LPCOpen USB example errors

Hi.

I've been getting up and running with LPCXpresso (v5.0.12) and the LPC4357 using the mcb4357 evaluation board, LPC-Link programmer and LPCOpen platform.

Unfortunately i always get this error: "15: Target error from Commit Flash write" when trying to debug any of the single core USB examples. The basic blinky examples (both single core and dual core) work perfectly, however I can't get any of the usb examples to work.

The dual core usb mass storage example programs and starts the debug session fine but then always jumps immediatley into a hardfault so I can't get anywhere with that either.

I've read through the other posts and wiki entries on this error and have tried using an external 2A power supply, enabling vector catch and booting into the ISP bootloader. None of these has made any difference.

When attempting to program the board using the keyboard example and the flash tool i get a similar error and the following log:

I'd be very grateful for any help as I need to get this working asap as we need to decide on a new microcontroller platform for our new product range.

I've just downloaded and installed LPCXpresso v4.3 and most of the examples now seem to work. I've tested all the applicable single core examples and they are fine. The dual core blinky works too. The only one that doesn't work is the dual core mass storage example, which gives a usb device fault in windows.

It seems that version 5 of LPCXpresso breaks the LPCUSBlib examples. Is this also true of the code red suite? If it is then I would be very reluctant to fork out the cash to invest in this platform. If this problem isn't isolated to myself, it also shows that version 5 wasn't fully tested before release, which is another worrying sign.

I plan on getting an evaluation copy of Red Suite 5 to see if these problems persist. Let me know if you have any more information on the matter.

Hi,

I'm still not having any luck on this, any suggestions? If I can't get this working soon, we'll have to move over to a different platform, which would be a shame as this processor looks like the best solution.

sorry, I changed the optimisation options between making those two posts in the hope that it might make it work.

Here is the map, log and axf. all from the same build.

I think that we are going to need to see the actual generated AXF as well please.

Also, I suspect that the map file that you provided does not match with the actual build used for the debug log file that you originally provided?

Thus could you please provide matching map file, axf and debug log?

since updating to the latest version, I still get the same error "15: Target error from Commit Flash write" when debugging the usb keyboard example, however when closing the message box, the debug window stays open and I can now pause and resume the program. I also get a USB Device not recognised error in windows.

For all the other examples, the behaviour is the same as i described in my original post. I've attached the .map file for the keyboard example.

Please try again with LPCXpresso 5.0.14, which was released yesterday.

If that doesn't help, then please can you attach the map file generated by the linker when you build your application.
