To update on my progress of the work on 2 January. I made a mistake in the copying address as you can read in my previous post. I did it again and now the unit starts. But it seems that I damaged my ART file in the process because I get an error message during boot.
ath: phy0: Unable to initialize hardware; initialization status: -5
ath9k ar933x_wmac: failed to initialize device
ath9k: probe of ar933x_wmac failed with error -5
So now I need an ART file to repair the unit. Can anyone send me a copy of his ART file? In the post http://wiki.openwrt.org/doc/howto/restore_art_partition they give instructions how you can make a dump of the art file.
I hope someone can help me.
I have sucessfully restored an Airmusic device with the help of the pyhon script you have also used (but with the right parameters):
sudo python ubootwrite.py --verbose --serial=/dev/ttyUSB0 --write=./image.bin --addr=0x81000000
sudo screen /dev/ttyUSB0 115200
erase 0x9f020000 +0x7C0000
cp.b 0x81000000 0x9f020000 0x7C0000
You can try to restore your ART Partition with the image I have copied from the /dev/mtd4 of my device: 0x0000007f0000-0x000000800000 : "art"
