K45 Upgrade Files

This is the repository for K45 Upgrade Files. They are compatible with both K1EL K45 Rev A and K45 Rev B versions.

There is a special upgrade application (for Windows) that must be used to update the microcontrollers in the K45. 

Do not use WK3tools for WK firmware updating!!!

Only the main K45 firmware image has been released at this time, there are no updates yet for the K45 WK-IC or the PSOC.

Please do not attempt to upgrade the K45 WinKeyer IC with WK images for WKUSB, WKUSB-AF, or WKmini products they will not work in the K45.

Please take time to read through the Update Instuctions before starting. This is very important, skipping this step is a mistake.
