I've also got the V2 release working without any major problems (a fantastic achievement, thanks Jonathan et al). I have a few observations and questions that may help others.

I did stop the NAND backup process because it was incredibly slow. "top" showed that the system wasn't using much CPU but the load was over 2.0 Using "df" also revealed that the USB stick was only having 16 bytes written to it every second or so.

The E3 keyboard is mapped as a standard desktop keyboard so most shifted characters are wrong and symbol-shift characters are ignored.

There was a new keymap posted to the list by David Given a while back, though I had meant to update the one in the driver itself.

I replaced the supplied 2.6.16 uImage with the one from the 2.6.17 directory in the hope that the keyboard mappings would be fixed. It worked but it only provided a shell login for the serial connection unlike the 2.6.16 image which provides both a serial and an onboard E3 login.

2.6.16 is the one that supports most things; later kernels gradually get more of the devices supported by mainline linux-omap rather than having to be patched, but both the keyboard and sound drivers weren't written by me so they tend to end up last on my list of things to forward port. I'm hoping to find some time to get a 2.6.18 kernel up and running in the next week or two, along with the diminishing patch set.

The copying of the Linux image from NAND seems slow, I recall some discussion about this being fixed within u-boot. Does the copy of u-boot in the V2 release contain this fix?

No, the version in V2 is 1.4, but there's a patch against uboot git that adds support but also speeds up the Linux image loading.

Umm... Where would that patch be ? :)

I hope it's not u-boot-amsdelta-20060519.diff, because it made no difference for me :(

I thought I'd give the release a try (up to now I've always copied the kernel over serial and used nfs root) but it appears that I have some bad blocks in the NAND on my device:

Found ldr.img Erasing /dev/mtd3 Erasing 16 Kibyte @ 0 -- 0 % complete. Skipping bad block at 0x00004000

Skipping bad block at 0x00008000 Erasing 16 Kibyte @ c000 -- 18 % complete.Erasing 16 Kibyte @ 10000 -- 25 % complete.Erasing 16 Kibyte @ 14000 -- 31 % complete.Erasing 16 Kibyte @ 18000 -- 37 % complete.Erasing 16 Kibyte @ 1c000 -- 43 % complete.Erasing 16 Kibyte @ 20000 -- 50 % complete.Erasing 16 Kibyte @ 24000 -- 56 % complete.Erasing 16 Kibyte @ 28000 -- 62 % complete.Erasing 16 Kibyte @ 2c000 -- 68 % complete.Erasing 16 Kibyte @ 30000 -- 75 % complete.Erasing 16 Kibyte @ 34000 -- 81 % complete.Erasing 16 Kibyte @ 38000 -- 87 % complete.Erasing 16 Kibyte @ 3c000 -- 93 % complete. Writing ldr.img to /dev/mtd3 end_request: I/O error, dev mtdblock3, sector 32 dd: /dev/mtdblock3: Input/output error

Is it possible to move ldr further down in /dev/mtd3 ? I tried this using

dd if=/media/sda1/ldr.img of=/dev/mtdblock3 bs=16384 seek=3

that seemed to write OK, but the e3 wont boot of the nand yet. I get an error about missing kernel params, which repeats continuously.

Anyone got any ideas?

Matt
