CMake Error at C:/ncs/v2.9.0/zephyr/cmake/modules/boards.cmake:196 (message): Error finding board: nrf52833dk

Hi guys, I am using the SDK v2.9.0 and the toolchains b620d30767. To add the build configuration for the sample peripheral_uart, the console print some error log.The log as below:

Could you help me to fix it? thank you!

Strange. I have no experience developing using Visual Studio Code or Windows unfortunately. But with the same version of the toolchain on Linux, I get another, very unrelated, error when building using the command line:

$ west build --build-dir build/peripheral_uart --board nrf52833dk/nrf52820 nrf/samples/bluetooth/peripheral_uart

[...]

/home/jakob/ncs/toolchains/b77d8c1312/opt/zephyr-sdk/arm-zephyr-eabi/bin/../lib/gcc/arm-zephyr-eabi/12.2.0/../../../../arm-zephyr-eabi/bin/ld.bfd: zephyr/zephyr_pre0.elf section `noinit' will not fit in region `RAM'
/home/jakob/ncs/toolchains/b77d8c1312/opt/zephyr-sdk/arm-zephyr-eabi/bin/../lib/gcc/arm-zephyr-eabi/12.2.0/../../../../arm-zephyr-eabi/bin/ld.bfd: region `RAM' overflowed by 1348 bytes
collect2: error: ld returned 1 exit status
ninja: build stopped: subcommand failed.

So it seems like the MCU does not have enough RAM for this sample application. The same sample works for example when I build it for the board `nrf52840dk/nrf52840`, like so:

$ west build --build-dir build/peripheral_uart_nrf52840 --board nrf52840dk/nrf52840 nrf/samples/bluetooth/peripheral_uart

However. That is probably very unrelated to what you are experiencing.

Some things to test:

- Can you build that example for another board?

- Can you build another sample applications for that board or another?

- Is it possible that some file in your SDK/toolchain has been accidentally modified or corrupted?

Thank you sir, maybe there are something wrong with the nRF Connect SDK which i got. I got the SDK from another way and everything is well. Have a nice day!

Great to hear that! Please consider to mark this question as solved. Good luck with your project!
