Hello!
While trying to edit u-boot environment I experienced this strange
behaviour, which, I think, is rare because nobody reported this yet. My
U-Boot is 1.3.2-moko12 (May 9 2008 - 10:28:48).
Initially I have menu_1 ("Boot from microSD (FAT+ext2)") as follows:
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
Changing it to new one:
setenv menu_1 Boot from microSD (FAT+ext2): setenv bootargs
glamo_mci.sd_max_clk=10000000 \$\{bootargs_base\} rootfstype=ext2
root=/dev/mmcblk0p2 console=ttySAC2,115200 console=tty0 loglevel=4
regular_boot rootdelay=5 \$\{mtdparts\}\; sleep 1\; mmcinit\; sleep 1\;
fatload mmc 1 0x32000000 \$\{sd_image_name\}\; bootm 0x32000000
Note that every special character is escaped. I'm trying to make a
permanent boot menu for microSD invocation.
Now it is (taken copy-paste from minicom console with the help of
printenv):
menu_1=Boot from microSD (FAT+ext2): setenv bootargs
glamo_mci.sd_max_clk=10000000 ${bootargs_base} rootfstype=ext2
root=/dev/mmcblk0p2 console=ttySAC2,115200 console=tty0 loglevel=4
regular_boot rootdelay=5 ${mtdparts}; sleep 1; mmcinit; sleep 1; fatload
mmc 1 0x32000000 ${sd_image_name}; bootm 0x32000000
Seems good. But selecting this menu item "Boot from microSD
(FAT+etx2)" *on the phone* says something like:
Unknown command 'dout' - try 'help'
Obviously it's a part of the word "stdout". How?? Other items
selection and their subsequences:
* "Set console to USB"
Unknown command '_image=uImage.bin' - try 'help'
* "Set console to serial"
Unknown command '1973-nand' - try 'help'
* "Reboot" (two error lines exactly as follows!)
Unknown command '=physman-flash:-(nor)' - try 'help'
(factory),0x0f6a0000(rootfs)' - try 'help'
* "Power off"
Unknown command 'actory),0x0f6a0000(rootfs)' - try 'help'
Only plain "Boot" is working. I can boot from microSD from u-boot
command line managing it from desktop, and NOR menu works on the phone
as well if I didn't do any environment changes.
I see it as environment broken and afraid to say "saveenv" which can
make this uncertain state permanent. What can it be, have anybody seen this?
