Debugger not showing external SRAM contents

Hi All


We are using K60F128M CPU with external SRAM interfaced at address 0x60000000.

SRAM is working properly and I am able to store and retrieve values from the program.

But when trying to see the values loaded on SRAM in the memory view of  debugger, it just shows "?????".

Then, I modified the memory configuration file(.mem) as below to match our setup.

After that when I try to start debugging its getting timed out saying "Debugger has lost connection to the target".


Any idea about how to solve this ?
