S130 nRF51822 nrf_drv_twi_init softdevice error 0x0001

[Olaf]

I'm using SDK 12.2.0 with softdevice S130 V2.0.1 and want to use TWI. Using the ble_beacon example I added the twi code from twi_sensor. Shortly after calling TWI_Init() the softdevice reports an error SVC Handler Missing.

id=0x0001 pc=0x104AE info=0

iROM is set to 0x1b000 size 0x25000 iRAM is set to 0x20001870 size 0x6790

Preprocessor Symbols: DEBUG __STARTUP_CONFIG BLE_STACK_SUPPORT_REQD NRF51822 BOARD_CUSTOM S130 NRF_SD_BLE_API_VERSION=2 SOFTDEVICE_PRESENT SWI_DISABLE0

define __STARTUP_CONFIG_STACK_SIZE 0x2000

define __STARTUP_CONFIG_HEAP_SIZE 0x2000

Is something wrong with the setup?

I have the same PC and ID being passed to the error handler and I also use a TWI part and am using S130 and an nRF51822. Stumped at the moment, but will let you know if I find anything.

Ran your code on a PCA10028 (nRF 51 DK) and I am not seeing any issues. What does the call stack look like?
