>The Cirrus Logic EP7212 Development Board is almost identical
92 
to the EP7211 Development Board from a hardware setup viewpoint,
93 
and is based on the same port of eCos. Therefore the earlier documentation
94 
for the EP7211 Development Board can be considered equivalent, but
95 
with the following changes:</P

>The first serial port is silk screened as "UART 1" on
102 
the EP7211 Development Board, but is silk screened as "Serial Port
103 
0" on the EP7212 Development Board. Similarly "UART 2" is silk screened
104 
as "Serial Port 1" on the EP7212 Development Board.</P
105 
></LI
106

107

108 
>JP2 (used to control reprogramming of the FLASH) is not
109 
silkscreened with "Boot Enable".</P

111

112 
><P
113 
>To setup the EP7212 Development Board for use with the
114 
ARM Multi-ICE JTAG debugging interface unit, it is necessary to
115 
connect TEST0 and TEST1 of the EP7212 to ground.  On the Development
116 
Board, this is accomplished by placing shorting blocks on JP47 and
117 
JP48. When the shorting blocks are fitted, the board can only be
118 
operated through the Multi-ICE - debugging over a serial line is
119 
not possible.</P
