Hi,
I'm trying to boot a DA830 EVM with TI's U-Boot (1.3.3) I have the
davinci kernel git tree and using CodeSourcery G++ Lite 2009q1-203, I
did:
make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi-
da830_omapl137_defconfig
make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- uImage
This gave me a uImage file [Image Name:
Linux-2.6.31-rc7-davinci1-06494-] that I have tftp booted with these
settings:
setenv nfshost x.x.x.x
setenv serverip x.x.x.x
setenv rootpath /my/OMAP/nfspath/root
setenv bootfile uImage
setenv bootcmd "dhcp;bootm"
setenv bootagrs "console=ttyS2,115200n8 noinitrd rw ip=dhcp
rootfs=/dev/nfs nfsroot=${nfshost}:${rootpath},nolock mem=32M"
It downloads, uncompresses, and says, "starting the kernel" and that's
that. I dumped __log_buf and unmangled the output to get:

[snip more unwinding output]
There is only one call to bug() in davinci_timer_init(), so I guess it
must be bugging out on
timer_clk = clk_get(NULL, "timer0");
BUG_ON(IS_ERR(timer_clk));
Should I be using this new a kernel? Maybe I messed up the
configuration:- they are basically the same settings I used for the TI
supplied kernel though, which boots fine. It a very old kernel though
2.6.18 and a bit.
Any ideas what I have done wrong?
Thanks,
Nick.
