SPI communication problem with interfaced sensor getting ASSERTION FAILED?

[vishal]

Hello Everyone,

We are using nRF52840 DK with Segger Embedded Studio (SES) using SDK v15.0 We are sending few command to sensor via SPI for reading sensor value. But while reading sensor value getting asseration failed ERROR at line no: nRF5_SDK_15.0.0_a53641a/modules/nrfx/drivers/src/nrfx_uarte.c:269

When I go to this line saw NRFX_ASSERT(p_cb->state == NRFX_DRV_STATE_INITIALIZED); difficult to understand what exactly problem. Please help me for fixing this issue.

Looking forward your response....!!!

Thanks...

Is it?

The problem is that it is not in the INITLIALIZED state - it needs to be!

Hi,

By disabled NRF_LOG_BACKEND_UART_ENABLED 0 in sdk_config.h then this error solved but now getting ERROR 17 [NRF_ERROR_BUSY] at the time of sending command over SPI.

 APP_ERROR_CHECK(nrf_drv_spi_transfer(&spi, address, sizeof(address), m_rx_buf, sizeof(m_rx_buf))); 

Thanks,

Vishal

The NRF_ERROR_BUSY just means that it's currently transferring an SPI transaction, have you just tried to:

while(nrf_drv_spi_transfer(&spi, address, sizeof(address) == NRF_ERROR_BUSY)
  ;

Best regards,

Hi,

I getting one assert ERROR on this below line in nrf_pwr_mgmt.c:

ASSERT((fpscr & 0x07) == 0);

How I can fixed this issue ERROR 3735928559 [Unknown error code] I am using SDK15.0 with segger V4.18 

difficult to find the solution for this issue.

Thanks
