Developing a universal module

It's rather strange, the V202 protocol doesn't seem to work, but KN protocol works perfectly. Both V202 & KN use NRF24L01. I don't understand why V202 doesn't work. When I tried to Bind under V202, it counted down from 3 seconds to 0 and stayed at 0. That is, the bind screen never exited. I remembered it would exit the Binding screen when not using the Multi-module. Any hints?

[EDIT]
BTW, I'm using the latest nightly build. Can this be a software bug?

Sometimes, I have to turn on/off 2 or 3 times the devo to manage to bind

I've turned off & on more than 20 times and still couldn't get V202 protocol to work. When you bind with V202, does the countdown screen exit by itself? Or stays at 0 second until you manually exit the screen?

Putting it back to multi-module and V202 didn't work. The thing that puzzles me is why KN protocol works; while V202 doesn't. They both use the NRF24L01 module. I have triple checked all my connections for short and cold solder; and there doesn't seem to be anything wrong with the connections.

More testings:

Case 1:
In the hardware.ini file, if I only enable multi-module with NRF24L01 (A7105 & CC2500 disabled), Devo 7e will boot up with a message saying "Missing Modules: CYRF6936".

Case 2:
In the hardware.ini file, only enable MM with A7105, Devo 7e will also boot up with "Missing Modules: CYRF6936".

Case 3:
In the hardware.ini file, only enable MM with CC2500, Devo 7e boots up normally.

Do you have the 1.2/1.3/1.4 version ? How did you flash the ATTiny ? which version you have ?

avrdude -p t24 -c usbasp -e -U flash:w:avr.hex
avrdude -p t24 -c usbasp -U lfuse:w:0xe2:m -U hfuse:w:0xdf:m -U efuse:w:0xff:m

When I had installed the first module A7105 into the MM (NRF24L01 & CC2500 are not installed at the time), I tested it with Devo 7e and it worked and there were no missing CYRF6936 message. I only had that message when I installed all 3 modules, but only enable A7105 or NRF24L01 alone.

I've the v1.3 MM ordered from oshpark. I only have a Devo 7e, so I flashed my ATTYINY24A-PU with Usbasp. The AVR.hex was downloaded from the download section of this forum which labelled Rev3. The flashing instructions was obtained from wiki as follows.

avrdude -p t24 -c usbasp -e -U flash:w:avr.hex
avrdude -p t24 -c usbasp -U lfuse:w:0xe2:m -U hfuse:w:0xdf:m -U efuse:w:0xff:m

I'm out of ideas.
