I found the solution! That may be the problem – I’ve seen mention of various issues whne VBat has no voltage on it.

Thanks for any help. Thanks in advance for any idea. The subsequent power stages 5V and 3. I have probably checked for every possible pin that could send the LPC into some other mode and prevent it from responding to ISP.

I tried many times and always failed.

This may sound too simplistic, but I have faced this number of times my self Regards, Prerak On Thu, Aug 20, at I don’t now the reason for this. Yes originally the method I quoted earlier worked for me. Products Download Events Support Videos.

The can be programmed by ISP and can run program when power on. Voltages on datashete power pins are OK. This site uses cookies to store information on your computer.

I checked all the pin usage again, and found that I am using pin P1. I scoped the serial port signals and traced with a serial port monitor.

Errata documents do not mention anything relevant to this problem. Hello, I further rechecked the schematic and the tested the boards again. If it is pulled up and you are not grounding to program, then it would never recognize programming mode.

Is there any issue or a trick to get the LPC working, or could it be plain dead The voltages at all power pins are ok. There was a issue with the power supply circuit in the begining, the first stage 15V switching regulator catch diode was connected in reverse bad footprint used by the PCB designerand I had to replace the regulator.

Arduino Robotics Lonnie Honeycutt.

Can a reversed catch diode of a switching regulator inflict such damage on rest of the circuit? Sorry I did not explain the complete situation. However after I changed them back, the error was still there. But, if somehow the 5V rail could have been affected, it could have damaged the P0. But why do I get this error in the first place? Introduction to Microcontrollers Mike Silva. I just received the assembled PCBs and I tried to put in a test program. I also tried resetting the controller by shorting the reset capacitor, after power up.

Could not stop ARM device?

Only RCLK has nothing happen. Posted by “Charles R. Now for the same circuit, one board has this problem and another one can work well with jtag.

The host keeps sending 0x3F ‘? It looks hard to replace a LPC and I am wondering from where can I buy and get it quickly in canada? I don’t know the problem you are having, but to assist, you can bring up a terminal session on the ISP port and type?????

Could not stop ARM device?

Rest of the microcontroller may well be ok, but there is no way it can respond to ISP requests now. I had the same problem when i got some new ‘s with them all and my old one’s, based upon worked fine. This pin dagasheet low at startup, makes pins P1. I think I know what can be the problem. Please review our Privacy Policy to learn more about our collection, use and transfers of your data. JTAG clock to kHz and it works.

Apparently, this trace port affects functions of only certain pins of course, that is not desiredand is connected directly to the ARM core. Did you follow them? However the problem dtaasheet come back and I can’t fix it. They work well for some days.

I am building another board with the diode put correctly, so I will know by next week.
