nRF Connect SDK example "peripheral_uart" error on nRF52820

[Major Tom]

Hello everyone,

Hello everyone, I am a beginner in programming with OS based systems. I would like to get more into development with the Zephyr based NCS. For now, I want to read out a sensor via I2C and send the values to a smartphone via Nordic UART service.
In my research I came across this article which states that the Nordic UART example corresponds to the peripheral_uart from the NCS:

devzone.nordicsemi.com/.../nus-on-ncs-the-nordic-uart-service-with-the-nrf-connect-sdk

Now I wanted to compile the example for the nRF52820. (Target: nrf52833dk_52820)
However, I get the following error:




Am I getting this right, that the example for the nRF5283 is too big?
Does development with an OS-based system make sense at all for such a chip with little memory as the nRF52820?

Best regards

Hi,

The default configuration use too much memory for the nRF52820 so it will not fit. You can build with the minimal configuration like this:

west build -b nrf52833dk_nrf52820 -- -DCONF_FILE=prj_minimal.conf

Then you will only consume 62 % of the RAM on the nRF52820 (NCS 1.5.1).
