Re: [Gumstix-users] Boot Loader on the "Classic" gumstix

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

Benny,

there were a whole bunch of changes from 1.0.0 to 1.1.1 -- I took the 
opportunity to clean up Gordon's original code.  There aren't really a 
whole lot of timing-sensitive areas in the u-boot code.  If you let it 
run w/out single-stepping in JTAG, what happens?  Just hangs?  While 
it's hung, what happens if you then take a look using JTAG to see what 
it's doing?  Could you dissassemble a few instructions around the PC 
where it's hanging?  If so, then it should be easy to figure out where 
in u-boot it's sticking, using arm-linux-objdump -S u-boot on the 
u-boot which hasn't had all its symbols removed.
