DFU programmer through USB

Is it possible anyone can give me some advice on downloading firmware through a USB port to the MCB1800 dev board.

 

My program builds OK and can run when I download firmware through the serial port or when using JTAG, but when I use the DFU programmer through the USB port it downloads OK but my program won't run.

Is there anything anyone can suggest from the screen shots attached.

Thanks

Andrew

Hi Andrew,

Have you considered using LPCScrypt instead?

Hope it helps!

Hi Carlos,

Thanks for that.

I have also tried the LPCScrypt but had no luck.

Using LPCScrypt I can blank check and erase banka OK, i can download the binary file OK but my program won't run.

I know my code is OK because if i use JTAG or download the firmware through the serial port the code runs fine.

When i compare the binary file created with the data from address 0x1a000000 when in debug, they compare the same.

I guess my binary file is wrong but i have used keil in the past to generate binary files and it works OK, i just seem to have a problem with the LPC1857.

Any other suggestions would be appreciated.

Thanks

Andrew
