Dual boot problem
« on: November 05, 2009, 04:11:17 pm »
I installed the dual boot before.
I had a problem with my Dingux installation, and the launch of Linux was hanging (maybe causing a reboot, I don't remember exactly).

So I formated my SD card, reinstalled the latest toddler pack and now I can't boot at all by pressing select on the "Dinux" screen.
The original firmware boots fine.

I wanted to flash the latest dual boot from october, so I followed the instructions (reinstalled the driver, booted successfully my dingoo as a usb tool, I run these commands:
Code: [Select]
C:\dualdingux>usbtool-win 1 hwinit.bin 0x80000000
USBtool v0.4 - (C) 2008 Maurus Cuelenaere

C:\dualdingux>

So everything seems fine but my Dingoo's screen stays black...

When I reboot, it's the same as before: the original firmware boots, Dingux won't.
My SD card works from the original firmware.

Anybody can help ?

edit: sorry I just realized that this should be in the help section. Unfortunately I can't move it myself. Could a moderator do it for me ?

Had similar problems everytime I wanted to use a new kernel or rootfs. The trick which did it for me was installing from scratch in a certain order:

1. Format SD card
2. Copy zImage to it
3. Copy rootfs to it
4. Copy the local folder to it

That worked fine, no more freezing Dingux screen.

Just read my FAQ, seems to me the dualboot/Dinux got installed properly, but you're having issues with the SD card, quite possibly a weird incompatible FAT32 partition.

The FAQ / Troubleshooting guide should help you on your way.
Write/save problems? Segmentation faults? Black screens? Read the Troubleshooting and FAQ guide first to fix your issues! :)
SD Card readonly/corruption issues? Chkdisk /F and steer clear from DMenu: use GMenu instead!

Thanks, I will try that tomorrow.

Actually the other problem I have is that I can't flash the bootloader again. As there is a new version, I assumed it would be good to flash it as well. And on the french forum I'm part of http://www.playeradvance.org/forum/showthread.php?t=34277 , I'm not the only one having an issue with the bootloader flashing.

Silly quesiton, but you did rename the zImage to match your LCD. Right?

What happens exactly when you hit select on boot?

That did fix my problem with Dingux ! Thanks  ;)

As for the dual boot flashing, I don't want to keep on trying to update it as it is working perfectly right now. And as everybody know in computer science, better is the enemy of good.

Thanks to all of you for your help !

Order seems to be extremely important with these things.

I noticed and wrote that in previous threads. I think it has something to do with the clusters or blocks the files are written to.
Seem to be nessasary to have the kernel in the first blocks of the partition.
