nrf_delay_us(999)

[daniel]

Hello,

Just uVision 5.14 and SDK 7.2.0. Try to compile the blinky example and get the next error

._build\nrf51422_xxac.axf: Error: L6218E: Undefined symbol nrf_delay_us (referred from nrf_delay.o).

What's wrong?!

Thank you!!

Hi Daniel,

Have you make sure you referred to nrf_delay.h in the project setting. It's located in \components\drivers_nrf\hal.

The nrf_delay_us function is defined in that file.

@daniel: I'm seeing that you selected the project with s110 but you haven't programmed the softdevice in. So you should either choose the blinky_blank_pca10028 (and don't program softdevice) or use blinky_s110_pca10028 and program the S110 softdevice. The softdevice hex file can be found on our website.
