[Bug 20309] New: Suggestion: Documentation clarifications for ARM7 PID


http://bugs.ecos.sourceware.org/show_bug.cgi?id=20309

           Summary: Suggestion: Documentation clarifications for ARM7 PID
           Product: eCos
           Version: 1.2.1
          Platform: All
        OS/Version: ARM
            Status: UNCONFIRMED
          Severity: normal
          Priority: low
         Component: Porting Guide
        AssignedTo: jifl at ecoscentric dot com
        ReportedBy: anonymous at egcs dot cygnus dot com


1.  /doc/tutorials/ecos-tutorial/arm-hardware-setup.htm
You state that LK6 pins 7-8 chooses FLASH vs. ROM mode.  
Actually, it chooses whether to use U12/8-bit socket or 
U13/16-bit socket.  LK6 pins 5-6 is used to write protect 
whichever socket is selected by pins 7-8.

U13 is stuffed with an AT27C1024 which is an EPROM (not a flash), 
so it is not possible to flash a new image onto it without a 
device programmer.  U12 is stuffed with a 29C040A which can be 
flash programmed in place.

See p. 28 (Sec. 2.5.1, p. 2-20) of 
http://www.arm.com/Documentation/UserMans/PDF/TDS_1-4.pdf

2.  Given that I do not have an EmbeddedICE to use on the JTAG 
port or a device programmer, how do I restore the Angel.rom image 
in the 8-bit flash?  If there is a procedure to do this, it 
should be included at the end of 
/doc/tutorials/ecos-tutorial/arm-hardware-setup.htm

3.  The "ARM7 PID" is now called the "ARM Development Board"

Near the bottom of http://www.arm.com/Documentation/Guides/ shows
the "ARM Development Board" was formerly known as the PID7T.

It might be beneficial to mention the name change near the top of 
/doc/tutorials/ecos-tutorial/arm-hardware-setup.htm
