devo7e install both A7105 and NRF24L01 was created by yuqiang

hi guys,
I installed A7105 and it worked well(on A13), but after I installed NRF24L01 on A14 and setup TX.ini, A7105 does not work!
Devo7e can not boot up, it seems blocked at A7105 init, If I remove the connection of VDD on NRF24L01, devo7e works well with A7105.
That means A7105 and NRF24L01 can not be installed together?
Thanks for your help~

PS: NRF24L01 module works well with STM32 dev board.

Is you A7105 module connected to TMS pin and NRF24L01 module connected to TCK pin on main board?

Can you list all other connections of NRF24L01 module?

Both modules can work together. Check connection MOSI and MISO lines, probably you can interchange that lines. At any case it seems you have some hardware conflict.
