CC2650: Adaptation ProjectZero to custom board

Part Number: CC2650
Other Parts Discussed in Thread: SYSBIOS

Hello everyone,

Previously I have tested CC2650_LAUNCHXL successfully with ProjectZero.

After this I have made my custom board and flashed it successfully with this project ... But neither Phone discover this device.

I thought maybe I made a mistake with hardware design of the board, but I have rechecked and seems like I did all properly as by Reference Manual.

I have noticed that on CC2650_LAUNCHXL there is 48-pin chip, but on my board 32-pin chips.

Should I change CC2650_LAUNCHXL.h for supporting this chip or it should works as it is ?

Yes, you should revise board pin defines. Maybe you can refer to Using TI Certified Bluetooth ® low energy Module (CC2650MODA) as Single-Chip Wireless MCU which is an application note to porting code to CC2650MODA (5x5 chip embedded).

Man thanks !!

I did as you suggested !!
I have changed:
#define CC2650EM_7ID
to
#define CC2650EM_5XD

But I have faced with that on custom board chip not every time started !!
In assembler I have found that OS got in some exception handler:
ti_sysbios_family_arm_m3_Hwi_excHandler__I():
1001bbc8: 4A05 ldr r2, [pc, #0x14]
1001bbca: B508 push {r3, lr}
1001bbcc: 6812 ldr r2, [r2]
1001bbce: 2301 movs r3, #1
1001bbd0: 8013 strh r3, [r2]
1001bbd2: 4A04 ldr r2, [pc, #0x10]
1001bbd4: 6812 ldr r2, [r2]
$C$L526:
1001bbd6: 2A00 cmp r2, #0 <-----------------------------------------
1001bbd8: D0FD beq $C$L526
1001bbda: 4790 blx r2
1001bbdc: BD08 pop {r3, pc}
1001bbde: 46C0 mov r8, r8
$C$CON596:
1001bbe0: 0148 lsls r0, r1, #5
1001bbe2: 2000 movs r0, #0
$C$CON597:
1001bbe4: 04A0 lsls r0, r4, #0x12
1001bbe6: 0000 movs r0, r0
ti_sysbios_gates_GateHwi_Handle__label__S(), xdc_runtime_System_Module_GateProxy_Handle__label__S():
1001bbe8: B510 push {r4, lr}
...

Maybe you know what could be wrong ? Sometimes chip started successfully. I have tried to guess what is wrong (

I suspect there’s something wrong in your custom HW. I suggest you to refer to and do some checks on your custom board.

I have figure out what was wrong.
I have set as output pin for Red Led:
#define Board_RLED IOID_25

But on my chip I do not have IOID_25 that's why I guess TiRTOS got in some exception or interruption
