Can you connect to the bootloader using Hyperterminal when using the internal oscillator?

Hi Andy
I am able to connect to Hyperterminal with internal crystal when the code is downloaded via JTAG or flash magic with external crystal( crystal is removed after downloading the code) . I am not able to download a code without external crystal.
Thanks in Advance.
Regards
Sandeep.

Yes, but are you able to autobaud with the bootloader using Hyperterminal when using the internal oscillator? The test I am suggesting has nothing to do with JTAG.
Note that there isn't an internal crystal, just a resistor-capacitor based oscillator.
If Hyperterminal can connect what is the Flash Magic error message?

So the Flash Magic terminal works but the rest of the Flash Magic GUI does not? Please generate a debug file showing your attempt to use the GUI. Instructions are here: http://www.flashmagictoo.com/autobaud.htmlThen send the file to me. Andy |

Hi Andy
Now I am able to download the code with Flash Magic GUI also after Flash magic Terminal communication established fine.
Thank you.

Hi
1). Make sure that Hyperterminal is communicating properly with Internal Oscillator before programming in flash magic GUI.
2). If autobaud error occurs while downloading the hex code, try to communicate with terminal in flash magic (Tools->Terminal) if this communication established fine as same Hyperterminal then close (while closing if flash magic doesn't respond properly then kill that process in windows task manager) and reopen flash magic, now hex code can be downloaded easily with Flash magic GUI without external crystal.
Regards
Sandeep.

I think something is not quite right with your setup. If you want to investigate this further the first thing to try would be another PC. If the one you are using does not have a COM port then try one with a built in COM port.

Hi Andy,
I am having a similar problem and had to use the same remedy, the terminal interface. I still got some communications errors but it was able to re-program OK. The link to log the info for debug was broken, can you send the correct one so I can see what is going on? (and to send a copy to you.) Also, FYI, prior to this I was able to program using SWD. After loading a program, the SWD no longer worked. And, when I tried Flash Magic, I had a autobaud error. So, I think there is something going on with the LPC1114. After erasing, I was able to re-program with SWD. The only thing I can think of (other than a problem with the device) was the CRP3 got set accidently, which is why I want to check the communications log. FYI, I am using Keil tools. Any suggestions you have would be welcome.
Regards, Jim E.

OK, firstly did you set the CRP value? You need to do this in your project. Your Keil startup file might have this in already and set it to zero. You can also double-check this by looking at the hex file. It should be easy to find the values be programmed at the CRP location. The instructions for generating a debug file are here: http://forum.flashmagictool.com/index.php?topic=3272.0 |
