element14: Software examples and demos for the LPC4357-EVB

Had a similar issue on Windows 7 x64. Solved with good quality USB cable and correct USB port selection.

The issue was actually in USB port I've been using. Software uses USB device discovery features that requires full USB data cable (no the chap one) and full USB protocol standard support from the controller. So to say, many "front panel" USB 2.0/3.0 ports are also missing full USB support. So I end up connecting my board to the rear USB 1.0/2.0 port (they are usually the first 2-3 ports, where people used to plug mouse and keyboard before). All works like a charm.

I had a very similar issue with Sony camcorder about a year before as well.

I've been working for a month on a board. Hardware is nice and reliable, the board includes almost everything you need to harness the power of LPC4300 system. One this missing is ethernet phy IC.

Be careful of DNP (do not populate, ie missing) components in shematics. There is no second U15 flash chip. Audio input is wired for microphone, not for line in (resistors R29 to R32 need to be reconfigured for line in to function properly).

You can use DFU to upload software via USB (without debugger), but once you write valid image to internal flash, you can no longer use DFU. I added jumper to my board to be able to pull-up P2_7, which enables DFU on reset even with valid image.

The documentation is horrible, best throw it all away and double-check everything yourself. Boot switches are upside-down and reversed, so that table in user manual is just plain wrong. Sample code included on this site is of lowest quality I've ever seen in published software, and parts of it are not even for this board but for Hitex dev kit! Element14 should just remove this code base, it does nothing but waste our precious time.

In my opinion, the best thing to do is to download newest LPCOpen lib and port the HAL layer (board.c and board_sysinit.c) to this board. I've been able to get it up and running on linux with free tools (arm gcc toolchain, openocd, buspirate as jtag adapter, gdb).

For people who are still fighting to get the board to work in the demo out of the box

J2 jumpers:   off, on on on.  

download these drivers:  LPCOpen software platform USBD Library drivers for Windows | www.LPCware.com

(this worked with version 1.2).

modify lpc-ucom-vcom.inf and change all references of the PID 0083 to 2002

Plug in the device, point it to that file.

Open up a terminal session

Buttons 1-5 are the buttons on the board (k1-5), not the your 101 keyboard.

It should print out "You are pressing key0" or the like.

Horrible, horrible documentation and support.  

Hello all, could you help me about wichi flash programming algorithm did you use ?

I tried many options but without good results, I'm using keil mdk with ulink2.

Thanks for any help.

Hey, this is getting very annoying, could you please provide al link at least to the cores ?

Fixing these broken links has been assigned ticket numbers PRE-2019 and PRE-2031.

How to deal with all the broken links after your great UPDATE ?

broken links in "NXP: LPC4357-EVB Development Kit"

How do I get driver, examples etc?  Nearly everything comes up with Broken Link including http://www.element14.com/solutions/http://www.element14.com/community/solutions/8065

Confirmed. Link to examples and demos look like

http://www.element14.com/solutions/http://www.element14.com/community/solutions/8065

for example. Please check the links. Thank you.

Link seems to be broken. I can not download the examples..

Yes, lan Dalziel's methos is valid with Windows XP, but with Windows7 64bit - fail. Driver is  compatible with Windows7 64bit ?
