getting confused was that gedit was saving backups as S10setup~ which were also running in init.d - and I hadn't got View Hidden Files enabled...)

Now get : http://pastebin.com/ktZSrPyi which seems to have got rid of the errors above? It's useful having /root in my NFS - I can now easily access the xbmc.log from my main PC.

There's a difference between SSHing in and UARTing in I've discovered. UARTing in doesn't give me HOME=/root, but SSHing in does. (I added HOME=/root to /etc/profile in case that's relevant)

I'm now doing everything via SSH.

Here is what happens when I try to run xbmc within gdb (my HDMI connected TV flashes its on-screen display indicating a video signal change) :

Very true!

Well I did what davilla suggested - and the results are strange.

I get nothing when I type cat /sys/class/amhdmitx/amhdmitx0/disp_cap and just a blank line when I type cat /sys/class/display/mode either straight after logging in as root via SSH or after running xbmc. If I type cat /sys/class/hdmitx/amhdmitx0/disp_mode I get VIC:0.

Does this suggest that there's something borked in my HDMI drivers? Should I get disp_cap and display/mode information on power up?

If I run gdb on xbmc.bin and then run --standalone I DO get responses after quitting.
cat /sys/class/display/mode

Code:

720p50hz

cat /sys/class/amhdmitx/amhdmitx0/disp_cap

Code:

null edid

cat /sys/class./amhdmitx/amhdmitx0/edid

native Mode 0, VIC (native 0):

Audio {format, channel, freq, cce}
Speaker Allocation: 0
Vendor: 0

Which is null?

cat /sys/class/amhdmitx/amhdmitx0/disp_mode

Code:

VIC:19

(Which I believe is 720p50?)

What does running in gdb do that makes these more sensible?

Backtrace stopped: previous frame identical to this frame (corrupt stack?)

This was with the box connected directly via HDMI into my Sony Full HD tv. (Which accepts 1080i at 50/60Hz, 1080p at 24/50/60Hz and 720p at 50/60Hz - plus all the 1000/1001 variants, and the 480i/p and 576i/p SD stuff)

Something wrong with EDID reading, HDMI set-up?

This is what I have in /sys/class :

For info - I booted into Android on the same box and got this (this time connected to a Samsung 1680x1050 LCD I used in case the Sony was not playing EDID-ball) :

Code:

root@android:/sys/class/amhdmitx/amhdmitx0 # cat edid                          
EDID block number: 0x1
Source Physical Address[a.b.c.d]: 1.0.0.0
native Mode f1, VIC (native 19):
ColorDeepSupport 80, MaxTMDSClock 140
19 4 5 20 3 18 16 31 32 33 34
Audio {format, channel, freq, cce}
{1, 1, 7, 7}
Speaker Allocation: 1
Vendor: c03

and this

Code:

1|root@android:/sys/class/amhdmitx/amhdmitx0 # cat disp_cap

720p
1080i
1080p
720p50hz*
1080i50hz
1080p50hz

Which is much more what I'd expect.
