TMS320C6745 DSPBIOS problem

Hi,

I used OMAPL137EVM with CCS4 and DSPBIOS. Now I try to launch my own board based on TMS320C6745BPT.

I have communication via XDS100v2 with CCS4. My board doesn`t have external memory. I run easy program that

blinks LED`s via GPIO in main();. In doc. SPRS377D rev. 082010 I found that GPIO start address differ from C6747-

0x01E25000 and 0x01E26000. Is it truth? I use evmomapl137.h and GPIO work properly (0x01E26000).

Next I tryed to run DSPBIOS using evm6747 platform template. I deleted SDRAM and L3_CBA_RAM, created

CLK0 (Timer1) and TSK0 driven by PRD. My program hung up, cant start TSK0 and CLK0. What do I wrong?

Best regards.

The GPIO offset for both devices is 0x01E26000.

For the second part of your question, you should ask in the DSP/BIOS forum. The 6747 and 6745 processors are compatible so the same code should work on both given that you move all memory out of the SDRAM region correctly.
