I have probably checked for every possible pin that could send the LPC into some other mode and prevent it from responding to ISP. Ed Healy The following article may help: I am sure LPC is no different.

LPC Datasheet(PDF) – NXP Semiconductors

However the problem has come back and I can’t fix it. 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. I do not know what is wrong? Errata documents do not mention anything relevant to this problem. Important information This site uses cookies to store information on your computer. The host keeps sending 0x3F ‘? Thanks, Girish In l I just received the assembled PCBs and I tried to put in a test program.


Thanks for any help.

LPCFBD64 Datasheet

I’ll have to take a look at the JTAG disabling thing There was a issue with the power supply circuit in the begining, the first stage 15V switching regulator catch diode was connected in ddatasheet bad footprint used by the PCB designerand I had to replace the regulator. JTAG will not be blown. The schematic is good, reset circuit has a 10K pullup and 0. So datasheett 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 checked all the pin usage again, and found that I am using pin P1. Can you elaborate on any specific issues with Vbat missing? Voltages on all power pins are OK. This site uses cookies to store information on your computer. Now, dztasheet there anything else I could be missing, in terms of logic levels on certain pins that I need to lpd2132 on startup?

And then i changed i back again and it still works. I am building another board with the diode put correctly, so I will know by next week. The subsequent power stages 5V and 3. I donot have idea what action cause it damage.

NXP LPC2132/01 ARM7TDMI-S 60 MHz Microcontroller

Hello, I further rechecked the schematic and the tested the boards again. A reboot did not help either. The clock shows low on one pin and high on the other. The can be programmed by ISP and can run program when datasheett on. Rest of the microcontroller may well be ok, but there is no way it can respond to ISP requests now.

They work well for some days.

Thanks in advance for any idea. That may be the problem – I’ve seen mention of various issues whne VBat has no voltage on it. By continuing to use our site, you consent to our cookies. It looks hard to replace a LPC and I am wondering from where can I buy and get it quickly in canada?

Does anyone have any insight? Girish In l But, if somehow the 5V rail could have been affected, it could have damaged the P0. Can a reversed catch diode of a switching regulator inflict such damage on rest of the circuit? K K I found the solution! Products Download Events Support Videos.

JTAG clock to kHz and it works. The voltages at all power pins are ok.
