NRF51 Custom Board - Keil Works but Makefile Does Not

[okan1]

Hello,

I have an NRF51822 custom board. I am trying to flash the code under

C:\Users\Home\Desktop\nrf51\nRF5_SDK_12.3.0_d7731ad\examples\ble_peripheral\ble_app_uart\pca10028\s130

I am trying to flash it with KEIL and it works. I can see NORDIC_UART device on the NRF CONNECT app for Android.

However, if I use the default makefile written already in example file directory:

C:\Users\Home\Desktop\nrf51\nRF5_SDK_12.3.0_d7731ad\examples\ble_peripheral\ble_app_uart\pca10028\s130\armgcc

It does not work. I do not give any error. It prints

Applying system reset

Run

as the last two lines on command line interface (cmd)

I compared the RAM start and size with KEIL settings. Everything is same.

I'm using

make erase

make flash_softdevice

make flash

commands.

I also tried the Makefile with the NRF51 DK, it works with DK.

Is there anything in Makefile or Am I doing something wrong? Please help!

Thanks.

Hi,

Did you change the last line in the makefile, from nrfjprog --eraseall -f nrf52 to nrfjprog --eraseall -f nrf51 ?

How much RAM and Flash do you have on the NRF51822 for the custom board?

You mentioned that you are using the 'default' Makefile from the project folder. In my experience, when my coworkers develop the project in Kiel, and when I bring the same project over to my GCC environment, I have to update all the component folder paths and C file paths before I can run anything. Kiel does not update the Makefile automatically.

So you probably just need to include the missing headers?
