RSP720 throwing "Unable to locate DDR I or DDR II module" error after reset from ROMmon mode

Hi,

 

Our one of C7609-S routers got crashed and stuck in ROMmon mode. We tried resetting RSP720 but giving the error of DDR SDRAM not found. An error of "Software Forced Crash" also visible on the screen. The router is running with 12.2(33) SRE8 IOS version. What could be the possible reason of this behavior and the next remediation action?

rommon 12 > confreg 0x2102

 

You must reset or power cycle for new config to take effect

rommon 13 > reset

Create a new thread. 

Plug a console in and reboot the supervisor card.  Post the entire boot-up process.  We want to see what is going on.
