migration of 14.2 FDS app back to 12.3

[paul_tanner]

I have a fairly extensive application built in 12.3.

To add FDS to this I started with 14.2, replaced the logging with RTT and I know I'll have the change the FDS calls.

This builds fine in 14.2 for pca10040 and runs OK.

However, I was not expecting this error when building 12.3:

In file included from ../../../../../../components/boards/boards.h:43:0,
                 from ../../../../../../components/boards/boards.c:40:
../../../../../../components/drivers_nrf/hal/nrf_gpio.h:67:2: error: #error "Not supported."
 #error "Not supported."

This seems to indicate a problem with boards which is odd because pca10040 is supported in bother cases.

Any suggestions please?

Thx.

isn't that error related to GPIO_COUNT not being defined?

 Can't you track the header dependency to see why nrf_gpio.h cannot see nrf_52832_peripherals.h file

Thx @Susheel,

It's because of a parameter called GPIO_COUNT.   This is defined in components/device/nrf52840_peripherals.h

#define GPIO_COUNT 2

The two Makefiles are identical so this evidently has to do with different mechanisms for pulling in GPIO components between the SDKs.

Still at a loss.

The Makefiles are identical and the file structure is identical, and still for some reason nrf_gpio.h cannot see nrf52840_peripherals.h file. If the compiler is also the same, then this will be a mystery difficult to solve. 

Why not brute force add the header into nrf_gpio.h file? You will be able to move on I hope?

Thx Susheel Nuguru

I did try that but just got a world of further errors that are hard to understand.  I wish I had access to whatever tools Nordic have for creating those Makefiles.  The best plan when time allows is probably to start with a correct 12.3 Makefile for another example and try adding FDS to that.

 sounds like a plan.
