issues with latest SDK 11.0.0-2

[Richard von Lehe]

I recently grabbed the latest SDK nRF5_SDK_11.0.0-2.alpha. I was looking at some of the changes and wanted to run one or two demos to make sure I was able to build them properly and I could see debug output.

So far I haven't been able to get the hrs_rscs_relay example to run. I've programmed the newer softdevice that was contained in the SDK. I've tried IAR and GCC. Both build without errors. The IAR-generated hex file also programs into flash without errors. When running, I see a single 'R' in the debug output and nothing else. I am using Putty as I did successfully with the older 0.9.2 SDK. I have the correct baud rate.

The GCC-generaed hex file does not program - it compains that part of the image resides in the softdevice area of flash. I haven't made any changes to the IAR project, other than this to get the section placement to work:

Modify line 42 in file “\components\libraries\experimental_section_vars/section_vars.h” as follows: From

#define NRF_SECTION_VARS_REGISTER_SECTION(section_name) NRF_PRAGMA(section = ## #section_name )

to

#define NRF_SECTION_VARS_REGISTER_SECTION(section_name) NRF_PRAGMA(section = #section_name )

I'm not sure why that text became supersized. I'm not using markup.

I'm not sure why the GCC-generated image has some portion outside the application range. I'm attaching the map file for the gcc case. The gcc example is untouched. The only thing I changed was the Makefile.windows to have it point to the correct version of gcc on my machine.

Have others had similar problems?

fs_data_out               0x00000000       0x10  
                          0x00000000                PROVIDE (__start_fs_data, .)
*(fs_data) fs_data        0x00000000       0x10 _build/fds.o 
                          0x00000010                PROVIDE (__stop_fs_data, .)

looks like the problem. That's been placed down at 0x00000000.

Looking at the linker file it has no region (eg > RAM) so I think it would get placed into default which is 0x00000000 and that won't work. I believe the '=0' at the end of it just says it must be zero-filled.

Thanks - yes this fs_data_out section is apparently new this latest SDK. I guess I'll try to figure out where it is supposed to be placed.
