I found that the __FPU_PRESENT in the nrf52820.h caused this problem.The __FPU_PRESENT defaults to 0 in nrf52820.h，The __FPU_PRESENT defaults to 1 in nrf52833.h. The problem is solved after I modified __FPU_PRESENT to 1 in the nrf52820.h.

Hi,

Seems your preprocessor settings miss DEVELOP_IN_NRF52833 and NRFX_COREDEP_DELAY_US_LOOP_CYCLES=3. Please update as

APP_TIMER_V2
APP_TIMER_V2_RTC1_ENABLED
BOARD_PCA10100
BSP_DEFINES_ONLY
CONFIG_GPIO_AS_PINRESET
DEVELOP_IN_NRF52833
FLOAT_ABI_SOFT
INITIALIZE_USER_SECTIONS
NO_VTOR_CONFIG
NRF52820_XXAA
NRFX_COREDEP_DELAY_US_LOOP_CYCLES=3

Are you using SDK 17.1.0? I have modified devzone.nordicsemi.com/.../pca10100e_5F00_radio_5F00_test.zip from pac10010 with the instruction of the "Creating your own emulated project" section. Please place it under nRF5_SDK_17.1.0_ddde560\examples\peripheral\radio_test to run the unmodified radio_test.

Regards,
Amanda
