System Clock

The JZ-F407VET6 system clock could be driven by an internal or external oscillator, as well as by the main PLL clock. By default, the system clock is driven by the PLL clock at 168 MHz, driven by a 25 MHz high-speed external clock.

Serial Port

The JZ-F407VET6 board has 6 UARTs. The Zephyr console output is assigned to USART1. Default settings are 115200 8N1.

USART1 is accessible via an RS232 transceiver connected to a DB9 connector.

USART2 is configured for RS485 with Modbus support, using PD7 as the driver-enable pin.

Programming and Debugging

The jz_f407vet6 board supports the runners and associated west commands listed below.

	flash	debug	attach	debugserver	rtt	reset
jlink	✅	✅	✅	✅	✅	✅
openocd	✅ (default)	✅ (default)	✅	✅	✅

Applications for the jz_f407vet6 board configuration can be built and flashed in the usual way (see Building an Application and Run an Application for more details).

Flashing

The JZ-F407VET6 board can be flashed using an external ST-LINK/V2 or compatible JTAG programmer connected to the JTAG header.

Alternatively, OpenOCD or JLink can also be used to flash the board using the --runner (or -r) option:

$ west flash --runner openocd
$ west flash --runner jlink

Flashing an application to JZ-F407VET6

Here is an example for the Hello World application.

Run a serial host program to connect with your board via the DB9 RS232 port:

$ minicom -D /dev/ttyUSB0

Build and flash the application:

# From the root of the zephyr repository
west build -b jz_f407vet6 samples/hello_world
west flash

You should see the following message on the console:

$ Hello World! jz_f407vet6/stm32f407xx

Debugging

You can debug an application in the usual way. Here is an example for the Hello World application.

# From the root of the zephyr repository
west build -b jz_f407vet6 samples/hello_world
west debug
