HW Device Description
System Clocks PPMC-275 introduces two clocks: TCLK and SysCLK.
SysCLK is used for the CPU, while TCLK is used for the MV-
64360. Both clocks are described as TCLK_RATE and
SYSCLK_RATE macros in the pmc275.h file. Make sure that
these frequencies are described correctly.
(SYSCLK_RATE = 133000000; TCLK_RATE = 133000000)
Serial Ports PPMC-275 supports two serial ports (RS232rt0, Port1). For a
single CPU BSP Serial Port 0 is used, while in case of a Dual
CPU BSP, Serial Port 0 is the console for CPU0 and Serial Port
1 is the console for CPU1
PCI Bus PPMC-275 supports a 64-bit bus running at 66 MHz.
Ethernet Interfaces PPMC-275 contains two Ethernet controllers, which can be
configured to the RMII interface.
PPMC-275 provides two ways to connect VxWorks to the network interface
for network operations.
