How to create a Makefile based project?

[swetha Paladugu]

Hi,

I am new to creating project from scratch.

I want to use nRF51802 module. From few support tickets i have come to know that  SDK version 12.3 and SoftDevice S130 version 2.0.x  are the compatible versions for nRF51802 module. Are these the latest combination for nRF51802? What should i use?

And i want to create a project which is IDE independent project, a Makefile project.

Can anyone please guide me how to create a makefile project for nRF51802 module?

Thanks,

Swetha.

Hi Edvan,

I have used the makefile from "\examples\peripheral\blinky\pca10028\s130\armgcc" this path and in. ld file we have changed to the memory sizes as you mentioned.

RAM (rwx) :  ORIGIN = 0x20001fe8, LENGTH = 0x2018.

But device is not booting after flashing. we have also flashed softdevice at the beginning.

But If i am directly flash the hex file from this path "\nRF5SDK1230\nRF5_SDK_12.3.0_d7731ad\examples\peripheral\blinky\hex\blinky._pca10028.hex", device is booting and blinking.

So, we are assuming that either the memory addresses that are mentioned in .ld file have some issue or the defines and cflags that are set in makefile have some issue.

The compiled hex file is of size 10kb and the actual hex file in this "\nRF5SDK1230\nRF5_SDK_12.3.0_d7731ad\examples\peripheral\blinky\hex\blinky._pca10028.hex" path is 7.25kb. These 2 file sizes should actually be same, but we could see the difference. 

Can you please help in setting up?

Thanks,

Swetha.

Hello Swetha,

Have you flashed the softdevice separately?

 Did you compile this using an armgcc compiler, or is this after you ported it to SES?

What SDK are you using? Where did you find the RAM settings? And what are your flash settings? In SDK12.3.0, the settings are:

  FLASH (rx) : ORIGIN = 0x1b000, LENGTH = 0x25000
  RAM (rwx) :  ORIGIN = 0x200013c8, LENGTH = 0x6c38

Perhaps you can try these settings.

Does the LEDs blink if you test the pca10028\blank\armgcc makefile? This file doesn't require a softdevice. 

BR,

Edvin

Edvan,

I would need help in creating bootloader dfu project and the necessary changes to be done in application for nrf51802 module.

That sounds like a topic for a new ticket. But I think you should wait with your bootloader until you have an IDE that you know for certain is working properly. If not, I don't know if your issues are caused because of your IDE or your bootloader.
