I am using Bluenrg-m2sp module and, I have flashed it from serial wire provision. I have used code provided in examples of "BlueNRG-1_2 DK 3.2.1" folder and program name is "BLE_Chat_Master_Slave". In SystemInit() function, code is waiting for the below condition forever:
/* Wait until HS is ready. The slow clock period
* measurement is done automatically each time the
* device enters in active2 state and the HS is ready.
* The interrupt signals that a measurement is done.
*/
while(CKGEN_BLE->CLK32K_IT == 0);
Compile directives used in example:
LS_SOURCE=LS_SOURCE_INTERNAL_RO SMPS_INDUCTOR=SMPS_INDUCTOR_NONE BLE_STACK_CONFIGURATION=BLE_STACK_FULL_CONFIGURATION BLUENRG2_DEVICE HS_SPEED_XTAL=HS_SPEED_XTAL_32MHZ USER_BUTTON=BUTTON_1
I have tried by changing LS_SOURCE to internal 32Khz and XTAL to 16Mhz also. Can someone explain me what is going on in this chip.
