Some question about MPC8313erdb

Freshman · ‎12-03-2012

hi

lately,I was doing something about the u-boot and kernel with the MPC8313erdb,I have done as the following as the user‘ manual ,but at last ,I couldn't enter the linux enviroment:

I don't have an answer for the hang you're seeing -- it would need to be debugged -- other than a suggestion to try the latest upstream code rather than the old BSP.

However, RAM contents are not retained across a reboot. You can't just "bootm 200000 1000000 400000" after a reboot and expect it to work; you need to load the images again.

HI

Scott wood

yes,you are right!

for the first question: I should enter with "root"+"enter key" It will be ok!

for the second question : the files had been donwload to the ram and burn to the flash ,at the first time ,I can enter the u-boot

cmd as "=>bootm 200000 1000000 400000" ,but if I reset ,the problem did come ,because ,I should enter the cmd as "=>bootm fe100000 fe300000 fe700000"! boot it from the ram!

Now, It's OK！
