<br><font size=2 face="sans-serif">Hi all,</font>
<br>
<br><font size=2 face="sans-serif">I am using montavista linux professional
edition 4.0.1. </font>
<br>
<br><font size=2 face="sans-serif">Initially I tried booting the linux
elf image by downloading it into RAM using the USB JTAG.</font>
<br><font size=2 face="sans-serif">Linux is comingup properly and I am
able to see the login prompt.</font>
<br>
<br><font size=2 face="sans-serif">Now I am trying to boot linux from the
u-boot. I will download the u-boot image into the RAM and run it.</font>
<br><font size=2 face="sans-serif">From u-boot prompt I downloaded
the kernel image and run it. Boot messages are given below. I enabled debug
messages in u-boot.</font>
<br><font size=2 face="sans-serif">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()</font>
<br><font size=2 face="sans-serif">function. Help me in chasing this...
Thanks in advance</font>
