9.1. P
The microcontroller must enter boot mode for programming, and the programming port must be connected to a
host for program download. To execute the boot transition, and allow programs to download to the microcontroller,
the user must perform the following procedure:
9.2. FDM H
The Renesas FDM (Flash Debug Module) is a USB based programming tool for control and programming of
Renesas microcontrollers, available separately from Renesas. The 3DK serial programming signals PTXD, PRXD,
PSCK and the microcontroller mode pins as well as the microcontroller reset signal are all connected to this
header. The FDM, when connected to the Flash Programming header, is therefore capable of forcing the
microcontroller into boot mode, programming and resetting the 3DK microcontroller.
To utilise this header the user must make the following changes to the board configuration.
1.
9.3. E7, E10A
This device does not currently support any of the E7, E10A or E10T programming tools.
9.4. O
All 3DKs are capable of programming an alternative microcontroller on a secondary board. The user is responsible
for providing this second board containing the alternative microcontroller, its supporting circuitry and an FDM or
FoUSB header for the microcontroller.
To program the alternative microcontroller, the user should perform the following steps
1.
2.
3.
4.
Jumper link J10 must be removed.

-B
Connect a 1:1 serial cable between the host PC and the 3DK board
Depress the RESET switch and keep this held down
Depress the BOOT switch once, and release
Release the RESET switch
Connect a cable between the 3DK programming header and that located on the secondary board.
Slide switch MCU_SEL to the off-board programming position (OFF). This holds the microcontroller on
the 3DK in reset, preventing it from being programmed.
