dfu-util shows only one partition

Description

This bug could be related only to my OM. Every time I run dfu-util (ubuntu 10.04, ubuntu 10.04 x64, windows xp with dfu-util for windows) in NOR boot menu I can see only one partition:

Found Runtime: [0x1d50:0x5119] devnum=1, cfg=0, intf=2, alt=0, name="USB Device Firmware Upgrade"

Which is not named rootfs but acts like rootfs. I guess my OM doesn't switch to DFU mode during dfu-util -l (it should, right?), and stays in runtime mode (?)

After flashing rootfs (OM shows DFU mode, configured device 1 etc..) dfu-util shows this partition as :

Found Runtime: [0x1d50:0x5119] devnum=2, cfg=0, intf=0, alt=0, name="rootfs"

This time seems ok (notice intf changed to 0), but still - where are my kernel / u-boot partitions ? Can't flash them if dfu-util doesn't recognise them.

my printenv + lsmod + lsusb + dmesg : ​http://pastebin.pl/26214 (should I attach here?)

MY other thoughts: Could it be host kernel related or latest uhci_usb ? I will try to confirm this bug on other distros cuz hard to say now is it host related or my OM related.

PS. I've flashed Qi bootloader some time ago (~1 year) and shr-u rootfs recently. But didn't checked what partitions were available just before flashing rootfs.

Also tested dfu-util 0.0+r4880-1 (ubuntu repo).. same issue..

comment:2 Changed 3 years ago by lindi

Thank you for reporting a bug. Please capture the usb traffic using wireshark to a pcap file and attach it here.

Also, if you can boot your phone. Please the following commands and add their output to the bug report:

strings /dev/mtdblock0 | grep U-Boot | head -n1
strings /dev/mtdblock1 | grep U-Boot | head -n1

comment:3 Changed 3 years ago by lindi

Sorry, wiki markup in a bug tracking system confused me again, the commands were

strings /dev/mtdblock0 | grep ^U-Boot | head -n1
strings /dev/mtdblock1 | grep ^U-Boot | head -n1

I just encountered the same problem. I haven't figured out how to add comment in trac yet, and I have not been able to get Wireshark to logging either.

My findings so far:
# dfu-util -l
dfu-util - (C) 2007-2008 by OpenMoko? Inc.
This program is Free Software and has ABSOLUTELY NO WARRANTY
Found DFU: [0x1d50:0x5119] devnum=10, cfg=0, intf=0, alt=6, name="rootfs"

On some points different from your example, the symptoms are similar.

Maybe related:

  • booting from uboot does not work anymore since opkg-update about a month back
  • booting via Qi and then the top-button gives me a working environment BUT only since I reflashed the rootfs tonight; for about a month, the screen would not wake up after booting.

Once I find some time I'll run the proposed test on the phone and try some more with Wireshark: there did not seem to be related traffic on any of the USB-interfaces when running dfu-util to flash the kernel or backup the rootfs (while in uboot, so the IP was not available for backup..)

ok, as it seems, I recently _have_ found how to add comments to Trac (overlooked the comment box, or did not refresh the cache after registering), but I haven't found the edit post button yet ;-)

usb wireshark capture

comment:6 Changed 3 years ago by gravis

ok. I've added usb capture during running dfu-util -l

I've realised that frame length of 4th packet is 64bytes (according to header) but seems it was transmitted bigger? See that device name string is longer than captured one..

Would you like me to upload a capture from full connection (from turning device on, then dfu-util -l, then waiting for uboot timeout) ? Or is it enough?

I'll upload those mtdblock strings in a minute..

comment:7 Changed 3 years ago by gravis

OK

check my greps here (second one gave me nothing so I've grepped with more greedy rule)

Thank you for all the information you provided. I can reproduce your problem with dfu-util 0.0+r4880-1 from debian unstable and dfu-util 0.0+r4067-3.1 from debian stable. Both were run under linux 2.6.32-amd64-lindi2.

The output was

gravis, what kernel do you have on host?

comment:12 Changed 3 years ago by gravis

I've checked same machine with previous kernel : 2.6.31-15 same issue..
but it's mainly the same kernel.

comment:13 Changed 3 years ago by lindi

This also happens with 2.6.26-2-486 kernel of debian stable. I am bit puzzled. How did this ever work?

When I was updating that Qi bootloader ~1 year ago I remember I saw all the partitions. Since then I didn't touched uboot / kernel partitions at all. Just rootfs recently.

Which distro/kernel is confirmed working with dfu-util (showing all partitions)? Wandering where to chroot..

With the kernel 2.6.32-24 it started to working.. but differently?

Ok I know how all those things work now.

Found Runtime: [0x1d50:0x5119] devnum=1, cfg=0, intf=2, alt=0, name="USB Device Firmware Upgrade"

See that intf=2 and cfg=0 ? Now compare this to my lsusb output.

This means that output was taken from first configuration (bConfigurationValue 1), third interface (bInterfaceNumber 2), interface is named "USB Device Firmware Upgrade"

But in fact, when OM is flashed it shows

Found Runtime: [0x1d50:0x5119] devnum=2, cfg=0, intf=0, alt=0, name="rootfs"

Which is first configuration (bConfigurationValue 1), first interface (bInterfaceNumber 0), which is AT-commands (v.25ter) Control Interface.

So different protocol is used to list partitions (UDF), and different one to flash them (AT terminal upload (?)).

Once we force dfu-util to use interface 0 it will show all the partitions (coming from AT query, rather than innacurate DFU).

so 

dfu-util --intf 0 -l

should shows correct partitions and all flashing commands should have --intf 0 option.

the problem is dfu-util ignores --intf 0 during listing..

but during flashing it works like a charm!

Conclusion:

always use --intf 0 when flashing with dfu-util.

[solved]

.. am I right with all those thoughts ?
