Re: [Gumstix-users] Boot time

[Craig H. <cr...@gu...>]

Doing some basic timing tests once in linux, it actually looks like I  
might have just sped up flash reads by about 2x in linux -- at least,  
doing

date;dd if=/dev/mtdblock1 of=/dev/null;date

gives 4 seconds with the old u-boot, 2 seconds with the new u-boot  
for 4MB flash.  I think I killed the u-boot on my XM gumstix here so  
I won't be able to time that with the new u-boot under linux until I  
JTAG it.
