Hi Meghana,

Did you make this work eventually? We are planning to use the same flash chip.

Thanks!

Hello,

Yes I'm referring nRF52832 DK and using same DK to bring up the peripherals with ble_app_uart example code along with nrf_drv_spi(legacy) drivers and also I tried with the spi mode 3. But the issue is same as previous mail that i have already sent you.

I am receiving junk values (some bytes are having proper data and some bytes are junk)

kindly help us to solve the above issue..

As u said in last mail i will check with nrfx_spim driver and will let u know the results of it.

Note: Initially i worked with nRF52810 DK with the software ble_app_uart along with same SPI IC (using nrf_drv_spi legacy drivers) Its working fine.

Regards,

Meghana

Hello Meghana,

[quote user=""]nrf52832 EVK[/quote]

Are you here referring to the nRF52832 DK? I am just asking to avoid making any wrong assumptions.

[quote user=""]Software used : nRF5_SDK_16.0.0_98a08e2\examples\ble_peripheral\ble_app_uart\pca10040\s132\ses[/quote]

By this, I assume you mean that you are working out of the ble_app_uart example, with the addition of the SPI code.
Which SPI example have you used as you reference here?
I would recommend that you make use of the nrfx_spim driver directly, since the nrf_drv_* drivers are legacy.

Could you perform another test where you use SPI mode 3, instead of 0, and let me know what the results are?

Best regards,
Karl
