How to burn image to T-Flash on Linux.

[Jourge Sena]

Checked with Odroid image Release-2010_03_22.

Connect the T-Flash reader to your Linux PC.

Check the T-Flash's device name.
$ su
# ls -l /dev/disk/by-id
--------
lrwxrwxrwx 1 root root 9 2010-03-22 23:23
usb-SD_Card_Reader_and_so_on -> ../../sdx
--------
In this case, the T-Flash's device name is /dev/sdx

Check the T-Flash's total sector number.
# fdisk -l -u /dev/sdx
--------
Disk /dev/sdx: 1977 MB, 1977614336 bytes
61 heads, 62 sectors/track, 1021 cylinders, total 3862528 sectors
--------
In this case, the T-Flash's total sector number is 3862528

Calculate offset.
TFLASH_SECTORS = (T-Flash's total sector number)
OFFSET_BL1 = TFLASH_SECTORS - 18
OFFSET_BL2 = TFLASH_SECTORS - 1074
OFFSET_KERNEL = TFLASH_SECTORS - 9266

Now burn it.
# dd bs=512 seek=OFFSET_BL1 count=16 if=u-boot.bin of=/dev/sdx
# dd bs=512 seek=OFFSET_BL2 if=u-boot.bin of=/dev/sdx
# dd bs=512 seek=OFFSET_KERNEL if=zImage of=/dev/sdx
# dd bs=512 if=Odroid-eclair-2.1.r2-100322.img of=/dev/sdx

(in this case)
TFLASH_SECTORS = 3862528
OFFSET_BL1 = TFLASH_SECTORS - 18 = 3862510
OFFSET_BL2 = TFLASH_SECTORS - 1074 = 3861454
OFFSET_KERNEL = TFLASH_SECTORS - 9266 = 3853262
# dd bs=512 seek=3862510 count=16 if=u-boot.bin of=/dev/sdx
# dd bs=512 seek=3861454 if=u-boot.bin of=/dev/sdx
# dd bs=512 seek=3853262 if=zImage of=/dev/sdx
# dd bs=512 if=Odroid-eclair-2.1.r2-100322.img of=/dev/sdx

1/ Can somebody put the content of this thread on the wiki, I am not
sure on which page it should go.
2/ I created a script with previous content

-------------
#!/bin/bash
# Customise this line
TFLASH="/dev/sdd"

#
TFLASH_SECTORS=`fdisk -l -u $TFLASH | grep sectors | head -n 1 | cut -
d',' -f4 | cut -d' ' -f3`

# Do calculation
OFFSET_BL1=$(($TFLASH_SECTORS-18))
OFFSET_BL2=$(($TFLASH_SECTORS-1074))
OFFSET_KERNEL=$(($TFLASH_SECTORS-9266))

# Ask for correct calculation
echo -n "NSectors: $TFLASH_SECTORS, Do you want to continue: "
read ANS

#Do job
if [ "$ANS" == "yes" ]; then
dd bs=512 seek=$OFFSET_BL1 count=16 if=u-boot.bin of=$TFLASH
dd bs=512 seek=$OFFSET_BL2 if=u-boot.bin of=$TFLASH
dd bs=512 seek=$OFFSET_KERNEL if=zImage of=$TFLASH
dd bs=512 if=Odroid-eclair-2.1.r2-100322.img of=$TFLASH

Cool! Thanks!
I modified it a bit for convenience.

tfburner.sh
-------------
#!/bin/bash
LC_ALL="C"
TFLASH=$1
ROOTFS=$2
# Check args
if [ -z "$TFLASH" ] || [ -z "$ROOTFS" ]; then
echo "Usage: $0 T-Flash-device Odroid-img"
exit 1
fi
# Check TFlash Sectors

TFLASH_SECTORS=`fdisk -l -u $TFLASH | grep sectors | head -n 1 \

| cut -d',' -f4 | cut -d' ' -f3`

# Do calculation
OFFSET_BL1=$(($TFLASH_SECTORS-18))
OFFSET_BL2=$(($TFLASH_SECTORS-1074))
OFFSET_KERNEL=$(($TFLASH_SECTORS-9266))
# Ask for correct calculation

echo "T-Flash-device:$TFLASH Odroid-image:$ROOTFS"
echo -n "NSectors:$TFLASH_SECTORS, Do you want to continue(yes/no): "

read ANS
#Do job
if [ "$ANS" == "yes" ]; then
dd bs=512 seek=$OFFSET_BL1 count=16 if=u-boot.bin of=$TFLASH
dd bs=512 seek=$OFFSET_BL2 if=u-boot.bin of=$TFLASH
dd bs=512 seek=$OFFSET_KERNEL if=zImage of=$TFLASH
