Hi,

when trying to build with example of sdk, I got the following error. it seems to be related with build env setting... please help me to solve it.

Error[Pe020]: identifier "x" is undefined C:\project\nrf52832\nRF5_SDK_17.1.0_ddde560\modules\nrfx\soc\nrfx_coredep.h 161

the code is defined as below.

    __ALIGN(16)

thanks.

Hi,

What example are you trying to build? If it is an example already in the SDK, have you made any changes to it? How are you building the example?

Best regards,

Marte

Hi,

This is related to a bug in the MDK included in nRF5 SDK v17.1.0. There is a note regarding this in the SDK release notes with a workaround:

Note for IAR 8 users:

When using IAR 8, you must apply the following workaround in the MDK:

- Apply a patch to modules/nrfx/mdk/compiler_abstraction.h at line 140
(fix the '__ALIGN()' macro definition): use the argument 'n' in the macro expansion instead of 'x'.

Another option is to download and use the latest MDK version, nRF MDK v8.42.0, where this has been fixed. You can find this by going to the following link: nRF MDK Downloads.

Best regards,

Marte

Hi,

I solved this build issue. when checking root-cause, most errors are caused by the ALIGN(16) usage of nrfx_coredep.h file (161 line). I commented it and also ALIGN(4) usage of nrf_sdh_ble.c file.

thanks for your concern.

thanks.

Hi,

You should not comment out __ALIGN. Please refer to the workaround pasted in my other reply.

Best regards,

Marte
