SDK 12.2 require preprocessor symbol NRF52832 or similar to be defined?

[butch]

I am upgrading from v12.0 to 12.2. I am using Linux, Eclipse, GNU ARM and Eclipse managed make.

I get compiler error ...nrfsdk12.2/components/drivers_nrf/hal/nrf_gpio.h:39:2: error: #error "Not supported." Which is related to the symbol GPIO_COUNT which seems to indicate whether the chip has 32 or 48 GPIO pins.

Which leads me to believe I need compiler flag -DNRF52832. Since nrf_gpio.h included nrf_peripherals.h which expects NRF52832 or similar to be defined but it includes nrf.h which only might define NRF52832_XXAA. It seems that formerly, you needed to define NRF52 or NRF51 but now you need also to define a more specific member of the chip family?

Hi,

There seems to be a mismatch in the device check in nrf_peripherals.h (NRF52832) and the backwards compatibility redefine of NRF52 to NRF52832_XXAA in nrf.h.

This issue have been reported internally. For now, you can work around it by defining the symbol NRF52832 as you describe.

Best regards,

Jørgen

I am upgrading from 11.0.0 to 12.2.0 and I'm experiencing the same problem. I define both NRF52 and NRF52832 but still that doesn't fix it.

Are you getting the same error?

I had to define GPIO_COUNT=1 and P0_PIN_NUM=32 too (as I am using a nRF52832 with one GPIO port and 32 pins). I could not test the application as I'm still porting it to the new SDK but that part seems to compile with those defines.

Did you include the path to nrf_peripherals.h and nrf52832_peripherals.h in SDK 12.2? This is included from nrf_gpio.h in SDK 12.2 and is where GPIO_COUNT=1 and P0_PIN_NUM=32 is defined. These symbold will not be defined if these headers is not correctly included in your application.
