Microcontroller and DSP code revisions
The test limits described in this document may depend on which revision of either the mi-
crocontroller or DSP code is present.
The microcontroller must have successfully booted.
3.8.1 Issue the following command:
tv
Within 500msec, expect a text string similar to the following.
3500/3600
>
The first four-digit number is the microcontroller code version. The second
four-digit number following the "slash" is the DSP code revision number. Ig-
nore the two trailing zeros on each number -- e.g., the string "2300" indi-
cates version 23.
Only certain combinations of uC / DSP firmware revisions are valid for new
production. These valid combinations are listed in the table below:
3.8.2 For service rework, any firmware combination that meets the following criteria
is valid:
uC version >= 35
DSP version >= 35
