imx283 linux3.18 can't startup correcttly

[nxpaudience]

Hi, I can't start up the kernel(linux3.18) on imx283.

i have open the CONFIG_DEBUG_LL and could use the printch to output some stuff on the serial port, 

but, after it enable mmu, 

mcr p15, 0, r0, c1, c0, 0 @ write control reg
mrc p15, 0, r3, c0, c0, 0 @ read id reg

i can't use the printch anymore, 

and i find that, the kernel don't run to b start_kernel, 

now , i don't know how to debug this,

Hi dong liang,

Is your board you designed yourself? About the i.MX28 there is no updated BSP for it. But in the newest BSP stucture you can choose the i.MX28 dts file. Here you need to porting BSP yourself. If the board is designed yourself, you can run the BSP we supply on our website. If the old BSP work fine, you can try the newest. Hope this can do help for you.
Have a great day,
Rita
