Troubleshooting and error codes

Problem	Possible Reason	Solution
During Power Up	Primary Booter does not start	The ROM image area in the boot flash device is not empty (LEDs switch to green/off after POST). Enforce primary booter execution via PCR register (see "Controlling Boot Process" page 4-13).
During Power Up	Application in ROM image area does not start / LEDs switch to yellow/yellow after green/off.	A software reset occurred while executing the ROM image. Configure ROM image so that firmware disables the watchdog before executing it (see "SYPCR Register" page 4-9). Add software watchdog support to application in ROM image area.
After Power Up	LEDs remain yellow/yellow after power-up	Wrong switch settings. Verify switch settings (all switches must be in OFF position).
During Operation	PCI error when trying to communicate with the firmware via the 4 MByte PCI window	The address translation of the PCI window is not enabled. Allow firmware to enable address translation by setting bit 3 (value 816) in mailbox register 6 (offset 46816) of PowerSpan. This can be done either before resetting the module or while the primary booter is running. Enable address translation by setting bits 31 and 30 (hex. value C000000016) in target image 1 control register (offset 10016) of PowerSpan.
