tms320f2808 - Intel hex format, data records

Manju

Other Parts Discussed in Thread: TMS320F2808

hello

I am using c2000->cgtools->hex2000.exe to generate .hex from .coff / .out file using -i (intel format) and -o for outputting (.hex file). The hex file has the extended Linear Addr rec which specifies the ULBA addr according to the Intel hex format (this part is fine). But the data records that are generated are 8-bit data. But the tms320f2808 has a word format memory. This makes to write only a byte of data on to the memory location, wherein i should be writing a word on to memory location.

Is there something i am missing while generating .hex file. Or what is the procedure to generate a 16bit format data records using TI tools.

Thanks

If you are using the default hex converter options, you are likely generating 2 hex output files. This is because the F28x has a target width of 16 bits while the default output width of the Intel hex format is 8 bits, so the executable is converted into 2 intel hex files, with alternating bytes in each file.

To generate one Intel hex file, you can use the -romwidth=16 option.

The C28x Assembly Language Tools Users Guide, http://www.ti.com/lit/spru513, section 11.3.3 has more details on this.

try with these options:

--memwidth 16
--romwidth 16
-i
-byte
