Summary: Suggestion: Documentation clarifications for ARM7 PID
Product: eCos
Version: 1.2.1
Platform: All
OS/Version: ARM
Status: UNCONFIRMED
Severity: normal

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
