Guide to ASTRO Digital Radios
or EEPROM which stores the CSD. At the time this guide was written, this statement applies only to
Motorola Inc. ASTRO series radios. ASTRO25 radios are not manipulated using the same process.
More is discussed later in the guide.
The first version of host firmware ever released is unknown. The earliest version I’ve come
across is cp_D01.04.00. Another confirmed VSELP revision is ap_R03.20.01. are internally dated as
©1996 by Motorola Inc. I’m inclined to believe there’s much earlier firmware than this.
The prefix designations of cp and ap have no known meaning, however it has been noted ap
always prefixes VSELP host firmware.
The R means RELEASE, which is stable firmware intended for the public.
D means DEVELOPMENT, which signifies the firmware is intended for a special application or a
customer-specific issue which may or may not be in the testing phase.
The first number in the firmware version signifies the major release. It also indicates which type
of codec (DSP firmware) it’s compatible with. Example: R07.71.00. The 7 indicates it’s compatible with
the IMBE DSP firmware. More on this is discussed later.
Let’s discuss major firmware versions. The following chart identifies significant information
associated with each ASTRO release. For the purpose of conveying factual information, the guide
covers firmware from major version 3 and up, as little is known about earlier releases. These tables do
not apply to ASTRO25-family firmware releases.
