I'm using Ubuntu 14.04.3 x86_64 development platform and installed LPCXpresso v7.6.2. I tried to flash new programs to LPCXpresso LPC1769 target from the IDE, which progressed in the download for long time and didn't complete. So I planned to use the command line utils to flash the target.

$ cd /usr/local/lpcxpresso_7.6.2_326/lpcxpresso
$ bin/dfu-util -d 0x0471:0xdf55 -c 0 -t 2048 -R -D bin/LPCXpressoWIN.enc

And the program was waiting at the writing step for a long time w/o any progress. Am I missing any step here to successfuly flash the target image?

What happens if you debug the application?

The program got downloaded successfully and debug session started when I 'Debug the application'!!
I'm planning to run eLua on the LPCXpresso LPC1769 target, so expecting to download the binaries with few simple commands. So 'Debug' is a way to download the application to target flash usually?

'Debug' is used to Debug :D

If you want to flash, use 'Program Flash':

or command line flash programming tool:

The command line flash link helps!
I ran the dfu-util command once for the first time when the target is USB plugged-in and then ran flash_utility as many times to download different applications.
Thanks R2D2 :exmark:
