5 Programming the internal Flash
All Flash devices have an internal bootloader for asynchronous- as well as synchronous-
Flash-programming:
< asynchronous-serial Flash-programming via UART"B"/UART3 (X5)
< synchronous-serial Flash-programming via Serial I/O (SCI3, X17)
5.1 Asynchronous Mode
In order to program the Flash-ROM asynchronously via UART3, the tool "Fujitsu Flash MCU
Programmer for FMC16LX" can be used to flash MB90350 series devices or the tool "Fujitsu
Flash MCU Programmer for FMC16FX" for MB96350 series devices. These tools are
available free on the Fujitsu Micros DVD or Web Site (http://mcu.emea.fujitsu.com/: select <
Development Tools < Software and Utilities)
The following procedure must be followed to enable Flash Programming:
1. Power off the board
2. Connect the Evaluation Board UART"B" to your serial PC communication port.
A straight cable connection has to be used.
3. Check the Jumper-settings according to the UART as described in chapter 4.6
4. Configure the mode:
•
16LX Series
Flash Mode
Async. 4MHz
•
16FX Series
Flash Mode
Async. 4MHz
5. Power on the board
6. Check that the Reset LED is off. Otherwise change the DTR polarity (JP35) and check
the power supply voltage.
