Some notes to make a development board for the lpc4357 microcontroller.

Design steps:

• Add Processor crystal and RTC crystal
• Add programming ports: JTAG, USART0, and ISP
• Leave some jumpers or dip switch for the boot pins: P2_9, P2_8, P1_2, P1_1.
• Serial flash. SPIFI 4 bit bidirectional
• USB2.0 OTG
• USB1 Prt
• Ethernet
• VBAT jumper
• USB0 external oscillator is necessary?
• Reset switch.
