New to Zephyr. Can someone kindly help me to toggle LEDs on this simple board? (With schematic, project and board files) Thanks!

Zehpyr is meant to be simple, and the project has few lines of code within boiler-plate files. Hope experienced guys can give me a direction. Thanks.

Official VScode IDE via nRFconnect, and running on the latest SDK 2.5.2.

Can compile and flash, but unsucceful in toggling LEDs as a start.

Simple custom board using the nRF52811 comparable to DK. Here is the schematic, note no DCDC nor 32K.

Project files copied from bluethooth/peripheral_lbs sample, based on which I am experimenting with.

Here is the board files copied from nrf52840dk_nrf52811 board and mofied according to the schematic.

Hi,

You say that your board does not have the 32.768 kHz crystal, but this does not seem to be reflected in your board configs.

Please try to add this to your "silo_2024_01_defconfig file":

CONFIG_CLOCK_CONTROL_NRF_K32SRC_RC=y

The default configuration is to wait for the system clock to become stable before running application code.

Best regards,
Jørgen
