I am considering a design that uses 2 Kinetis processors and having the Master MCU update the firmware on the second MCU via a spare DSPI port.
Usually this would require a custom boot-loader or implementation of JTAG, but the Ezport looks to simplify this task because its SPI.
I'm trying to select a small, low power Kinetis that has Ezport using the Parameter search tool on the Freescale website, but there is no column I can see that indicates whether or not the device is equipped with an EzPort.
Is there a list of devices that have EzPort?
Do any of the MKL ( lower power devices ) have EzPort?
Hello Chad Williams:
All of the parts in the Kinetis K family have EzPort, except for K02, which is an entry level MCU.
As for Kinetis L devices, unfortunately none of them have the EzPort interface.

Hello Chad,
regarding MKL devices, only KL33, KL34 and KL43 seems to include EzPort.
