Flash Layout

The internal flash of the XMC4700 module is organized in a single flash area with 16 sectors. The flash starts at address 0xC000000.

Note

If flash memory must be used in a Zerynth program, it is recommended to begin using it from secure addresses towards the end the bytecode (start address of the bytecode can be found in the log console of Zerynth Studio during the uplink operation), leaving a minimum safe place to minimize the chance of clashes.

Device Summary

  • XMC4700-F144 Microcontroller based on ARM® Cortex®-M4 @ 144MHz, 2MB Flash and 352KB RAM
  • On-Board Debugger

Power

Power to the XMC4700 is supplied via one of the two on-board USB Micro B connectors.

Connect, Register, Virtualize and Program

The Infineon XMC4700 comes with a usb debugger chip on board that allows programming and opening the UART of the module. Drivers are needed (Linux, Mac or Windows) and can be downloaded from the official JLink software page.

Note

For Linux Platform: to allow the access to serial ports the user needs read/write access to the serial device file. Adding the user to the group, that owns this file, gives the required read/write access:

  • Ubuntu distribution –> dialout group
  • Arch Linux distribution –> uucp group

Once connected on a USB port, if drivers have been correctly installed, the XMC4700 device is recognized by Zerynth Studio. The next steps are:

  • Select the XMC4700 on the Device Management Toolbar (disambiguate if necessary);
  • Register the device by clicking the “Z” button from the Zerynth Studio;
  • Create a Virtual Machine for the device by clicking the “Z” button for the second time;
  • Virtualize the device by clicking the “Z” button for the third time.

Note

No user intervention on the device is required for registration and virtualization process

After virtualization, the DevKitC is ready to be programmed and the Zerynth scripts uploaded. Just Select the virtualized device from the “Device Management Toolbar” and click the dedicated “upload” button of Zerynth Studio.

Note

No user intervention on the device is required for the uplink process.
