Hello colegues, Few days ago I was given mini2440 to play around with. Now I have working u-boot and I am trying to run linux on this board (128Mb version). I was trying few kernels and filesystems but have some problems while booting. Linux is starting but after huge amount of some strange errors (mainly about unused memory). Can anybody upload somewhere working kernel and filesystem for this board?
Why get what is available off the Downloads page? Which kernels have you tried?
Why NOT get . . .
Ok, one extra question - which kernel should I use for board without LCD screen?
Sorry, can't answer that one. Out of interest I disconnected the touchscreen (n35 on a 64M mini2440) and after waiting a minute or so I get the login prompt on minicom. So, my guess is that a working kernel with any touchscreen configuration would work without a touchscreen.
OK, will try that later at home...
If you are using SD card for rootfs, use ext3 or ext4 (and compile kernel with support for them).
.... and the environment variables via u-boot
The problem is that I am trying to use kernel downloaded from this site. I have no possibility to build custom kernel (no possibility = no knowledge). after booting u-boot I am trying to load kernel image by commands: # dynenv set 40000 # nand erase kernel # mmcinit # fatload mmc 0:1 0x31000000 zImage_X35 (or any other from downloaded archive) # nand write 0x31000000 kernel # setenv bootcmd nboot.e kernel \; bootm # saveenv # reset and the error is: Loading from NAND 128MiB 3,3V 8-bit, offset 0x60000 ** Unknown image type Wrong Image Format for bootm command ERROR: can't get kernel image! I've found other kernel on net, but while booting I have a lot of sth like this: ... Empty flash at 0x0114bffc ends at 0x0114c000 Empty flash at 0x0114fffc ends at 0x01150000 Empty flash at 0x01153ffc ends at 0x01154000 Empty flash at 0x01163ffc ends at 0x01164000 Empty flash at 0x01167ffc ends at 0x01168000 Empty flash at 0x0116bffc ends at 0x0116c000 Empty flash at 0x0116fffc ends at 0x01170000 Empty flash at 0x01173ffc ends at 0x01174000 Empty flash at 0x01177ffc ends at 0x01178000 Empty flash at 0x0117bfb0 ends at 0x0117c000 Empty flash at 0x01183ffc ends at 0x01184000 Empty flash at 0x01187ffc ends at 0x01188000 Empty flash at 0x0118bffc ends at 0x0118c000 ... after a while (few minutes) system is running, but those messages cannot be any good :/ PS. for root i've used file gpe-image-micro2440.jffs2
Looks like you are trying to load a zImage with u-boot. This just doesn't work! You need an uImage. u-boot = uImage Supervivi = zImage What does "after a while (few minutes) system is running" mean? Have a look at the wiki for help in getting things going.
Ok, so I've got running system with u-boot and uImage found on the net. Maby I will try downloaded zImages with supervivi. "after a while" is about 1000-1500 lines of "Empty flash at....".
Good. So, after "1000-1500 lines of ..." the system starts running. Doesn't sound right to me. However, you are on your way now. The next hurdle is just ahead. Good luck!
i need uimage for x35
