Hi, I'm working on a project in CCS 2.0 (C5402 processor). After building procedure, an executable file named bootload.out is made. With File/Load Program... everything works fine. Now I need to load a file into memory with another loader (another processor loads data from Flash memory into DSP memory thru HPI). Is a file format for loading into RAM the same? Or should I convert .out file with a dsphex utility, like it is described in: http://www-s.ti.com/sc/psheets/spru018d/spru018d.pdf When I do everything like it says in http://www-s.ti.com/sc/psheets/spra235/spra235.pdf, the dsphex utility won't do anything and it's output is: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ D:\ti\MYPROJ~1\bootload>dsphex command.cmd DOS/4GW Professional Protected Mode Run-time Version 1.96 Copyright (c) Rational Systems, Inc. 1990-1994 DSP Fixed Point Hex Converter Version 6.49 Copyright (c) 1987-1994 Texas Instruments Incorporated "command.cmd", line 1: warning: illegal input file type: bootload.out ignored >> no input files (aborting) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ I downloaded this utility from: ftp://ftp.ti.com/pub/tms320bbs/c5xfiles/dsphex.exe I am grateful for every response to my issue. Thank you. Kruno Sekovanic |

CCS 2.0 and DSPHEX.EXE (conversion utility)

Try using HEX500: c:\ti\c5400\cgtools\bin\hex500 -romwidth 16 -e {your executable start address} -m2 bootload.out This will generate two Motorola SRecord files. One contains the program code and the other contains the initialised data. You will then have to convert the SRec files into some data format that your loader likes. In my case I turn them into a header file and use a simple routine to decode it and load it into the DSP The attached program addterm.exe will turn the two files into a single C header file with the two Srecs defined as Static char arrays. Usage: addterm {.out filename without extension} {header file name without extension} e.g addterm bootload bootcode will produce a header file called bootcode.h containing two const char arrays, called bootloadProgram and bootloadData. I am afraid that I am not allowed to share my srec reader code. Les > Hi, > > I'm working on a project in CCS 2.0 (C5402 processor).
