(5282evb) internal FLASH program using the External RAM

Hi,

Anyone has worked with a 5282 running from internal FLASH using the external RAM for dynamic data. If so how do you do that?

Well let me refine my previous post.

The MCF5282evb is running a program from the internal FLASH. It uses the external SDRAM for its data. THe program has no problem starting with the BDM emulator on, but the somehow fails to execute with the BDM emulator off. In other words, hitting reset after the FLASH has been programmed does'nt start the program. Instead it carshes somewhere before startup code.

Any hints?

Hi 0xFB,

I had the same issue.

1. Set SW1 on the M5282 properly: SW1-8 set OFF, SW1-9 set OFF

2. Try the lcf, mem, cfg and xml (for CW Flasher) files that I attached.

The difference of my case and your case is that I use only SRAM and Int. Flash.

You should just only change two lines in the lcf file (actually commented) for your case.

Best regards,

Andrey Butok
