I am developing a project using nRF5340 to drive some peripherals. During debugging, I found that no matter how I executed the pull-up/pull-down commands, the p1.00 and p1.01 pins remained uncontrollable and always stayed in a high-level state. Why is this? I have attached my config file and overlay file.
Hello,
Try adding this to your nrf5340dk_nrf5340_cpuapp_ns.overlay:
/delete-node/ &gpio_fwd;
I don't have your application to test, but after you do, if it doesn't work as intended, can you please try to run a debug session, and view the GPIO1 registers, particularly the PIN_CNF[0] and [1]. The first bit should be 0 (unlike it is in this screenshot) if the pins are controlled by the application core:
The MCUSEL field should say "AppMCU" if the pin_fwd is successfully disabled.
Best regards,
Edvin

Hi
Thanks for your help. I added the statement you mentioned, but it didn't work. p1.00 and p1.01 still cannot be pulled up or down. Here is the relevant screenshot.
