Petr --
Thanks a ton for patching this thing up for me to test. I really appreciate it.
Here's where I am:
1. Booting from standard ts-7400 into NAND flash.
2. Put your uClib tarball on my nfs server
3. using bootload to launch your new kernel
bootload -c "console=ttyAM0,115200 ip=dhcp root=/dev/nfs
nfsroot=192.168.100.7:/home/sethb/ynezz" zImage-2.6.34-r3-ts72xx.bin
The first time it booted ok, but seemed to hang on the startup of the
NTPclient. I just moved the S65ntpclient file out of the way in /etc/rc5.d and
it finished just fine!! (boot spew pasted a little bit below)
A couple of things look funny:
* MTD partitions look like they came from a 7200...standard spew looks like
this:
Searching for NAND flash...
NAND device: Manufacturer ID: 0xec, Chip ID: 0x75 (Samsung NAND 32MiB 3,3V
8-bit)
Scanning device for bad blocks
Hardware ECC detected
Using MBR partition definition
Creating 4 MTD partitions on "NAND 32MiB 3,3V 8-bit":
0x00000000-0x02000000 : "whole chip"
0x00004000-0x00204000 : "kernel"
0x00204000-0x00404000 : "initrd"
0x00404000-0x02000000 : "rootfs"
yaffs: dev is 7939 name is "1f:03"
yaffs: Attempting MTD mount on 31.3, "1f:03"
* serial port ttyTS0 doesn't show up...the standard spew from the 2.4.26-ts11
kernel looks like this:
ttyAM0 at MMIO 0x808c0000 (irq = 52) is a AMBA
ttyAM1 at MMIO 0x808d0000 (irq = 54) is a AMBA
ttyAM2 at MMIO 0x808e0000 (irq = 55) is a AMBA
EP93XX_AMBA detected a TS-7400 with TS-7412 present
TS-UART/7400 detected a TS-7400 with TS-7412 present
ttyTS0 at MMIO 0x12400000 (irq = 33) is a TSUART
Although I tried many times, I could never get PPP to work at all. microcom
would let me issue commands to the modem, but every time I try to "pppd call
att", it goes through the chat script but never gets any response from the
modem.
Also, I'd never heard of open embedded, so thanks for the heads up.
I'm not sure where to go from here (except to bed), but I wanted to let you
know the results of what I'd tested so far.
Thanks again for the help!
