Hi, I currently have a c5402 booting via serial (code & data loaded from the serial port), however i have now moved to the c6415 and am looking to boot the processor via a pci interface. Does anyone have any information on the best process to achieve this ? Thanks in advance. Regards. -- Steve. |

It was quite simple: (Assuming that the PCI BARs are configured by a host operating system, we used linux) Do a warm reset (set bit 0 in register HDCR in BAR1). You must wait at least 16 DSP clock cycles before accessing the DSP again. Write code to the memory (BAR0). We converted the .out file to srecords with the TI tools and had a simple srecord parser to download. The window to the DSP memory is 4MB and starts at 0x00000000 after reset. If you want to download code to external RAM you have to move the window (there is a register in BAR1 for that) Do a DSPINT (set bit 1 in register HDCR) /Regards, P Ligander |
