| 10 | The BSP is built and tested on the 4.7.1 and 4.7.99.2 CVS RTEMS release. |

|---|
| 12 | I believe in valuable real-time programming, where technical neatness, |
|---|
| 13 | performance and truth are. Any suggestion, bug reports, or even bug |
|---|
| 14 | fixes (great!) are welcome so that I still believe what I believe. |

| 81 | ======= |
|---|
| 82 | |
|---|
| 83 | 1) The BSP is tested with the 60x bus mode instead of the MPX bus mode. |
|---|
| 84 | ( No jumper or a jumper across pins 1-2 on J19 selects the 60x bus mode) |
|---|
| 85 | |
|---|
| 86 | 2) On the mvme5500 board, Ethernet 1 is the Gigabit Ethernet port and is |
|---|
| 87 | front panel only. Ethernet 2 is 10/100 BaseT Ethernet. For front-panel |
|---|
| 88 | Ethernet2, install jumpers across pins 1-2 on all J6, J7, J100 and |
|---|
| 89 | J101 headers. |
|---|
| 90 | |
|---|
| 91 | 3) Enable SROM initialization at startup. (No jumper or a jumper across |
|---|
| 92 | pins 1-2 on J17) |
|---|
| 93 | |
|---|
| 94 | In fact, (if I did not miss anything) the mvme5500 board should function |
|---|
| 95 | properly if one keeps all the jumpers at factory configuration. |
|---|
| 96 | One can leave out the jumper on J30 to disable EEPROM programming. |
|---|

| 98 | Notes |

|---|
| 101 | BSP BAT usage |
|---|
| 102 | ---------------------- |
|---|
| 103 | DBAT0 and IBAT0 |
|---|
| 104 | 0x00000000 |
|---|
| 105 | 0x0fffffff 1st 256M, for MEMORY access (caching enabled) |
|---|
| 106 | |
|---|
| 107 | DBAT1 and IBAT1 |
|---|
| 108 | 0x00000000 |
|---|
| 109 | 0x0fffffff 2nd 256M, for MEMORY access (caching enabled) |
|---|
| 110 | |
|---|
| 111 | UPDATE: (2004/5). |
|---|
| 112 | The BSP now uses page tables for mapping the entire 512MB |
|---|
| 113 | of RAM. DBAT0 and DBAT1 is hence free for use by the |
|---|
| 114 | application. A simple 1:1 (virt<->phys) mapping is employed. |
|---|
| 115 | The BSP write-protects the text and read-only data |
|---|
| 116 | areas of the application. Special acknowledgement to Till |
|---|
| 117 | Straumann <strauman@slac.stanford.edu> for providing inputs in |
|---|
| 118 | porting the memory protection software he wrote (BSP_pgtbl_xxx()) |
|---|
| 119 | to MVME5500. |
|---|
| 120 | |
|---|
| 121 | |
|---|
| 122 | The default VME configuration uses DBAT0 to map |
|---|
| 123 | more PCI memory space for use by the universe VME |
|---|
| 124 | bridge: |
|---|
| 125 | |
|---|
| 126 | DBAT0 |
|---|
| 127 | 0x90000000 PCI memory space <-> VME |
|---|
| 128 | 0x9fffffff |
|---|
