HPI question | TMS320C55x | DSPRelated.com

Technical discussions about the TI C55x DSPs (including the c5501, c5502, c5503, c5507, c5509, c5510 and OMAP5910).

Hello everyone, I use Hpi port to boot DSP5510 and exchange data between host and 5510. It works OK. However, when I connected DSP with emulator through JTAG port and start CCS2.1 without running any programe, the host failed to write and read DSP through HPI port. But at the same condition the Host can boot DSP5409 and write/read its memroy correctly. Can anyone gave me a clue? Thanks in advance. mayu

Hi Mayu, I assumed you had able to bring up the 5510 through emulator. Now as for ur host processor & DSP interfcae through HPI. take care of the following steps 1> Make sure ur cmd file startup the boot code from 0x10000h( byte address) while loading the code through CCS. 2> The 5510 should up & running through emulator only first. 3> All the EHPI interface software configuration wriiten in the host code should be properly executed. Then u will be able to see & write data from the host to the DSP. I guess u r using 5510 silicon verion 2.0 or above.
