This may sound too xatasheet, but I have faced this number of times my self Regards, Prerak On Dayasheet, Aug 20, at If it is pulled up and you are not grounding to program, then it would never recognize programming mode.

Thanks in advance for any idea. I checked all the pin usage again, and found that I am using pin P1. K K I found the solution!

I think I know what can be the problem. Read-Only Author erik malund Posted 4-Aug The voltages at all power pins are ok.


The clock shows low on one pin and high on the other. I found the solution!

LPC2132 Datasheet

The LPC datasheet itself says: And at this point, no sensors are connected and P1. Apparently, this trace port affects functions of only certain pins of course, that is not desiredand is connected directly to the ARM core.

The schematic is good, reset circuit has a 10K pullup lpd2132 0. K K Yes originally the method I quoted earlier worked for me. I tried many times and always failed. Can you elaborate on any specific issues with Vbat missing?

The subsequent power stages 5V and 3. JTAG will not be blown. I scoped the serial port signals and traced with a serial port monitor.

LPC2132/01 ISP issue

Thanks, Girish In l Important information This site uses cookies to store information on your computer. Introduction to Microcontrollers Mike Silva. But now a problem appeared. The crystal is 12MHz with 33pF capacitors. They work well for some days. However after I changed them back, the error was still there. I’ll have to take a look at the JTAG dayasheet thing Rene Don Disregard my previous answer.


It looks hard to replace a LPC and I am wondering from xatasheet can I buy and get it quickly in canada? I’ve tried to change max.

JTAG clock to kHz and it works. Rest of the microcontroller may well be ok, but there is no way it can respond to ISP requests now. I am sure LPC is no different. I also changed the crystal from a KDS make that had no datasheet, to a Vishay crystal of known parameters, 20pF load capacitance so lcp2132 the 33pF capacitors matched.
