Porting application to nRF52810

[Alan Ajit]

Dear nordic,

I have application that developed using development kit pca10040 . I want to change it to supporting nRF52810. i follow the instruction the link :-

http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.sdk5.v15.0.0%2Fnrf52810_user_guide.html&cp=4_0_0_5_0:

but its little bit confusing. MY ide is keil 

1. Open the example project for your IDE.
2. In the project settings, change to device "NordicSemiconductor->nRF52810_xxaa".
3. In the C/C++ preprocessor settings, remove the defines "NRF52" and "NRF52832_XXAA".
4. Add the preprocessor define "NRF52810_XXAA".
5. In the linker script settings, adjust the linker script to match the maximum RAM and flash size of nRF52810.
   • ROM END: 0x2FFFF
   • RAM END: 0x20005FFF
6. Remove the following files from the project: <compiler>_startup_nrf52.s and system_nrf52.c.
7. Add the following files to the project: <compiler>_startup_nrf52810.s and system_nrf52810.c.

i changed the  device to 810 .

In  3rd step preprosessor :-

where i change that

in 5 th step where i change the size of ROM and RAM

and also in last steps where i change that files . need some support

Thanks for your replay.

I set my application as per above and build it . It show some error:-

can you help me to solve this ?

and i have one more doubt in porting. In 3 rd  and 4th step says:- In the C/C++ preprocessor settings, remove the defines "NRF52" and "NRF52832_XXAA". 

where i change this?

my ram and rom settings like below:-

Is it right?

[Alan Ajit]

Thanks again. now the problem when i build the program it's show error:-

why show this error?

RTE\Device\nRF52810_xxAA\system_nrf52810.c(169): error:  #136: struct "<unnamed>" has no field "MAXPACKETSIZE"

I need some support

[haakonsh]

Hmm, that's wierd. 

What are your C preprocessor flags?

[Alan Ajit]

when i check in c preprocessor in target option --->c/c++

define contain:-

BOARD_PCA10040 CONFIG_GPIO_AS_PINRESET FLOAT_ABI_HARD NRF52 NRF52832_XXAA NRF52_PAN_74 NRF_SD_BLE_API_VERSION=6 S132 SOFTDEVICE_PRESENT SWI_DISABLE0 __HEAP_SIZE=0 __STACK_SIZE=8192

 Is it right?

Is it  any changes needed?

[haakonsh]

From the guide: 

3. In the C/C++ preprocessor settings, remove the defines "NRF52" and "NRF52832_XXAA".

4. Add the preprocessor define "NRF52810_XXAA".

[Alan Ajit]

I change the c/c++ preprocessor like below:-

BOARD_PCA10040 CONFIG_GPIO_AS_PINRESET FLOAT_ABI_HARD NRF52810_XXAA NRF52_PAN_74 NRF_SD_BLE_API_VERSION=6 S132 SOFTDEVICE_PRESENT SWI_DISABLE0 __HEAP_SIZE=0 __STACK_SIZE=8192

Is it right?

But till i get error

RTE\Device\nRF52810_xxAA\system_nrf52810.c(169): error:  #136: struct "<unnamed>" has no field "MAXPACKETSIZE"

what changes are i do to resolve this error?

[haakonsh]

What happens if you set compiler optimization to lvl 0?

[Alan Ajit]

No change same error again 

[haakonsh]

The error is due to the compiler using nrf52.h instead of nrf52810.h 

Most likely NRF52 is defined somewhere in your project, though any source file that includes nrf52.h will be at fault.
