Therefore the earlier documentationfor the EP7211 Development Board can be considered equivalent, butwith the following changes:</P><P></P><UL><LI><P>The first serial port is silk screened as "UART 1" onthe EP7211 Development Board, but is silk screened as "Serial Port0" on the EP7212 Development Board. Similarly "UART 2" is silk screenedas "Serial Port 1" on the EP7212 Development Board.</P></LI><LI><P>JP2 (used to control reprogramming of the FLASH) is notsilkscreened with "Boot Enable".</P></LI><LI><P>To setup the EP7212 Development Board for use with theARM Multi-ICE JTAG debugging interface unit, it is necessary toconnect TEST0 and TEST1 of the EP7212 to ground. On the DevelopmentBoard, this is accomplished by placing shorting blocks on JP47 andJP48. When the shorting blocks are fitted, the board can only beoperated through the Multi-ICE - debugging over a serial line isnot possible.</P></LI><LI><P>Pre-built GDB stubs are provided in the directory <TTCLASS="FILENAME">loaders/arm-edb7212</TT> relative to the root of your eCos installation</P></LI><LI><P>When rebuilding the GDB stub ROM image, change the "CirrusLogic processor variant" option (CYGHWR_HAL_ARM_EDB7XXX_VARIANT)from the EP7211 to the EP7212. This can be selected in the <SPANCLASS="emphasis"><ICLASS="EMPHASIS">eCos Configuration Tool</I></SPAN>, or if using ecosconfig, can be set by uncommenting the user_valueproperty of this option in ecos.ecc and setting it to "EP7212".</P></LI></UL></DIV><DIVCLASS="NAVFOOTER"><HRALIGN="LEFT"WIDTH="100%"><TABLESUMMARY="Footer navigation table"WIDTH="100%"BORDER="0"CELLPADDING="0"CELLSPACING="0"><TR><TDWIDTH="33%"ALIGN="left"VALIGN="top"><AHREF="setup-arm-ep7211.html"ACCESSKEY="P">Prev</A></TD><TDWIDTH="34%"ALIGN="center"VALIGN="top"><AHREF="ecos-user-guide.html"ACCESSKEY="H">Home</A></TD><TDWIDTH="33%"ALIGN="right"VALIGN="top"><AHREF="setup-arm-ep7312.html"ACCESSKEY="N">Next</A></TD></TR><TR><TDWIDTH="33%"ALIGN="left"VALIGN="top">Cirrus Logic ARM EP7211 DevelopmentBoard Hardware Setup</TD><TDWIDTH="34%"ALIGN="center"VALIGN="top"><AHREF="appendix-target-setup.html"ACCESSKEY="U">Up</A></TD><TDWIDTH="33%"ALIGN="right"VALIGN="top">Cirrus Logic ARM EP7312 Development BoardHardware Setup</TD></TR></TABLE></DIV></BODY></HTML>⌨️ 快捷键说明
