NRF52810 don't work at BLE mode but work at without BLE

[shipingcong]

Hi All

I mount  a minimum system for test BLE. I download a blinky program to the NRF52810. If I download a blinky without BLE version , it works well . But if I download a blinky with BLE version , It will run to HardFault_Handler . The 32.768KHz clock works well .  How can I fix the problem ?

Thanks

What's the specifications for the 32 MHz crystal you're using?

Fixed , the problem is I use a wrong softdevice .
