Can you elaborate on any specific issues with Vbat missing? Can a reversed catch diode of a switching regulator inflict such damage on rest of the circuit?
To have a flash programming enabled, you need to get p0. The battery socket is empty Vbat connected to VSS.
LPC2132/01 ISP issue
I do not know what is wrong? The crystal is 12MHz with 33pF capacitors. The pullup resistor on P0. I just received the assembled PCBs and I tried to put in a test program. I also changed the crystal from a KDS make that had no datasheet, to a Vishay crystal of known parameters, 20pF load capacitance so that the 33pF capacitors matched.

They work well for some days. It looks hard to replace a LPC and I am wondering from where can I buy and get it quickly in canada? Now for the same circuit, one board has this problem and another one can work well with jtag.
Could not stop ARM device?
The voltages at all power pins are ok. Sign in Sign in Remember me Forgot username or password? 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? Is there any issue or a trick to get the LPC working, or could it be plain dead And at this point, no sensors are connected and P1.
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. Dataeheet have probably checked for every possible pin that could send the LPC into some other mode and prevent it from responding to ISP. Create free account Forgot password?
However after I changed them back, the error was still there. If it is pulled up and you are not grounding to program, then it would never recognize programming mode. A reboot did not help either.

Thanks lpf2132 advance for any idea. 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. Anyone has experience about it? Yes originally the method I quoted earlier worked for me. The subsequent power stages 5V and 3.
Errata documents do not mention anything relevant to this problem. Rest of the microcontroller may well be ok, but there is no way it can respond to ISP requests now. Read-Only Author erik malund Posted 4-Aug This pin when low at startup, makes pins P1.
