Unable to build working firmware

[mh-]

Hi, First of all thanks a lot for publishing this excellent work!

I can successfully flash release v1.6 (sniffle_cc2652rb.out) to my LP-CC2652RB. The red LED blinks, and the python cli tools work as intended.

But when I try to build this binary myself, it doesn't work. I do make clean and make platform=CC2652RB1F load, and the process generates a sniffle.out file, but when I flash that, the red LED stays off and there's no serial output from the board. I tried this on macOS and Ubuntu, using the exact versions of the ARM compiler and the TI SDK that you mentioned, but both sniffle.out files don't work. I also checked out the v1.6 tag in git, to use the same version that you released, but to no avail.

Is there something special you do additionally, in order to create sniffle_cc2652rb.out? Or any idea on how to debug this?

Thanks Michael

Hmm, strange. When I build a release, all I do is run this script: https://github.com/nccgroup/Sniffle/blob/master/fw/build_all_platforms.sh

This is the exact compiler I'm using:

sultan@sultan-neon-vm:~/VMShared/sniffle/fw$ ~/arm_tools/gcc-arm-none-eabi-9-2019-q4-major/bin/arm-none-eabi-gcc --version
arm-none-eabi-gcc (GNU Tools for Arm Embedded Processors 9-2019-q4-major) 9.2.1 20191025 (release) [ARM/arm-9-branch revision 277599]

I suppose you could try diffing the generated .out elf files

Yes, same compiler:

% ~/arm_tools/gcc-arm-none-eabi-9-2019-q4-major/bin/arm-none-eabi-gcc --version

arm-none-eabi-gcc (GNU Tools for Arm Embedded Processors 9-2019-q4-major) 9.2.1 20191025 (release) [ARM/arm-9-branch revision 277599]

Built by me:

% ls -l builds                                                                 
-rwxr-xr-x  1 mh  staff  1802704 Sep 17 19:02 sniffle_cc2652rb.out

Built by you:

% ls -l sniffle_cc2652rb-1.6.out 
-rw-r--r--@ 1 mh  staff  1802496 Sep 16 17:17 sniffle_cc2652rb-1.6.out 

Of course this yields: Binary files sniffle_cc2652rb-1.6.out and builds/sniffle_cc2652rb.out differ

But... It works now (?!?)

Ok... This builds the wrong platform:

% make platform=CC2652RB1F

But this builds the correct PLATFORM:

% make PLATFORM=CC2652RB1F

Sorry, I used lower case letters when I should have used uppercase...
