Debugging NXP LPC11xxLV parts

What is special about LPC11xxLV ?

The NXP LPC11xxLV parts are Cortex-M0 based MCUs with Low-Voltage Input (1.65 V to 1.95 V). This low voltage input means that special debug support is required within the tools and debug probe. The IO pads of these parts are NOT 3.3V tolerant and it is therefore fairly easy to damage the parts by applying over voltage to pads.

For more information on the LPC11xxLV, please visit NXP's website: http://www.nxp.com/products/microcontrollers/cortex_m0/lpc1100lv/

What version of the tools do I need to use?

Support for building projects for the NXP LPC11xxLV parts was added in Code Red IDE v5.0.12. However you MUST use Code Red IDE v5.0.14 (or later) in order to safely debug these parts.

What debug probes can I use ?

Debugging of LPC11xxLV parts can only be carried out using Red Probe+.

If you try to debug using LPC-Link, you will see an error telling you that no suitable debug adapter can be found. This is because LPC-Link does not support the necessary low voltage operation.
