Hi I'm new in this group.I work on TMS320vc549 for my final project. I have (CCS v.2) and i don't know how convert *.obj files to *.hex files. And If i want to use HPI for first boot, what i must to do? I design a board with c549 and i want send data to TMS320vc549'DARAM With MC-8051.I want know if i use this method to boot my DSP, it's important to use Level shifter for convert 5v-TTL(8051) to 3.3v(I/O DSP).and if i dont use level shifter for this it's possible to damage my DSP chip. Thank you. Amin |

Dear Amin,
TI have prepared the tool named by HEX500 for converting the *.obj and
*.out file to a selected HEX format. HEX500 tool gives the input files and
create a HEX file as an output according to its cmmand file. Please note that
the HEX500 command file is different with the CCS project command file.
For more information see the SPRU102E, TMS320C54x Assembly Language Tools
User's Guide, Chapter 10: Hex Conversion Utility Description.
Best regard,
Morteza Alizadeh

A level shifting bus switch will work. With 8051, you should be able to treat HPI as SRAM and get it to work. You can tie /HDS1 and /HAS high, use an 8051 strobe connected to /HCS and a high address line (inverted) connected /HDS2, and use /MEMW as HR/W. The one thing to be careful of would be monitoring HRDY to make sure HPI is ready for additional transactions. It is possible to make consecutive HPI transactions too fast, although with 8051 that's not very likely :-) -Jeff |
