I am pleased to announce very fast boot for dm365.It takes 0.5 (half of a second) from kernel initialization (not including u-boot and kernel unzip) till command line prompt.
Download ready uImage with root FS and test it: http://www.makelinux.net/ti/fastboot/
Boot time measured by printing /proc/uptime from boot script.

When I burned ubl
and uboot on nand flash with small block size (hynix 64MB) using
DM35x_FlashAndBootUtils_1_50 through serial port, I got error message "No
good blocks in allowed range". I used a new nand flash. So please tell me
it is why. thanks a lot.
In reply to YHLShareware:
@Mark/YHLShareware - you probably posted to the wrong topic.
on topic: nice value - according to the wiki there were already several efforts (total boot in less than 1s) in speeding kernel boot up. the overall value from power on until the user can launch its application is in fact the more interesting one. (and its as well dependent on the size of the kernel image to load and unpack, so a sole linux kernel boot value does not tell anything)
In reply to Alexander Stohr:
Time of loading kernel from flash depends from flash type NAND/NOR, throughput, UBL/u-boot configuration and eventually kernel and FS size.

In reply to Constantine:
i want to make a nfs file with busybox1.13.3 on platform DM365.but it can not run the /sbin/init.
if i replace the /sbin/init with the montavista/nfs/sbin/init,it is right.
my cross_compile of busybox is arm-linux-gcc3.3.2.
and my kernel is arm_v5t_le-gcc.
can you tell me why the busybox/sbin/init can not run.
is it the compiler can not match?
and can you tell which kind of busbox should i use to make?
