Therefore the earlier documentation for the EP7211 Development Board can be considered equivalent, but with the following changes:</P ><P ></P ><UL ><LI ><P >The first serial port is silk screened as "UART 1" on the EP7211 Development Board, but is silk screened as "Serial Port 0" on the EP7212 Development Board. Similarly "UART 2" is silk screened as "Serial Port 1" on the EP7212 Development Board.</P ></LI ><LI ><P >JP2 (used to control reprogramming of the FLASH) is not silkscreened with "Boot Enable".</P ></LI ><LI ><P >To setup the EP7212 Development Board for use with the ARM Multi-ICE JTAG debugging interface unit, it is necessary to connect TEST0 and TEST1 of the EP7212 to ground. On the Development Board, this is accomplished by placing shorting blocks on JP47 and JP48. When the shorting blocks are fitted, the board can only be operated through the Multi-ICE - debugging over a serial line is not possible.</P ></LI ><LI ><P >Pre-built GDB stubs are provided in the directory <TT CLASS="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 "Cirrus Logic processor variant" option (CYGHWR_HAL_ARM_EDB7XXX_VARIANT) from the EP7211 to the EP7212. This can be selected in the <SPAN CLASS="emphasis" ><I CLASS="EMPHASIS" >eCos Configuration Tool</I ></SPAN > , or if using ecosconfig, can be set by uncommenting the user_value property of this option in ecos.ecc and setting it to "EP7212".</P ></LI ></UL ></DIV ><DIV CLASS="NAVFOOTER" ><HR ALIGN="LEFT" WIDTH="100%"><TABLE SUMMARY="Footer navigation table" WIDTH="100%" BORDER="0" CELLPADDING="0" CELLSPACING="0" ><TR ><TD WIDTH="33%" ALIGN="left" VALIGN="top" ><A HREF="setup-arm-ep7211.html" ACCESSKEY="P" >Prev</A ></TD ><TD WIDTH="34%" ALIGN="center" VALIGN="top" ><A HREF="ecos-user-guide.html" ACCESSKEY="H" >Home</A ></TD ><TD WIDTH="33%" ALIGN="right" VALIGN="top" ><A HREF="setup-arm-ep7312.html" ACCESSKEY="N" >Next</A ></TD ></TR ><TR ><TD WIDTH="33%" ALIGN="left" VALIGN="top" >Cirrus Logic ARM EP7211 Development Board Hardware Setup</TD ><TD WIDTH="34%" ALIGN="center" VALIGN="top" ><A HREF="appendix-target-setup.html" ACCESSKEY="U" >Up</A ></TD ><TD WIDTH="33%" ALIGN="right" VALIGN="top" >Cirrus Logic ARM EP7312 Development Board Hardware Setup</TD ></TR ></TABLE ></DIV ></BODY ></HTML >
