missing NRF24L01 after update to nightly

I've been using devo 10 with deviation-devo10-v4.0.1-65084ff with A7105 and NRF24L01 without any problems. I can fly my WLtoys V977 without any problem. It means the connections of NRF24L01 should be correct.
However, after I update to latest nightly (deviation-devo10-v4.0.1-c3007aa), it prompts me missing module NRF24L01.
Is there any change in the wiring of NRF24L01 with the recent nightly? Or more thorough check?
Thanks guys. I really enjoy this deviation tx, I just cannot understand where my problem is

I installed a NRF24L01 in a Devo 7e as the first module according to the instructions on the hackmods page. It worked fine with all I flew. Later, I installed an A7105 module and used the remaining pin. The A7105 was not recognized until I swapped the position of the two modules pins on the board, and in the hardware.ini file. I was using a Nightly Build, probably 06/08.
I am always paranoid about bridged connections, and I checked the board well before I fired up the A7105 and before I swapped the pins, so it had a strong appearance of a SW conflict.

The 4.0.1 version does not check at power-up if data can be read from the nrf, and I think only the yd717 protocol requires reading from the module. Yes, check your connection to MISO.martinwh81 wrote: Does it mean the previous build doesn't need the data from MISO? but it works with previous build. I think i use the build from feb 2015. So i need to check my soldering to MISO right?

Your configuration is what had before I swapped the TCK/TMS and changed the .INI. It is possible that there is no sensitivity, and there was an unnoticed error in my .INI file, which I inadvertently corrected when I changed the .INI file, after swapping the pins. I don't believe there was a problem with the wiring on the board.
