k_sleep() and printk() are not working on nrf54L15 dk

[Archiet]

Hi there,

I am following  nRF Connect SDK Fundamentals and it looks like that both k_sleep() and printk() are not working.

GPIO is working but I am not sure why these two functions do not work.

Regarding printk(), I can see that CONFIG_SERIAL/CONFIG_CONSOL/CONFIG_UART_CONSO are all equal to y. So I assume nothing is needed to configurate.

Regarding k_sleep(), i have no idea what to be checked.

Could you give some hints to me so I could be able to make them work?

Thanks a lot!

Hello,

If you for instance use the solution:
https://github.com/NordicDeveloperAcademy/bt-fund/blob/main/v2.8.x-v2.7.0/l2/l2_e1_sol/src/main.c 

Does it not work as expected? Maybe you are forgetting the K_MSEC() macro inside k_sleep()?

Hi there!

Thanks for reply.

I have tried to add K_MSEC to k_sleep, it is still not working.

Attached files show what I am using, you can find k_sleep and k_msleep in main.c

I am using 2.8 SDK and target board is nrf54115dk/nrf54l15/cpuapp.
