<br><font size=2 face="sans-serif">Hello,</font>
<br>
<br><font size=2 face="sans-serif">We have a working RAM version of U-Boot
for MPC8260ADS type customs board. We load the "u-boot.serc"
by the TRACE tool and when run from the trace tool it gives the U-Boot
prompt. I am giving a snap of the CMM file which actually loads the u-boot.serc
to the memory. </font>
<br><font size=2 face="sans-serif">Our HRCW is "80 52 72 45".
As per my understanding this values are stored in the flash. The flash
is adress starts from 0x0.</font>

<br>
<br><font size=2 face="sans-serif">My question is.</font>
<br>
<br><font size=2 face="sans-serif">What the places we need to look into
to convert this RAM version of U-Boot to ROM/Flash version of U-boot. The
objective is when power on the u-boot binaries stored into the flash/ROM
should be executed and give us the boot prompt. </font>
<br><font size=2 face="sans-serif">I think I need to change the HRCW.</font>
<br><font size=2 face="sans-serif">and the job done by the above CMM file
should be done by the u-boot binary, so some part of the RAM version u-boot
need to be modified to do this. Is there any specific place in the u-boot
tree where we need to make change which does the job of the CMM file? </font>
<br>
<br><font size=2 face="sans-serif">Any help in this regard will be helpful.
</font>
