Re: qemu emulator for the mini2440

I pushed my latest changes to the git in the -stable branch; check the new mini2440/mini2440_start.sh script; thats also the directory the script will look into to load u-boot, the nand etc..
I added the emulated usb and a usb keyboard, and that seems to work.

Re: qemu emulator for the mini2440

Bah :

+ ethernet doesn't work in the kernel so far (dhcp fails).
+ And maybe the touchscreen has the wrong coordinates
+ and yes the NAND seems borken obviously... since jffs2 doesn't work

But well, there's only me so far ! :D

Re: qemu emulator for the mini2440

I haven't managed to load stuff from the jffs2 either for the monent. It could be for various reasons. The NAND seems happy (despite the eraseblocks) so it could be the first ARM executable (init) fails for some reason... I'm going to try to get the SD working, as it will tell us if it's the nand an...

Re: qemu emulator for the mini2440

Pushed a few more changes to my branch. I reworked the NAND code to try to find why kernel reports bad blocks. Also why I can't seem to boot from NAND direct. Made plenty of cleanups. Seems u-boot loads itself from NAND just fine (I checked) but fails to jump to new code. If I load a 'fake' copy in ...

If you look at the schematic you see the "5V" for the LCD is unregulated, it comes straight from the wall; I don't know how the decoupling is done on the back of the LCD but maybe it would also need a couple of capacitors to work properly..

Re: qemu emulator for the mini2440

Yes you can help I'm sure; I don't know qemu either you know. it's the first time I hack it :D look at the source, it's mostly in hw/mini2440* hw/s3c* hw/dm9000* etc, it is in fact rather easy to understand if you understand the s3c, the kernel etc... you can understand what is happening by looking ...

Re: qemu emulator for the mini2440

Have not tried the SD yet. I think I need to map the IRQ properly for it to work, I'll try that next actualy, that could help a lot until I figure out the nfs..

Re: [ANN][MINI2440] modern kernel (2.6.29-rc6) git repository

Well as I said I dont have a 7". I tried to get one cheap from esky but he went AWOL, and the armwork's one is in the post.

Have you set the jumper to 3.3 on the board ? I think it's needed for the 7", feeding it the other voltage might damage it.

Otherwise, I'll look when I get one..

Re: [ANN][MINI2440] modern kernel (2.6.29-rc6) git repository

You need to pass "mini2440=1tb" for the kernel to configure itself for a 7". Do read the early boot messages of the kernel you can see what values represent what size.

I haven't tested the 7" support in hardware tho, I don't have one yet -- should work tho
