VMP1-Post (Optional)
Board description
The VMP1-Post is an optionally available tool which is used for hardware and software
debugging. During the startup process of the VMP1 it provides the user with information
about the status of the boot process by means of a message code similar to the post
codes on the Intel PC. Please note that a Postcode reference list setting out the
meanings of the number codes is available from the local sales office . When the
board has completed the startup process, the VMP1-Post may be used to provide
debug information for software development. The programmer can, therefore, define his
own debug code and send it to the VMP1 by making a byte write command to the first
address of the socket memory area. This address is 0xFFF0 0000 when the boot jumper
J1 of the VMP1 is set and 0xFFF8 0000 when the boot jumper is open.
