Hi.
We are using nrf52840 with nrf connect 2.7.0.
When compiling my app the DTC complains like so:
-- Generated zephyr.dts: /develop/scms/west_ws/nrf-connect-tondo/app/build/app/zephyr/zephyr.dts -- Generated devicetree_generated.h: /develop/scms/west_ws/nrf-connect-tondo/app/build/app/zephyr/include/generated/devicetree_generated.h -- Including generated dts.cmake file: /develop/scms/west_ws/nrf-connect-tondo/app/build/app/zephyr/dts.cmake /develop/scms/west_ws/nrf-connect-tondo/app/build/app/zephyr/zephyr.dts:58.25-63.5: Warning (unique_unit_address_if_enabled): /soc/clock@40000000: duplicate unit-address (also used in node /soc/power@40000000) /develop/scms/west_ws/nrf-connect-tondo/app/build/app/zephyr/zephyr.dts:350.21-354.5: Warning (unique_unit_address_if_enabled): /soc/acl@4001e000: duplicate unit-address (also used in node /soc/flash-controller@4001e000)
naturally dtc is right as flash controller + acl are sharing space and power + clock are sharing space.
It's a hardware design so i can't do anything about it, also for clock + power some offsets inside the memory space like interrupts are also shared (at least according to the product spec).
So the real question is, is there anything i can do so silence the warnings ? is there a better way to define the device tree so the peripheral is still well defined ? maybe define the base address different to start from the minimal offset that is not shared ?
