The default serial port settings are 38400,8,N,1. RedBoot also supports minimal flash management on the EB40. However, since the flash device (AT29LV1024) is so small (only the upper 64K is available for general use), only the simple flash write command 'fis write' is supported.</P ><P >The following RedBoot configurations are supported: <DIV CLASS="INFORMALTABLE" ><A NAME="AEN5266"><P ></P ><TABLE BORDER="1" CLASS="CALSTABLE" ><THEAD ><TR ><TH ALIGN="LEFT" VALIGN="TOP" >Configuration</TH ><TH ALIGN="LEFT" VALIGN="TOP" >Mode</TH ><TH ALIGN="LEFT" VALIGN="TOP" >Description</TH ><TH ALIGN="LEFT" VALIGN="TOP" >File</TH ></TR ></THEAD ><TBODY ><TR ><TD ALIGN="LEFT" VALIGN="TOP" >ROM</TD ><TD ALIGN="LEFT" VALIGN="TOP" >[ROM]</TD ><TD ALIGN="LEFT" VALIGN="TOP" >RedBoot running from the board's flash boot sector.</TD ><TD ALIGN="LEFT" VALIGN="TOP" >redboot_ROM.ecm</TD ></TR ><TR ><TD ALIGN="LEFT" VALIGN="TOP" >RAM</TD ><TD ALIGN="LEFT" VALIGN="TOP" >[RAM]</TD ><TD ALIGN="LEFT" VALIGN="TOP" >RedBoot running from RAM with RedBoot in the flash boot sector.</TD ><TD ALIGN="LEFT" VALIGN="TOP" >redboot_RAM.ecm</TD ></TR ><TR ><TD ALIGN="LEFT" VALIGN="TOP" >ROMRAM</TD ><TD ALIGN="LEFT" VALIGN="TOP" >[ROMRAM]</TD ><TD ALIGN="LEFT" VALIGN="TOP" >RedBoot running from RAM, but contained in the board's flash boot sector.</TD ><TD ALIGN="LEFT" VALIGN="TOP" >redboot_ROMRAM.ecm</TD ></TR ></TBODY ></TABLE ><P ></P ></DIV ></P ></DIV ><DIV CLASS="SECT2" ><H2 CLASS="SECT2" ><A NAME="AEN5290">Initial Installation Method</H2 ><P >This development board comes with ARM's debug tool, Angel, installed in flash. At this time, Angel will not be replaced. Rather, RedBoot will be placed in the alternate half of flash. Switch SW1 is used which monitor to boot. Selecting SW1 to "lower mem" will choose Angel. Select SW1 to "Upper mem" for RedBoot once it has been installed.</P ><P >Set SW1 to "lower mem" and connect serial port A to a host computer. Using GDB from the host and Angel on the board, download the RAM mode image of RedBoot to the board. SW1 should then be set to "upper mem" just before starting RedBoot using the 'cont' command. Once RedBoot is started, the Angel session must be interrupted (on Linux this can be done using ^Z). Follow this by connecting to the board using minicom at 38400-8N1. At this point, RedBoot will be running on the board in RAM. Now, download the ROMRAM mode image and program it to flash. <TABLE BORDER="5" BGCOLOR="#E0E0F0" WIDTH="70%" ><TR ><TD ><PRE CLASS="SCREEN" ><TT CLASS="USERINPUT" ><B >arm-elf-gdb redboot_RAM.elf</B ></TT > (gdb) <TT CLASS="USERINPUT" ><B >tar rdi s=/dev/ttyS0</B ></TT > Angel Debug Monitor (serial) 1.04 (Advanced RISC Machines SDT 2.5) for AT91EB40 (2.00) Angel Debug Monitor rebuilt on Apr 07 2000 at 12:40:31 Serial Rate: 9600 Connected to ARM RDI target.
