Hello, and thank you for your help so far.
I connected my device via USB and read some paramater. Ahh something
strange first: I made an update of U-Boot. I downloaded it from here:
http://downloads.openmoko.org/distro/unstable/daily/om-gta02/20100131/
but the prompt I get is still UBoot 1.3.2-moko12 May 9 2008. I have
allready heared that U-Boot is not so strong supported any longer, but
is this really the newest release?
Anyway: I connected to my device with cu. Then I called a printenv:
GTA02v6 # printenv
boot_menu_timeout=60
bootargs_base=rootfstype=jffs2 root=/dev/mtdblock6
console=ttySAC2,115200 console=tty0 loglevel=4 regular_boot
bootcmd=setenv bootargs ${bootargs_base} ${mtdparts}; nand read.e
0x32000000 kernel 0x200000; bootm 0x32000000
bootdelay=5
menu_1=Boot from microSD (FAT+ext2): setenv bootargs ${bootargs_base}
rootfstype=ext2 root=/dev/mmcblk0p2 rootdelay=5 ${mtdparts} ro; mmcinit;
fatload mmc 1 0x32000000 ${sd_image_name}; bootm 0x32000000
menu_4=Set console to USB: setenv stdin usbtty; setenv stdout usbtty;

partition=nor0,0
mtddevnum=0
mtddevname=nor
Environment size: 1093/262140 bytes
Changed the bootdelay to 10. Saved that change and tried again , but the
problem remains.
I tried to initialize the microSD-card:
GTA02v6 # mmcinit
Card Type: SD 2.0 SDHC
Manufacturer: 0x02, OEM "TM"
Product name: "SA04G", revision 0.4
Serial number: 2620391846
Manufacturing date: 2/2010
MMC/SD size: 3MiB
and tried to read from it:
GTA02v6 # ext2ls mmc 0
Failed to mount ext2 filesystem...
** Bad ext2 partition or disk - mmc 0:1 **
Ahh this is new. I get a new error: 1.8900000] SoftDog: cannot register
miscdev on minor = 130 (err=-16)
I think that my settings are quit normal, the only thing which stands
out is "root=/dev/mtdblock6" instead of mtdblock4. But there is no
information about the meaning:
http://wiki.openmoko.org/wiki/Bootloader_environment.
Anybody who knows where the problem is?
Thanks Christian
