I can’t seem to flash my code the the Spark Core, it just times out.
Seen as I haven’t used it in a long time I thought it might be down to the firmware, so I looked at downloading and flashing via the CLI as the Web route doesn’t work. Although in the GitHub repo dosen’t have any “system” releases https://github.com/particle-iot/firmware/releases.
Unlike Photon and Electron the Core does not have a modular firmware. So you won’t find any system parts as the application binary will also contain the system parts.
So just build for your desired target version, download the binary and flash via particle flash --usb firmware.bin
However Cores tend to suffer from amnesia from time to time, so you may need to reflash the CC3000 too
