Andy, thanks for replying, but where is the attach option?  Incidentally, your non-robot verification is rejecting correct answers.  I was asked about the Italian currency, answered "lira" and got the answer rejected.

Click on the reply button (don't use quick reply), then click on "Attachments and other options"

Italy hasn't use the Lira since Feb 28th 2002.

Your post has been approved, so you should be able to reply and attach the file. However first try changing the line feed settings in the advanced options. Try all four combinations.

Looks like you are still running an old version. The version number shown should be 10.67.4823. To double-check I just re-downloaded and installed it and it is correct for me.

Please try version 10.67 and let us know if you still have a problem.

Yes, FM sets the status byte to zero after successful programming. Perhaps age has affected the parts in some way and it takes two attempts to program that location to make it stick?

Probably the best thing to do for the future is to use the command line version so you always explicitly set the status byte after programming.

Please generate a debug file then post back with it attached. Instructions are here:

ARM Cortex / Re: LPC54608 returns invalid device ID
« on: September 11, 2017, 01:19:05 am »
Seems like it might be an engineering sample rather than a production part.

What error do you get when erasing? Have you tried lowering the baudrate?

ARM Cortex / Re: SWD over Link2
« on: August 24, 2017, 08:18:11 pm »
As mentioned via email, the SWD communications are not reliable. Sometimes you are getting a parity error, other times a malformed packet. I would suspect an electrical issue between the LPC4300 on the LPC-Link2 and the target part.

Thanks for posting the solution - it helps users that come after you.

flashmagictool.com, look on the right.

LPC2xxx / Re: Slower baudrates communication (autobaud)
« on: August 04, 2017, 03:15:52 am »
I have no idea why it can't autobaud at higher speeds. Perhaps put a scope on the Tx and Rx pins, send the '?' and see if anything looks strange. Or you could try using the high speed comms mode in Flash Magic.

With a 12MHz crystal you should be able to connect at 38,400 if not 57,600. Something is wrong. If you are using a USB to RS232 cable then try swapping it for a different one. We recommend genuine FTDI cables. Also try a different PC - could be a Windows driver issue.

Some parts require the crystal frequency to know how long erase and programming will take internally. Some parts don't need this. For the LPC2000 you should enter an accurate value.

ARM Cortex / Re: LPC1768 Ethernet Bootloader not work whit EasyWeb

Take the blinky example and start modifying it a bit at a time into what you want. When it stops working you have found the cause.

ARM Cortex / Debugging SWD/USB
« on: July 18, 2017, 01:08:57 am »
This post contains steps to help debug problems with using the "SWD over Link2" and "SWD over LPC11U35" interfaces.

1. I don't have entries in the Interfaces list

For LPCxpresso boards make sure to install the DFU Link jumper and for LPC-Link2 boards make sure to remove jumper JP1. Connect the boards to your PC and make sure they are recognized by Windows in the Device Manager as "LPC device". Then start Flash Magic. At this point an LED on the boards should start flashing.

2. The LED doesn't start flashing

Check the board has been recognized by the PC. In Device Manager look for "HID-compliant vendor-defined device". Right-click and choose properties. Then click on the Events tab and scroll down in the information box. You should see something like "Parent Device: USB\VID_1FC9&PID_F059\xxxxxxxxxx" where xxxxxxxx is the interface serial number.
