Configuration of pins at runtime

[NelsonGoncalves]

Hello,

I am writing the device tree for our custom board, which uses an nRF9160 SiP. This approach to configuring the hardware

is new to me, since my experience is with micro-controllers where the hardware is configured at runtime.

With the device trees, once a set of pins is configured for a given functionality (say serial port or SPI) is it possible to change them

at runtime for another functionality ? 

For instance, two pins are configured as Tx and Rx of a serial port, but for testing we would like to be able to at runtime to

change them to I/O pins and control them.

Hi!

Unfortunately, Zephyr does not have a runtime pin control subsystem yet. So if you want to change the device tree during run time, you'll need to use the HAL directly.

Best regards,
