hello all

 

i am facing a perculiar problem when i try to run linux on the blackfin

 

the kernel compiled and everything went smoothly until the actual boot on the blackfin

 

i configured the Bfin with autoboot on power up,

 

the problem:when i power up, it counts down to 0 and does nothing and only boots up when i do

 

"run bootcmd"  in the GtkTerm

 

after boot up, i have another problem, it keeps spitting garbage after every command

 

his has serious impications when i tried to receive input from user

 

can anyone suggest a solutions to these?

 

thank you in anticipcation

What is your uboot release? Please check your uboot auto boot env parameters.
