Hello, i have bought nRF51822 pcb module on Aliexpress (nRF51822 CEAA chip HWID 006A, 16Mhz crystal) and I'm trying to test it with SDK 6.1.0 and S110 v. 7.3.0 (as compatibility matrix recommends for revision 2 chips). It doesn't work. After flashing S110 softdevice and test program (ble_app_hrs example from 6.1.0 SDK compiled on OS X using gcc toolchain), and running it, after few instructions CPU seems to be stuck in some strange loop:
J-Link>loadbin s110_nrf51822_7.3.0_softdevice.hex 0x0

Programs flashed as "blank" (blinky, etc..) work correctly.
Am i making some obivous mistake? What can be the reason of this behavior?
Thanks, Wojtek
