    Hi STARM,

    Thanks a lot for the latest code. I will evaluate it today.

    Is there or will there be a DFU for the STR91x for the Keil Eval board using the ULINK cable? The above .zip file is not intended for this board nor for the ULINK cable.

    Is there IAP example code available on how to program Bank 0 while in Bank 1?

    Hi iamanil,

    Sory for the delay...

    For the DFU you will need at least two GPIO pins beside the USB data lines (D+ and D-).

    The first pin will command the pull up resistor for the D+ line (I suggest you to keep the same schematic used in the STR91x Eval Board)... The second will be used in the selection between the two functional modes (DFU mode and applicative mode) after the MCU reset...

    Regards,

    AnisAS

    Hi:

    We are planning to implement the DFU to our custom board. As I don’t have a copy of the code, I was having problems in understanding its functioning. Do we need to dedicate any pins for the DFU design besides the D+ and D- pins on the ARM9 side? If so, please let me know because this very critical for our design.

    Regards,
