After set GP0-3, the devce enter DFU mode(got a usb device, vid/pid = 0471/df55)
With 'dfu-util -D /path/to/rom' command, it works fine but not as expected.
As states in user manual Fig18 USB DFU boot mode, if a valid image it received, it will disconnect USB and run the code(no toggle is observed on GPIO2, so I assume it is valid).
But my code seems not running.
With argument -R for dfu-util still not working, and output shows it can't detach(The Device Firmware Update Functioal Descriptor shows CanDowload only in bmAttribute, so it is as expected)
With arguement -a 0 or 1 for dfu-util also not working, and I do not understand the meaning(DFU-UTIL (sourceforge.net))
The code is generated with 'lpc313xImgCreator -pd' which has no prblem
How can I program flash or run code directly on RAM in DFU mode?
Yes, work with normal mode.
Hello,
Can you read the flash, compare value with your image.
Hello,
Have you test your image without DFU mode, just download it with normal mode, does it can work well?
