View Memory in Codewarrior IDE

[josemone]

Hi,

     I am using Codewarrior for Coldfire v7.1 (Windows hosted) and debugging my target via P&E USB Coldfire Multilink debugger. The target is M5485BFEE Fire Engine board on top a custom baseboard having a Dual Port RAM chip. This chip is interfaced to the Fire Engine board via the FB_CS3# chip select.

    Now the problem is I am able to read and write to the Dual Port RAM chip but the same is not updated in the Memory Window (Data > View Memory in the Codewarrior debugger mode). It consistently shows 0xBA everywhere in the memory region of interest.

What I am interested to know is, whether any thing additional has to be done to bring my Dual Port RAM contents to this memory window ? What is the purpose of .mem and .cfg files which are present for the on-board SDRAM and Flash chips ?

regards,

Joseph

It sounds like address range used to access your RAM is defined as reserved in your memory configuration file (.mem).  Check out the Memory Configuration Files section of Targeting_ColdFire.pdf.
