Wow, yes I have. And now, may I try something like:
mount -t auto /dev/tbml8 /what_name?
Code: Select all

You mean to execute something like this?
Code: Select all
# df -h

/dev/tbml6 3.1M 3.1M 0 100% /
none 10.0M 4.0k 10.0M 0% /dtv

# /mtd_exe/rc.local
I think that:
1) test monkey mustn't have the 3000.2 firmware (not me)
2) test monkey must have ex-link cable and functional serial debug console (not me)
3) maybe something is still missing, I remember, that there is some file which is used as firmware switcher or pointer, isn't it?

instead of mounting that partition, dump that flash partition to USB flash disk and examine on PC if it's 3002 or older version.
It it's older, than you could move further and could force TV to use alternative software via /mtd_rwarea/partitionswitch file...

It seems that:
1) exe.img.8 is my previous exe.img version 2004.1, because it is binary different from exe.img.10 and contains string T-CHL7DEUC-2004.1 (exe.img.10 contains string T-CHL7DEUC-3000.2)
2) appdata.img.9 is at least different from appdata.img.11
Code: Select all
# bml.dump /dev/bml0/8 /mtd_swu/exe.img.8
+----------------------------------------------------------------------+
| bml.dump : Low-level Partition Dump Tool for NAND Flash Memory |
+----------------------------------------------------------------------+
This utility program can be used to dump the specified low-level partition. However, the reserved area is not dumped by this utility
This program is operated over FSR based
You will dump partitial partition
100%
All of the flash memory units have been dumped successfully.
# mv /mtd_swu/exe.img.8 /dtv/usb/sda1
# bml.dump /dev/bml0/9 /mtd_swu/appdata.img.9

What to do now? Execute this?
Code: Select all
# /mtd_boot/MicomCtrl 23
# killall -9 exeDSP
# umount /mtd_exe
# umount /mtd_appdata
# mount -t auto /dev/tbml8 /mtd_exe
# mount -t auto /dev/tbml9 /mtd_appdata
# rm /mtd_rwarea/PartitionSwitch_1_0
# touch /mtd_rwarea/PartitionSwitch_0_0
# /mtd_exe/rc.local

Himm, it sounds good to me.
I don't know which is correct
Code: Select all
PartitionSwitch_0_1 or PartitionSwitch_0_0 or PartitionSwitch_1_1
So please try with
Code: Select all
# /mtd_boot/MicomCtrl 23
# killall -9 exeDSP
# umount /mtd_exe
# umount /mtd_appdata
# mount -t auto /dev/tbml8 /mtd_exe
# mount -t auto /dev/tbml9 /mtd_appdata
# /mtd_exe/rc.local
and if it works, than we can make permanent changes via using "PartitionSwitch"

Someone with two switchable firmwares can tell us which combination is correct:
Code: Select all
PartitionSwitch_0_1 or PartitionSwitch_0_0 or PartitionSwitch_1_1
Now I have:
Code: Select all
# ls -al /mtd_rwarea/PartitionSwitch*
-rwxr-xr-x 1 root 0 0 Jan 1 1980 /mtd_rwarea/PartitionSwitch_1_0

Ouch, there are all of these strings in exe.img:
Code: Select all
/mtd_rwarea/PartitionSwitch_0_0
/mtd_rwarea/PartitionSwitch_0_1
/mtd_rwarea/PartitionSwitch_1_0
/mtd_rwarea/PartitionSwitch_1_1
Which one is complementary to my actual PartitionSwitch file?
