Kernel hangs at Starting kernel...

Hi,

I am facing an issue on a custom dm365 board. I am trying to boot through ram. I can successfully get to the u-boot prompt using the slh_dm36x utility. 

Then, I copy the kernel into ram using ymodem protocol through UART 0.

But after copying the kernel, when I give the

#bootm <addr in ram>

command, it hangs at Starting kernel...

The exact output is as follows:

DM365 UBOOT:>bootm 0x80700000                                                    
## Booting kernel from Legacy Image at 80700000 ...                             
   Image Name:   Linux-2.6.37_DM365_5.1.0+                                 
   Image Type:   ARM Linux Kernel Image (uncompressed)                          
   Data Size:    3783232 Bytes =  3.6 MB                                        
   Load Address: 80008000                                                       
   Entry Point:  80008000                                                       
   Verifying Checksum ... OK                                                    
   Loading Kernel Image ... OK                                                  
OK                                                                              
                                                                                
Starting kernel ...

And then, no response comes from the DM365.

The same kernel boots without problems when loaded from nand.

Could someone please help me understand what is going wrong?
