DynaView Display Message	Description
	Troubleshooting
Boot Software Part Numbers:	The "boot code" is the portion of the code that is resident in all MPs regardless of what application code (if any) is loaded. Its
LS Flash	main function is to run power up tests and provide a means for downloading application code via the MP's serial connection.
--> 6200-0318-XX	The Part numbers for the code are displayed in the lower left-hand corner of the DynaView during the early portion of the
MS Flash	power up sequence and during special programming and converter modes. See below.
--> 6200-0319-XX
Err2: RAM Pattern 1 Failure	There were RAM errors detected in RAM Test Pattern #1. Recycle power, if the error persists, replace MP.
Err2: RAM Pattern 2 Failure	There were RAM errors detected in RAM Test Pattern #2. Recycle power, if the error persists, replace MP.
Err2:	There were RAM errors detected in RAM Address Test #1. Recycle power, if error persists, replace MP.
RAM Addr Test #1 Failure
Err2:	There were RAM errors detected in RAM Address Test #2. Recycle power, if the error persists, replace MP.

MP: Invalid Configuration	MP has an invalid configuration based on the current software installed
MP Application Memory CRC	App software inside the MP failed its own checksum test. Possible causes: application software in the MP is not complete -
