Only RCLK has nothing happen. Errata documents do not mention anything relevant to this problem. Now for the same circuit, one board has this problem and another one can work well with jtag. I do not know what is wrong? Sorry I did not explain the complete situation. If it is pulled up and you are not grounding to program, then it would never recognize programming lpc21332.
Previous 1 2 Next. Rest of the microcontroller may well be ok, but there is no way it can respond to ISP requests now.
The host keeps sending 0x3F ‘? The pullup resistor on P0.
K K Yes originally the method I quoted earlier worked for me. To have a flash programming enabled, you need to get p0. I have probably checked datashee every possible pin that could send the LPC into some other mode and prevent it from responding to ISP. I also tried resetting the controller by shorting the reset capacitor, after power up. I am sure LPC is no different.
Thanks, Girish In l I found the solution! Posted by “Charles R. Ed Healy The following article may help: I had the same problem when i got some new ‘s with them all and my old one’s, based datasneet worked fine.
I just received the assembled PCBs and I tried to put in a test program.
Girish In l Arduino Robotics Lonnie Honeycutt. The can be programmed by ISP and can run program when power on. So when I attempt to flash the program, I put the jumper in place, and rest of the times it is pulled high without the jumper. I donot have idea what action cause it damage. I don’t now the reason for this. Introduction to Microcontrollers Mike Silva. Anyone has experience about it?

That may be the problem – I’ve seen mention of various issues whne VBat has no voltage on it. JTAG clock to kHz and it works. Can you lpf2132 on any specific issues with Vbat missing? Thanks for any help.

The subsequent power lp2c132 5V and 3. The clock shows low on one pin and high on the other. I could switch this input to a nearby pin that is defined as output in my application, but before I perform some surgery on the board, does anybody have any experience with using the traceport and ISP together on the same board?
Could not stop ARM device? Kim Berthelsen I had the same problem when i got some new ‘s with them all and my old one’s, based upon worked fine.
The documentation is not clear whether it affects ISP mode. I am building another board with the diode put correctly, so I will know by next week.
