Hi,
I would like to consult how could I deal with this error and build the code succesfully.
In device.h
'__device_dts_ord_113' undeclared here (not in a function); did you mean '__device_dts_ord_11'?
In devicetree_generated .h
'DT_N_S_soc_S_peripheral_50000000_S_spi_c7000_S_mysensor2_0_P_spi_max_frequency' undeclared here (not in a function); did you mean 'DT_N_S_soc_S_peripheral_50000000_S_spi_4a000_S_mx25r6435f_0_P_spi_max_frequency'?
