Re: [ts-7000] ts-7800 boot from SD card

[Alexey Vdovin <>]

Dave,

By my understanding SD card partitions are:
1 - vfat - Win SDK
2 - RAW - zImage
3 - ext2 - initrd
4 - ext3 - linux

That is for factory SD card.

Could you confirm, you made partition 3 as ext3?

I have a ts-7800 that boots from an SD card. I made a copy of that
card, using dd for partitions 1 and 2. I made partition 3 an ext3,
and partition 4 a jfs, per the original SD card. Then I used cp -au
<src card> <target card> for partitions 3 and then 4.

The card I made will only work if I remove the jumper that tells the
ts7800 to boot from the card. Without the jumper, the unit boots from
nand and then the SD card. While I can use it that way, I'm trying to
understand what the difference might be, because I must be doing
something wrong.

BTW, I can't use dd on partition 4, because the target card is smaller
than the source card, although both are 2 GB. I've tried on 4
different SD targets. All the cards are SanDisk.

I asked Derek at Technologic why it can boot through nand first and
then the card, but not the card directly. He hasn't answered me so I
hope someone here can offer some clues.

Thanks.
