Did you follow them? 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. Hello, I further rechecked the schematic and the tested the boards again. But now a problem appeared.
NXP LPC2132/01 ARM7TDMI-S 60 MHz Microcontroller
The LPC datasheet itself says: If it is pulled up and you are not grounding to program, then it would never recognize programming mode. Thanks for any help. Sorry I did not explain the complete situation.
I just received dataheet assembled PCBs and I tried to put in a test program. Datahseet may be the problem – I’ve seen mention of various issues whne VBat has no voltage on it. Rest of the microcontroller may well be ok, but there is no way it can respond to ISP requests now.
JTAG clock to kHz and it works. However the problem has come back and I can’t fix it. I’ve tried to change max. I tried many times and always failed.

I think I know what can be the problem. The crystal is 12MHz with 33pF capacitors.
I’ll have to take a look at the JTAG disabling thing The schematic is good, reset circuit has a 10K pullup and 0. This may sound too simplistic, but I have faced this number of times my self Regards, Prerak On Thu, Aug 20, at Rene Don Disregard my previous answer.
Datasheeh in Sign in Remember me Forgot username or password? The subsequent power stages 5V and 3. A reboot did not help either. Thanks, Girish In l 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.
The voltages at all power pins are ok. But, if somehow the 5V rail could have been affected, it could have damaged the P0. Is there any issue or a trick to get the LPC working, or could it be plain dead K K Yes originally the method I quoted lpc2312 worked for me.
Seems that the oscillator is not working. It looks hard to replace a LPC and I am wondering from where can I buy and get it quickly in canada? No different to FlashMagic, but might save some debugging time.
I scoped the serial port signals and traced with a serial port monitor. I had the same problem when i got some new ‘s with them all and my old one’s, based upon worked fine.
