Hi,

May be ( ? ) some interesting links here :

You need to ground one pin before power up.

If you have all of the power pins connected and pin 10 (CTS) connected to ground the LEDs should blink when ever a memory stick is plugged in.

If the stick has a file named
FTRFB.FTD
in the root directory, the VDIP module will start the flash process from there.

VDIP1 is really driving me crazy. Thanks for all the help. Hope it works.

By the way, do we have to do something to the jumper setting for reflashing the VDIP1? Which mode of jumper should we use?

How do we know that the Firmware has been loaded in successfully? The 2 LED's of VDIP1 flashes alternately on powering ON. When flash disk is plugged in, 1st LED ON and 2nd LED OFF for under 1 sec. After that, the state of the 2 LED's change and lastly, the LED state became stable (only LED1 is ON). Does this mean the FW has been loaded in (VDIP1 reflashed)?? The process happened in just few seconds, is this ok?

If you are using serial mode then the two sets of jumpers with three pins should be jumped across 1 and 2 or 2 and 3. It does not matter as long as both are the same.

How do we know that the Firmware has been loaded in successfully?

The easy way I think is to connect pin 6 through a level shifter (max232) and monitor the VDIP on a terminal. It does not take long to update/change the firmware, small file.

For that matter , use a terminal to learn how the VDIP works, practice sending commands and reading the feed back.

We are trying to design a product to transfer data using FIFO mode. The problem now is it doesn't show any respond like when we connect it using UART mode. The LED's just ON alternately for 2 seconds only indicating power on. But, when a flash disk is plugged in, nothing happens. What seems to be the problem?
Should ground all the address lines? Any other hardware config?

By the way, can MCU 8051 be used as a monitor for VDIP1? Is it compatible with VDIP1? Or maybe any other suggestion for the monitor?

Thanks.
