Successfully ported RTEMS 4.10.2 on MVME5500 VME CPU Board

[AJAI KUMAR MEDHAVI]

Hi


I have successfully ported RTEMS on PowerPC MPC7457 Processor Based VME
CPU Board MVME5500-0163 with running sample applications.


This board has two Flash Memory (Flash0 and Flash1). The MotLoad resides
on Flash0 (8MB). For Porting I have placed jumper J8 between pins 1 and 2
to get the board booted from Flash0 (MotLoad).


Then I run following commands to download the sample applications.


1. MVME5500>flashShow

   This command shall show in which Flash MotLoad resides.

2. MVME5500>netShow

   This command shall show which network interface (/dev/enet0 or /dev/enet1
   )is UP. Use UP interface in tftpGet Command.


3. MVME5500>tftpGet -c100.100.100.101  -s100.100.100.110 -g100.100.100.110
-/d/dev/enet1 -fhello.ralf


   Here :

   Client (Target board) IP address : 100.100.100.101
   Server (Host) IP address : 100.100.100.110
   Gateway IP Address : 100.100.100.110


2. MVME5500>netShut


   Note that the 'netShut' command is important: Modern interface devices
   usually feature DMA busmasters and    such a busmaster - if not stopped
   prior to starting RTEMS may corrupt a memory area that was designated as
   buffer space by MotLoad but has been taken over by the newly started
   application.



3. MVME5500>bmw -af2000000 -bf20fffff -c04000000


   Here for Flash0 Memory :

   Destination Starting/Ending Addresses =F2000000/F20FFFFF

   The "-a" and "-b" parameters indicate the start and end addresses of
   where we want to copy from (the source of the copy.) The "-c" parameter
   indicates the location to which the data will be copied. In this example,
   we'll copy the data to location 4000000 in main memory.



4. MVME5500>rs -nr3 -d0
5. MVME5500>rs -nr4 -d0
6. MVME5500>go -a0400000


Finally following comes on Hyerterminal :
