U-boot on DIR-505

[FelixLeo]

Hi pepe2k,
I do have a D-link DIR-505 A1 device
and did hear about your project on another project based on openwrt
and they did create the following package to modify the u-boot on D-link 505 A1
http://ofmodemsandmen.com/download/uboot/dir505a1.zip
I did reach until the point where I did backup my u-boot via their openwrt image,
but got stuck on the point where the new u-boot is created as my original u-boot is only 64kb
and not 128kb, so if I overwrite it with the modified one it will theoretically overwrite all my custom settings if any present in the 64kb chunk.
root@OpenWrt:~# cat /proc/mtd
dev: size erasesize name
mtd0: 00010000 00010000 "u-boot"
mtd1: 00010000 00010000 "art"
mtd2: 00010000 00010000 "mac"
mtd3: 00010000 00010000 "nvram"
mtd4: 00040000 00010000 "language"
mtd5: 00780000 00010000 "firmware"
mtd6: 000f99aa 00010000 "kernel"
mtd7: 00686656 00010000 "rootfs"
mtd8: 00470000 00010000 "rootfs_data"

root@OpenWrt:/tmp# dd if=/dev/mtd0 of=/tmp/u-boot.bin
128+0 records in
128+0 records out

Just for testing purpose I did try to write my original backup to the md0 back to see if this step works

root@OpenWrt:/tmp# mtd write /tmp/u-boot.bin "u-boot"
Could not open mtd device: u-boot
Can't open device for writing!

Would it be possible for you to have a look and tell me what am I doing wrong?

Thanks a lot
