====== lpc43xx freedev ====== 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. ===== 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 http://support.code-red-tech.com/CodeRedWiki/HardwareDebugConnections?action=show&redirect=CM3_SWD http://knowledgebase.nxp.com/showthread.php?t=385&langid=2 http://mbed.org/users/tecnosys/notebook/lpc1768-programming-via-10pin-jtagsw/ ===== MISC ===== PHY: http://de.mouser.com/_/?Keyword=phy+rmii&FS=True&Ns=Pricing|0 http://de.mouser.com/ProductDetail/SMSC/LAN8720AI-CP/?qs=sGAEpiMZZMuXKgZRMPEonXf54ZBHzE6fcSl1XPn7RJ0%3d http://www.smsc.com/media/Downloads_Public/Data_Sheets/8720a.pdf http://de.mouser.com/ProductDetail/SMSC/LAN8710AI-EZK/?qs=sGAEpiMZZMuXKgZRMPEonXf54ZBHzE6fiUMh8qEXIzY%3d http://www.smsc.com/media/Downloads_Public/Data_Sheets/8710a.pdf http://de.mouser.com/ProductDetail/SMSC/LAN8700C-AEZG/?qs=sGAEpiMZZMuXKgZRMPEonThT6psz%252bC%2fpakrIOYGuNgA%3d http://www.semiconductorstore.com/cart/pc/viewPrd.asp?idproduct=47304 http://newzealand.rs-online.com/web/p/embedded-peripherals/0419956/ http://www.i-vis.co.jp/pdf/wiznet/tcpip_chip/w5100/W5100_AN_SPI.pdf http://www.parallax.com/Store/Accessories/CommunicationRF/tabid/161/ProductID/753/List/0/Default.aspx?SortField=ProductName,ProductName http://www.sparkfun.com/products/8534 http://search.digikey.com/us/en/products/DP83620SQE%2FNOPB/DP83620SQE%2FNOPBTR-ND/2619104 http://search.digikey.com/us/en/cat/connectors-interconnects/modular-jacks-with-magnetics/1442739/page/5?k=MAG%20jack&stock=1&quantity=3&ColumnSort=1000011 http://de.mouser.com/Search/Refine.aspx?Keyword=jack+magnetics lpc21xx board reference design: http://www.microbuilder.eu/projects/LPC2148ReferenceDesign/DesignOverview.aspx lpc21xx linux http://www.thegnar.org/nav/LPCgettingstarted.html isp : http://lpc21isp.sourceforge.net/ tarjetas de desarrollo con LPCs: http://www.embeddedartists.com/products/lpcxpresso/lpc1343_xpr.php JTAG explanation: http://support.code-red-tech.com/CodeRedWiki/HardwareDebugConnections?action=show&redirect=CM3_SWD
