Firmware

I have uploaded the instructions to Google Docs. I think I captured everything here, if I missed something let me know and I will edit the file and make the corrections.

Eclipse IDE with Programmer Shield

Thanks! Iā€™ll take a look and include your instructions into the docs.

I appreciate your comment on the manufacturing. I passed it on to the rest of the team.

Hi, I am working through your guide (only difference is I am on Mac, not Linux, and I had to add PATH with usr/local/bin/ before build would work). I am to the part of configuring the external tool in Eclipse, and I canā€™t find firmware/build/target/main/platform-6 on my system. I can go as far as firmware/build/target. There is no main directory. Any idea why it isnā€™t there?

24

Also, Looking at the logs, Eclipse is use the make that comes with Xcode, not the one I installed at /usr/bin. Do you know how to change Eclipse to use that make?

25

Okay, it turned out to be a permission problem. I thought the build command worked, but it couldnā€™t make a directory and quit. Changed that and now the main folder is there.

26

Sounds like you are making progress. I included a link to the setup to compile and load using a MAC, make sure that works first before moving on the making the debugger work.

Thanks. I think I am getting closer to getting it working. I am now getting an error with the dfu-utilā€¦ dfu-util: Last page at 0x08105b6b is not writeable

dfu-util: Invalid DFU suffix signature
dfu-util: A valid DFU suffix will be required in a future dfu-util release!!!

I had the DFU-Util working earlier in the guide, when we make and then program-dfu from the command line. The weird thing is, I got this error, and then took a break for dinner, and came back and the photon is breathing cyan, like it did get flashed.

Question: In setting up OpenOCD in Eclipse, How do you get firmware/build/target/main/platform-6/main.elf to show up. I can have firmware/build/target/ There is no main directory.
Thanks

Okay, Once again permission issue crept up.

Glad you found it
