Hi folks,
I am experiencing a strange situation: I recently purchased some LPC2134 parts;
I added them to a board that I know to work (I usually put LPC2132 on it and
they work without problems), so when I connect the flashmagic tool or the
lpc2000 flash utility, i can not read the device id/device signature (and of
course I can not program them). I checked with an osciloscope and the clock is
working, pin P0.14 remains grounded during reset, reset is controlled by PC,
device is selected in the tools, and the command arrive to the microcontroller
Rx0 pin, but they remain in silence...
So it is possible that I have parts without bootloader?
best regards,
Pedro Ignacio Martos

Hi Pedro,
very unlikely, the bootloader is programed during final test of the devices.
Impossible? That word I'd rather not use. Have seen stranger things than this, for example dummy devices (no silicon inside) delivered to customers. So, it is within the range of possibilities but if so, we should see more of this in the forum soon.

It's quite strange,... Have you tried to connect using JTAG?
