I have a problem probably with my arm toolchain but maybe there's something other that I do wrong. I have Chinese made dev board qq2440 using Samsung s3c2440 ARM9 uC. I'm using Ubuntu x86 with native gcc(4.3.3) and cross-compile version arm-unknown-linux-uclibc-gcc (crosstool-NG-1.3.2) 4.3.2
I followed tutorials from http://blog.leshak.ru/english/pages/how-to-install-u-boot-linux-2629-rootfsjffs2-busybox-1132-into-nand-qq2440/ and used Leshak's kernel patches for that board. Problem is that his binaries work perfectly and mine don't...
I communicate with my board over RS232 (serial port) and I have serial terminal configured on target Linux. I use Leshak's uboot image. To configure my kernel I use following command line:
qq2440> setenv bootargs 'noinitrd root=/dev/mtdblock2 rootfstype=jffs2 rw console=ttySAC0,115200'
For target I use vanilla Linux sources version 2.6.29, with patches created by Leshak. I don't honestly believe that this will ever be supported officially by Linux as it's not mainstream product.
My kernel image starts booting up, but it probably changes bandwidth (or CPU frequency) to some non standard value (tried all standard ones already). Instead of dots indicating loading kernel into memory I've got only trash instead. Unfortunately it doesn't probably finish the boot process as the network interface nor file system don't come up. So I figured out that it panics somewhere in the middle.
Any ideas what should I do next?
Thanks & regards,
