ADI ADSP2181 and 2185, code compatible??

[DF]

If I generate the executable code from Release 5.1 compiler, would it
run on 2185? The code only use internal PM and DM so the address
space should be identical. Any one has such kind of experience.

I am having trouble in running a piece of code which generated by
Release 5.1 tools and the code is running fine on 2181 and 2183 but
not 2185.

Any idea or comment?

The 5.1 tools work just fine with the 2185. We include the 5.1 tools with
our DSP-8300 dev kit which uses a 2186M (ADI did not copyright these
tools).

There are a couple of shared pins on the 2185 that were separate on the
2181. I onced used an unused external interrupt as a software interrupt
for a 2181 based project. When I translated the design to a 2185, I got
burned because the pin was shared with another function.

There is very little difference from a programming point of view between
the 2185 & 2181. Are you sure your 2185 is working correctly? Maybe you
have a hardware problem.

2185 is 100% code compatible with 2181. However 2185 has several
hardware anomalies which may cause trouble. Take a look at errata
sheets.

Thanks for all the response. Yes, it was a hardware problem. The
2185 is fully code compatible with 2181 and we can still use the
Release 5.1 tools.
