Dd Image Of A Working Sd Card For Firm Update

[Tetedeiench]

Heya guys,

I just got my hands on a working SD ( SanDisk 256MB), and i could easily update my kernel AND uboot.

So i figured i could just make an image of it using DD under linux, and give it to you... give it a shot on your cards !

here's the link :

I included all the files from the 3rd firmware BUT the gp2xboot.img file. Just to be safe !

Needed : a SD-card of AT LEAST 256MB. 512 and 1Gb are fine. You'll only see 256MB on it after installing, but you can make it back to it's original size afterwards

How to install : unrar the firmware, then type down this command :
dd if=sd.dd of=/dev/sdX

where X is the letter assigned to your SDCard ( for me, it was sdc). Then, take out your card, plug in your gp2x, and see if it works !

I made an image of the whole card, not of the partition !

Tell me if it works. if it doesn't.... well, the partition table isn't at fault on your card, obviously

Oh, and if it helps, here's how the working card partition table looks like :

Disk /dev/sdc: 252 MB, 252968960 bytes
16 heads, 32 sectors/track, 965 cylinders
Units = cylinders of 512 * 512 = 262144 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sdc1               1         965      246989+   b  W95 FAT32

Disk /dev/sdc: 16 heads, 32 sectors, 965 cylinders

tested and failed

edit: see everything in linux, nothing from GP2X's explorer :huh:

how do you modify the size to the card's size? (i have 512 )

I happen to own the same card, but I don´t understand why have you left that gp2xboot.img file out. Should we copy it into the card after doing the dd?

​

Because that file is notorious for bricking units.

​

if that file fails flashing, your GP2X gets bricked, so it's not very wise to keep this file for experiments

Tried and failed. I've run out of ideas. Thanks anyway.
