SDRAM narrow mode

Other Parts Discussed in Thread: OMAP-L137

Hello.

This is my setup:

- CCS v5

- C6747 DSP on an OMAP-L137 EVM

- DSP/BIOS

I would like to be able to switch to narrow mode (NM) on EMIFB/SDRAM to be able to compare the performance with my current 32-bit mode.

I understand that you need to set bit 14 of the register SDCFG. My question is: when/where do I do this?

I have seen it done in the GEL-file, but isn't that file just used together with the debugger? Surely, if I eventually want run without a debugger I need to set the register up elsewhere? I sort of assumed it would be done in the .tcf file, but I haven't managed to figure it out.

Any ideas?

Thanks,

Anders.

Anders,

Do it in the GEL file. Then you can compare your performance with your current 32-bit mode.

Later, when you are building a standalone product, you will learn about the bootloader and review the Bootloader Application Report to understand how to use it.

Regards,
RandyP

Thanks. I'll start with the GEL file and move on to the bootloader later then.
