Firmware update required

Please make sure you have updated your LPCXpresso to the latest firmware to enable the mbed flash disk interface


The LPC11U6x are an ARM Cortex-M0+ based, low-cost 32-bit MCU family operating at CPU frequencies of up to 50 MHz. The LPC11U6x support up to 256 kB of flash memory, a 4 kB EEPROM, and 36 kB of SRAM. The ARM Cortex-M0+ is an easy-to-use, energy-efficient core using a two-stage pipeline and fast single-cycle I/O access. The peripheral complement of the LPC11U6x includes a DMA controller, a CRC engine, one full-speed USB device controller with XTAL-less low-speed mode, two I2C-bus interfaces, up to five USARTs, two SSP interfaces, PWM/timer subsystem with six configurable multi-purpose timers, a Real-Time Clock, one 12-bit ADC, temperature sensor, function-configurable I/O ports, and up to 80 general-purpose I/O pins.
