Hi,

I have opened the memory browser and put the location 0x80000000.I got the register values for the DDR.Many of the blocks are in red color.when i am changing the value either in red or black color block of the register memory CCS is getting closed.I have not loaded any GEL file.I am using only one ddr memory with processor am5728.Please guide/suggest some way out.Is GEL file correction is must?

Hi,

I am not entirely sure what you mean by CCS is getting closed. Is it locking up or the address is simply not being shown properly?

Since you are trying to access the DDR memory region (0x80000000 belongs to its data space), but is not using any GEL and (supposedly) has no code previously loaded, the memory read by the device will be random - the EMIF peripheral is not initialized.

In this case, you can try to either load code that initializes the EMIF and DDR or use the GEL file - these files are automatically added to the board configurations in CCS, such as IDK_AM572x, GPEVM_AM572x, etc.

Hope this helps,

Rafael

Hi,

Thanks for the reply.

I have attached the XLSM (From EMIF TOOL) and DDR datasheet(MPN:MT41K256M16TW-107IT:P).Can somebody verify the same (.XLSM) ?

What all the changes i have to do in GEL files? I have used only ONE DDR.

Please guide for the same.

Hi,

Please apologize for the delay; I missed your last reply.

I notified the device experts and they should provide additional insights about your last questions.
