Configuring the HDK flash mode
The MT7682 HDK is embedded with 1MB flash memory. The boot options are either from the Flash memory or
from the UART port.
To update the firmware on the MT7682 HDK:
1)
Set the jumpers
J2002
pin 1 and pin2,
J2003
pin 1 and pin2,
J2004
and
J2007
on.
2)
To enable the chipset to UART download mode, set the jumper
J2201
pin 2 and pin 3 on.
•
In this mode, if the power is on, the board will load ROM code and start the
ATE Daemon
or
Firmware
Upgrade Daemon
according to the MT7682 Flash Tool’s behavior on the PC. A message is sent to the
UART0
port of the chipset and the code is uploaded to the embedded flash memory through
UART0
.
3)
Connect the board to the computer using a micro-USB cable.
The development board should now be connected to the PC, as shown in Figure 2.
To run the project on the MT7682 HDK:
1)
Set the jumpers
J2002
pin 1 and pin 2,
J2003
pin 1 and pin 2,
J2004
and
J2007
on.
2)
Remove J2201 jumper, to set the board into a flash mode.
•
In this mode, if the power is on, the board will load firmware from the Flash and reboot.
3)
Connect the board to a computer using a micro-USB cable.
