Flash and debug using eclipse and GNU

[Tarik]

Hi,

I used the code ble_app_uart_c on board 10028 as a base for my custom board.

My board is nrf51822 QFAA based so I changed all occurances of nrf51422 to nrf51822 and xxac to xxaa on the makefile. I also changed the linker file to the toolchain default "nrf51_xxaa.ld" file. and changed the board definition to my custom board.

The program compiles fine. When I load the .hex file (before loading the softdevie) using NRFStudio the LEDs blink one or two times very fast and then stay ON. If I load the softdevice after that the LEDs never turn ON. And if I load the softdevice before the application I get a message when loading the application telling than I am trying to write a softdevice region.

I made sure to load the s130 softdevice found in "D:\nrf_SDK_12.2.0\components\softdevice\s130\hex\s130_nrf51_2.0.1_softdevice.hex

Trying to debug on eclipse never worked, I have no idea why or how to solve that issue.

If you can please help solve any issue it would be great.

Here is a folder containing documents about all the issues I described:Issue_docs.zip

Thanks

Have you tried to compile without -fno-builtin in your makefile? Don't know which version of armgcc you are using (gcc 4.8.x had a bug), thus I had some issues where I could not use the debugger while this option was enabled. Maybe you give it a try. And I saw that you set D__HEAP_SIZE=0 to 0. Are you sure your program is not using any heap space at all?

I am using the latest gcc (6.2.1), I didn't set any option since I kept everything as it was from SDK 12.2.0 examples. Anyway I tried what you said and it still not working. Thanks

Does you custom board have the 32khz RTC crystal ?

[Tarik]

No my board does not have that crystal

I just changed the softdevice clock to NRF_CLOCK_LFCLKSRC_RC_250_PPM_4000MS_CALIBRATION, but still have the same issues
