ORRECTIVE ROCEDURES
1 When CFE is not able to initialize the system and reach the console prompt, the four-character alphanumeric
LED display may be used to help debug the initialization sequence. When the Cer2 message appears, a cache
error has occurred. This frequently occurs when the BCM1125H is either undercooled or is in a low-voltage
situation. Ensure that the correct voltage and cooling is being provided. For other LED message descriptions,
refer to the Common Firmware Environment (CFE) Specification document.
2 There is no output coming from the serial boot console, but the four-character LED displays CFE . 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.
