Photon and syncTime

Troubleshooting
21

Thanks. It looks as though the build was not successful since the CRC was not appended to the file.

Please look for any error messages at the end of the build process.

The way to know is to run

xxd user-part.bin

and inspect the last 4 bytes output. If they are 7856 3412 then the CRC has not been correctly written.

Thanks @mdma,

This is the build output from NeatBeans:

BUILD SUCCESSFUL (total time: 6s)

Which shows success, although I can see this, which also suggests CRC:

/usr/bin/sh: /cygdrive/c/Perl/bin/crc32: /usr/bin/perl: bad interpreter: Permission denied

Yep, looks like crc is failing. I see it mentions cygwin in the path - I recommend installing MinGW and using the crc32 from there.

Opened an issue for this here -> https://github.com/spark/firmware/issues/581
