: Hello,
: I have built my own board based on
: 3068F MCU and I have tried to uplod
: a very simple test program to the
: MCU. Unfortunately, the program
: doesn't work as expected. SCI1 TxD
: and RxD are connected through MAX202
: to a DB9 female plug. FWE is
: normally are tied to the GND
: through 10k resistror and MD2 to VCC
: through resistor of the same value.
: In order switch the MCU to the boot
: mode I connect FWE to VCC and MD2 to
: GND through 2x2 pin header and
: jumpers. I'm using FDT 2.2. It seems
: that FDT can connect and upload
: software to the MCU but I don't know
: what should I do next. I simply
: disconnect power supply and jumpers.
: Unfortunately, the software doesn't
: work, but it is almost impossible
: that there is a bug in software. It
: is too simple.
: I would be greateful if somebody
: could send me circuit diagram of
: tested programming interface.
: Especially I am interested in
: handling of FWE and MD2 pins.

: Thanks in advance,
: John
