can you push this project to github ? it will be very, very useful to a lot of people.

Only an idea : try to extract only sections from hex.

objcopy -Iihex -Obinary --only-section .sec1 $Build.hex $Build.bin

if section is not right try with .sec2 or .sec3.

Thanks, it is good to know. There is however one little problem I haven't figured it out. Don't know if you can find out. When generating a .bin file, the size is over 2MB due to the relocation. How can it be strip down to normal size. The .bin conversion is done by adding this line

arm-none-eabi-objcopy -O binary ${BuildArtifactFileName} ${BuildArtifactFileBaseName}.bin;

C99 __asm vs gnu99 asm.

I've made a test and is possible to use both (C99 and gnu99) setting :

Set with gnu99 --> asm with C99 --> __asm

the compiled file are the same in text, data, bss, dec and hex sizes.

Nguyen Hoan Hoang — Sat, 17 May 2014 06:32:36 GMT

An other thing I forgot. StartupnRF51.c works with C++. gcc_startup_nrf51.S does not.

RE: Eclipse GCC pure project for DFU Bootloader nRF51

Nguyen Hoan Hoang — Sat, 17 May 2014 06:19:31 GMT

I forgot your question about using the gcc_startup_nrf51.S. Yes you can use it. You will need to use the linker script from the SDK too. I made few changes in the linker script for my startup code.

RE: Eclipse GCC pure project for DFU Bootloader nRF51

Nguyen Hoan Hoang — Sat, 17 May 2014 06:14:49 GMT

The compiler_abstraction.h is not my code. It's the SDK and there is an error in that file. Then inline assembly in GNU compile is __asm(...) not asm(...). You need to change it.

The StartupnRF51.c is not a translation of the .s file. It was ported form my other ARM processor. I write multi-platform code. It does not depend on the SDK. It is generic for GNU compiler and ARM processors. Now a day writing code in assembly is only for special optimization. Otherwise not recommended. It is a maintenance nightmare.

The dfu code is still all Nordic code. I only make few changes to make it compiles with GNU. mainly asm stuff. So yes App needs to start at 0x14000. No change to that.

RE: Eclipse GCC pure project for DFU Bootloader nRF51

cocoa — Sat, 17 May 2014 04:44:38 GMT

C99 or gnu99 ?

Hi Nguyen, there in a strange behavior in your code, infact, if i compile with -std=gnu99 all goes ok but if I set -std=C99 (your preferred choice and , as you said, needed by SDK to be compiled) these errors was raised :


/nrf51_sdk/nrf51822/Include/compiler_abstraction.h:73:30: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'asm'

/nrf51_sdk/nrf51822/Include/compiler_abstraction.h:73:30: warning: implicit declaration of function 'asm' [-Wimplicit-function-declaration]

/nrf51822/Include/compiler_abstraction.h:74:16: error: 'sp' undeclared (first use in this function)

/nrf51822/Include/compiler_abstraction.h:74:16: error: 'sp' undeclared (first use in this function)

More interesting is the fact you do not use the asm file gcc_startup_nrf51.S but a translation from asm to c file StartupnRF51.c .

Can you tell me more about ? Is it possible to compile using using the original asm file or changes are needed ?

Does this file be compatible with all SDK (old and news) or must be rewritten ad hoc for every SDK?

If I would compile hrf example to be used with boot loader generated from you eclipse project I need to change specific address memory flashing with jlinkexe (os x version) or the firmware starts at the same address (0x014000) ?

Thanks.

You only need to set the include path to the location of pstorage_platform.h

RE: Eclipse GCC pure project for DFU Bootloader nRF51

Nguyen Hoan Hoang — Fri, 16 May 2014 17:12:56 GMT

Yes, I did change it. It is set with the project settings. The SDK require C99 to compile. It is also my preferred settings.

Hi, I remember a similar issue, have you changed language standard from -std =C99 to -std=gnu99 ? You can do it in Settings.

you should have these include path set like this for the SDK

and the missing header files is in app_common directory, under .nrf51822/Include.

I'm not sure what am I missing?

RE: Eclipse GCC pure project for DFU Bootloader nRF51

you need to change the include path for the SDK to the location where you put it. I put the Nordic SDK nrf51822 in nrf51_sdk. When compiler complains about a .h file, check for the include path of the C & C++ settings.

The bootloader needs to be compiled with optimization for space. Compile in debug by default has no optimization. Try to compile it in release mode.
