Known Differences between TI EMK boards and A2530 Modules

=A2530 MODULES DO NOT CONTAIN THE 32 KHZ CRYSTAL= The A2530 modules do not contain the 32 KHz clock crystal that is included on the TI CC2530-EMK and CC2530-CC2591-EMK boards. If needed, the crystal can be added externally, as the pins are brought out on the module. This applies to both the A2530R and A2530E modules.

On the Anaren A2530 BoosterPack board, the pads for the external crystal and associated capacitors are there. So that the crystal can be populated on the BoosterPack board.

The software that comes preloaded on the A2530 modules does not require the external crystal.

If reloading the module with Z-Stack software, be sure to rebuild with the symbol "OSC32K_CRYSTAL_INSTALLED=FALSE" defined in the project options for the C/C++ Pre-Processor if you do not have an external 32KHz clock crystal.

=A2530E MODULES USE CC2530 P1_3 INSTEAD OF P1_4 FOR CONNECTION TO CC2591 EN PIN= The A2530E modules (with the CC2591) use the CC2530 P1_3 pin for the CC2591 EN signal. Whereas the TI CC2530-CC2591 Reference Design (EMK) uses CC2530 P1_4 for EN. This connection is internal to the A2530E module and cannot be changed in hardware. So a software change is required to operate it properly.

The software that comes preloaded on the A2530E modules has been built to use P1_3 correctly.

However if reloading the module with Z-Stack software, there is one change needed to move the EN signal from P1_4 to P1_3. Plus of course, the software to run the CC2591 needs to be enabled. The following steps should accomplish this:


 * Define the symbol HAL_PA_LNA in the project options for the C/C++ Compiler Pre-Processor.
 * Define the symbol ANAREN_A2530E in the project options for the C/C++ Compiler Pre-Processor.
 * Modify the file mac_radio_defs.c in the MAC -> Low Level -> System project folder:

Change the line that reads:

OBSSEL4 = OBSSEL_OBS_CTRL1;

to be:

OBSSEL4 = OBSSEL_OBS_CTRL1; OBSSEL3 = OBSSEL_OBS_CTRL1;
 * 1) ifndef ANAREN_A2530E  // the TI EMK P1_4 setting
 * 1) else                  // the Anaren A2530E P1_3 setting
 * 1) endif
