I am trying to flash a LPCXpresso LPC1769 with command line utilities on Mac OS X.
System : Mac OS X 10.7.5
LPCXpresso version 7.1.1

The command list I have tried in a shell script is :

cd /Applications/lpcxpresso_7.1.1_125/lpcxpresso/bin &&
./dfu-util -d 0x471:0xdf55 -c 0 -t 2048 -R -D LPCXpressoWIN.enc &&
./crt_emu_cm3_nxp -info-target -wire=winusb &&
./crt_emu_cm3_nxp -g -4 -wire=winusb -plpc1769 -flash-load-exec=/my-path/product-internal-flash.elf

Execution freezes invoking info target :

+ cd /Applications/lpcxpresso_7.1.1_125/lpcxpresso/bin
+ ./dfu-util -d 0x471:0xdf55 -c 0 -t 2048 -R -D LPCXpressoWIN.enc

What I am doing wrong ?

The IDE will DFU the probe if it recognizes an enumerated device with a VID/PID associated with a supported DFU device. Otherwise, it won't be used.

Ok, the first time I do :

./dfu-util -d 0x471:0xdf55 -c 0 -t 2048 -R -D LPCXpressoWIN.enc &&
sleep 2 &&
./crt_emu_cm3_nxp -flash-load-exec "/mypath/product-internal-flash.elf" -g -2 -vendor=NXP -pLPC1769  -wire=winUSB -s250  -flash-driver=LPC175x_6x_512.cfx

And the next times :

./crt_emu_cm3_nxp -flash-load-exec "/mypath/product-internal-flash.elf" -g -2 -vendor=NXP -pLPC1769  -wire=winUSB -s250  -flash-driver=LPC175x_6x_512.cfx

This perfectly runs. Thanks !

Strangely, the IDE always uses dfu-util, so I have to unplug the board before every flashing. Is there an option to avoid this ?

It will fail as you should only boot ( use dfu-util ) once until you next power cycle the board.

After booting you have to allow time for th OS to re enumerate the device on usb

I have found what was going wrong.

The correct sequence is:

cd /Applications/lpcxpresso_7.1.1_125/lpcxpresso/bin &&
./dfu-util -d 0x471:0xdf55 -c 0 -t 2048 -R -D LPCXpressoWIN.enc &&
sleep 2 &&
./crt_emu_cm3_nxp -flash-load-exec "/mypath/zPRODUCTS/product-internal-flash.elf" -g -2 -vendor=NXP -pLPC1769  -wire=winUSB -s250  -flash-driver=LPC175x_6x_512.cfx

My interpretation is the -R option of dfu-util invocation performs is reset, and LPC-Link needs time to reset. Adding a 2-second wait solves the problem.

However, invoking the script again always fails : I always need to unplug the LPCXpresso board in order to flash again.

Thanks for your response

Yes, I do not use the keyboard USB port. I have seen this message on the forum :
http://www.lpcware.com/content/forum/lpcxpresso-ide-not-able-establish-lpc-link-lpcxpresso-812

I have the same behavior for every high-powered USB port.

Have you tried different USB ports?

Ok, I have found the "program Flash" button.

First, it tries to connect to to Redlink Server, fails, displays 2 error sheets, and the same with CMSIS-DAP, ...

Finally it displays the progression window: "Initializing LPC-link v1.1 with LPCXpressoWIN.enc".

Then a dialog appears, I have got the command line that is used by the IDE :

crt_emu_cm3_nxp -flash-load-exec "/myPath/product-internal-flash.elf" -g -2 -vendor=NXP -pLPC1769  -wire=winUSB -s250  -flash-driver=LPC175x_6x_512.cfx

So my script becomes :

cd /Applications/lpcxpresso_7.1.1_125/lpcxpresso/bin &&
./dfu-util -d 0x471:0xdf55 -c 0 -t 2048 -R -D LPCXpressoWIN.enc &&
./crt_emu_cm3_nxp -flash-load-exec "/mypath/zPRODUCTS/product-internal-flash.elf" -g -2 -vendor=NXP -pLPC1769  -wire=winUSB -s250  -flash-driver=LPC175x_6x_512.cfx

Bit it still fails:

+ cd /Applications/lpcxpresso_7.1.1_125/lpcxpresso/bin
+ ./dfu-util -d 0x471:0xdf55 -c 0 -t 2048 -R -D LPCXpressoWIN.enc

How can I get the code invoked during "Initializing LPC-link v1.1 with LPCXpressoWIN.enc" progress windows ?
Is my command "./dfu-util -d 0x471:0xdf55 -c 0 -t 2048 -R -D LPCXpressoWIN.enc" valid ?

If you use the Flash Utility (from the toolbar), the command line is displayed.

It works sometimes with the GUI. I need to unplug and replug the LPCXpresso board when I launch again.

How the invoked command lines can be displayed ? I have taken a look on all preferences, project settings, and find nothing.

Does it work through the GUI? If so, look at the command line that issues, and use that...
