Hi all,
I am using montavista linux professional edition 4.0.1.
Initially I tried booting the linux elf image by downloading it into RAM
using the USB JTAG.
Linux is comingup properly and I am able to see the login prompt.
Now I am trying to boot linux from the u-boot. I will download the u-boot
image into the RAM and run it.
From u-boot prompt I downloaded the kernel image and run it. Boot
messages are given below. I enabled debug messages in u-boot.
After analysing the kernel booting by setting hardware breakpoints in xmd
we came to know that it is hanging in the funciton mmu_mapin_ram()
function. Help me in chasing this... Thanks in advance
