 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. 4 bit bidirectional
+  * Serial flash. SPIFI 4 bit bidirectional
   * USB2.0 OTG
+  * USB1 Prt
   * Ethernet
-  * RTC 32KHz clock
+  * VBAT jumper
-  * VBAT
+  * USB0 external oscillator is necessary?
-  * USB0 external oscillator is necessary.
   * Reset switch.
+===== JTAG =====
+DBGEN can be 0 for disabling brakepoints. Put a solder jumper there. http://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&ved=0CDQQFjAA&url=http%3A%2F%2Finfocenter.arm.com%2Fhelp%2Ftopic%2Fcom.arm.doc.faqs%2Fka3759.html&ei=chtsT77ZIo_ptQaAiMWYAg&usg=AFQjCNH2y7lRzzak0uwf68sCvupT62Y-Yg
