ORRECTIVE ROCEDURES
1 When CFE is not able to initialize the system and reach the console prompt, output on the serial boot console
may be used to help debug the initialization sequence. When the Cer2 message appears, a cache error has
occurred. This frequently occurs when the BCM1250 is either undercooled or is in a low-voltage situation.
Ensure that the correct voltage and cooling is being provided. For other status/error message descriptions,
refer to the Common Firmware Environment (CFE) Specification document.
2 There is no output coming from the serial boot console. Because CFE uses serial port 0 by default, ensure that
a standard 9-pin RS232 null-modem cable connection is being used. Also ensure that the terminal program is
set to a baud rate of 115200, 8-bit, no parity, no flow control. Finally make sure the output is not being routed
to the PromICE console.
