Hello,
I am trying to recover a BeagleBoard rev C4. Until yesterday, it
booted fine from nand.
Since yesterday I don't get any activity in minicom any more, not even
"40T".
I don't recall having changed anything.
I have tried all the solutions presented in BeagleBoardRecovery - eLinux.org
with no luck.
1/ MMC recovery
NOTE: Using my existing recovery card did not work.
I formated/reformated it
* using the instruction on page Google Code Archive - Long-term storage for Google Code Project Hosting.
* using the mkcard.sh script found here http://www.angstrom-distribution.org/demo/beagleboard/
I also take care of erasing the first flash sector, to make sure MLO
is in the first flash sector after
formatting.
I used different MLO, including the recovery MLO, with no luck.
The result was always the same: booting with S1/userbutton pressed,
nothing happens on minicom
(it worked previously, so I assume communication parameters are fine)
2/ USB recovery
I followed the instructions presented here:
When using the script recover_beagle.sh found in
http://groups.google.com/group/beagleboard/web/beagle_recover.tar.bz2
I never got further than this:
$ sudo ./recover_beagle.sh /dev/ttyUSB0
[sudo] password for gilles:
NOTE:
When you see the message "Waiting for USB device..", Connect USB
Cable to the board with the switch S1 pressed
Keep S1 pressed for 1 second at least after connecting usb cable.
Waiting for USB device vendorID=0x451and productID=0xD009:
No USB device is detected!
3/ UART recovery
I also tried the pserial program from the above archive like this:
$ sudo ./pserial -p /dev/ttyUSB0 -f ../u-boot.bin
lsof: WARNING: can't stat() fuse.gvfs-fuse-daemon file system /home/
gilles/.gvfs
Output information may be incomplete.</blockquote>
Waiting For Device ASIC ID: Press Ctrl+C to stop
Did not read asic ID ret = 1
I did not find anybody on this list which could not even manage to get
USB recovery working. Did I miss something or is this BeagleBoard
broken?
Thank you for any hint!
