DotExamples build with mbed cli doesn't work

[Rafael Mamro]

Hey guys,

I’m trying to build and run the ota_example from DotExamples project.
The image built with the mbed online compiler seems to work without problems. But when I try to build the project offline with the mbed cli and GCC the built image gets stuck on initialising the mDot when calling:
dot = mDot::getInstance(plan);
throwing the following error on the serial output:
[INFO] Initialize radio…
Timer 0x200059f8 error -3: Resource not available

The toolchains (GCC version 6 and 7) used seems to work, because I’ve already successfully build a couple of projects for other STM32 MCUs.

It would be nice if you could help me to fix the problem.
Thanks in advance!
Rafael

GCC Version 6 should be used
https://os.mbed.com/docs/v5.8/tools/index.html

I use the 2017 q2 release without problem.
gcc-arm-none-eabi-6-2017-q2

Hey Jason,
thanks for your reply!

Indeed, my first attempts were building the example with latest available gcc-arm-none-eabi-7-2017-q4-major. But I already read in this topic that version 6 is recommended. So I also tried to downgrade the toolchain, hoping that this step would solve my problems. I’ve tried all three version 6 toolchains but unfortunately the problem persists.

I’ve uploaded the project and the image binaries to GitHub. Maybe this will help someone to help me 😀

Thanks again and best regards
Rafael

Hey Rafael,

I have the same problem like you under Ubuntu 18.04.
Did you make any progress? Or somebody else?

Hey Dennis,

sorry for my late reply. I was on vacation 😉

Okay I made some progress in this case and can maybe track down the cause a little bit. Now, with current version of the libmdot-dev-mbed5 I can build a release version of the Dot-Examples, that seems to work.
But if I try to build it with:
mbed compile --profile debug -m MTS_MDOT_F411RE -t GCC_ARM
the built image will fail with the same error as mentioned in my first post.

Is it possible, that the precompiled libraries have no debugging symbols and that’s why it is failing for some reason?

Regards
Rafael
