How to Using the Demo

Those demos projects present how to upgrade mXTouch firmware through a Host platform. For using those projects, there at least need an MCU host board, Both SAM D21 Xplained Pro Evaluation Kit and SAMA5D27-SOM1-EK1 can be used as Bootloader Host Platform.

Convert MaxTouch firmware and configuration file to binary file

Before running the demo, the maXTouch firmware needs to be converted to the binary file, following bellow command to convert a ENC file to the binary file.

xxd -r -p mXT1067TDAT_0x3D_1.0.00_PROD.enc > mXT1067TDAT_0x3D_1.0.00_PROD.bin
