SPI1 Not Reflected in DeviceTree Visual Editor Despite Being Enabled in Overlay (nRF52832 + Zephyr)

[Manav P]

• DeviceTree Visual Editor shows SPI1 as enabled, but the changes are not reflected properly in the GUI or in build behavior.

• I receive the following build error: " DT_N_S_soc_S_gpio_50000000' undeclared here (not in a function); did you mean 'DT_N_S_soc_S_gpio_50000000_ORD? "
  This seems to indicate that &gpio0 or related auto-generated macros are not being resolved, even though I have the node defined or inherited.What is the proper way to fix the 'DT_N_S_soc_S_gpio_50000000' undeclared error ?
  
  Thanks in Advance !

Are you talking about a cosmetic bug in the editor or an actual build error when building the project?

Build error : showing DT_N_S_soc_S_gpio_50000000' undeclared here (not in a function);

You will need to post your changes. Note that there are complete device tree files in build/zephyr subdir.

You usually wanted to start from one of the nordic exampe codes, not the standard zephyr ones: "Create new Application" => "Copy a sample".

Standard Zephyr samples sometimes need prj.cfg or overlay changes to make them work with nordic hardware.

Yes exactly ! I have done the same. Enabled SPI in prj.conf and added SPI1 configuration in overlay. still its throwing this error.

If you could share any reference for establishing SPI bw NRF52832 and a Slave device, it will be really helpful.
