I'm using the TASKING EDE C166 tools and need to disassemble a pure
binary image. What would be the best way to proceeed? I tried the
normal disassembler but it only disassembles obj output files.

Very simple:
convert the binary image into a hex file (google search: srecord)
and then use the Crossview Pro Debugger Simulator.
It also has a dump disassembly function.

It appears the debugger still wants an obj input file.... I have a hex
file from the binary file but when loading this file the EDE says
"Cannot download from given format". I used -Ascii_Hex as output format
from command line in srecord.

You will have to start Crossview Pro and then select "Download Application".
Crossview Pro does load hex files.
You will have to disable the options:
Verify download
Use map file for memory map

I originally tried unchecking verify and use map checkboxes.

Maybe you have a tiny hex file that I can try to load ?

My target processor is Infineon C166S.

I get 'invalid imagefile' message.

The starting content of hex file looks like:

(02 as binary) fa 02 70 2d 00 00 00 00 00 00 00 00 00 00 00 00 32
35 2e 31 30 2e 30 32 31 35 3a 31 39 3a 31..............

the hext content matches the binary image, I assume the leading 02
binary
is a spec for the HEX content format.

Is this format correct ?

Doesn't look like Intel-HEX. Each record should start with
a semicolon (see 'Intel-Hex format' appendix in assembler
manual). If you're using srec_cat as advised by Jan then
try this:

srec_cat hello.bin -binary -output hello.hex -intel

This should result in a proper hex file.

That one worked.... Thanks.

I need to save the disassembly into an assembler source file, and don't
see any easy way of doing this.

R Dunn

You can do so by logging the output from CrossView Pro's
command window:

(1) >> disassembly.txt
(2) dis 0x2f4,#10
(3) >> c

In here (1) enables redirection to disassembly.txt, (2)
does the disassembly and (3) closes disassembly.txt.
