You need to connect the UART to an RS232 transceiver which is then connected to your PC COM port.
You also need to put the part into ISP mode which requires pulling some pins. See the user manual from NXP for details.

Please email us at support at e s academy dot com for options.

That's a bug in the command line version - no reason to support anything other than 100kb.

No, it's not possible to change it. If we provided an option that doesn't work with the factory bootloader then tech support and frustrated users will increase.

The LED blinking at FM start is a good sign. Did it do that as well as give the "not authorized" error?

Can you please try this:

Install version 11.00.
Open a command window and go to the FM installation folder
Connect the LPC-Link2 with JP1 removed
Run:

  USBManger --list

What happens? What is output? Do you hear any bings/bongs from Windows? Does the LED on the Link2 start flashing?

Thanks, Andy

Close FM
Remove jumper JP1 from the LPC-Link2
Connect the LPC-Link2 to your PC - make sure it is recognized by checking in device manager
Start FM

Currently FM only checks for attached debug hardware on startup.

Do you have three different PCs giving the "not authorized" error?

Thanks for the additional information. Looking at the web server logs and your IP address there is an error message that indicates the connection is being prematurely closed at the client before the server had chance to respond. In this case the result is error code 500 - Internal Server Error, which is misleading. My guess is that a slow connection somewhere along the way was causing your browsers to give up just at the point where the web server was about to send a response.

I just tried Microsoft Edge 41.16299.248.0 on Windows 10 Pro 64-bit version 1709. It downloaded in 10 seconds and opens fine. I then tried it a three more times, clearing the browser cache each time. Always downloaded successfully and takes about 10 seconds.

I then tried Chrome 65.0.3325.181 on the same PC.  Took about 10 seconds, downloaded successfully. I tried it a few more times - always around 10 seconds and always successful.

I then tried Firefox 59.0.2 64-bit on the same PC. Downloads in about 10 seconds, downloads successfully.

We have also tried downloading from UK, USA and Germany - seems to download fine.

I would suspect your internet connection or somewhere between your PC and our server, on the internet perhaps.

I wouldn't recommend it.

I guess an errant Windows update broke something, but perhaps they have now fixed it. Thanks for posting an update.

Yes, you can. Simply avoid erasing after programming the first hex file.

UART/RS232 is point-to-point and isn't designed for multiple devices to be attached to it. Use jumpers or tri-state outputs instead.

Hmmm... downloads seem slow for me as well, but using Chrome the downloads are successful. We will keep monitoring it to see if there is a pattern.

Can you please give me a list of all updates you have on your PC - should be able to see them in Control Panel -> Uninstall Applications. What was installed between the last time it ran OK and March 26th?

Also what service pack level are you at with Windows 7?

Meanwhile version 10.90 is available that does not have this problem.

Thanks, Andy
