| 1 | This file documents the on board monitor (PPCBUG) configuration used |
|---|
| 2 | to be able to boot the archives located in powerpc-rtems/c/mcp750/bin. |

| 5 | NOTE (by Till Straumann <strauman@slac.stanford.edu>, 2003): |
|---|
| 6 | Apparently, PPCBug fails to shut down the network interface after |
|---|
| 7 | loading an image. This means that the ethernet chip is still able |
|---|
| 8 | to write into its descriptors and network buffer memory which |
|---|
| 9 | can result in the loaded system to be corrupted if that system |
|---|
| 10 | relocates itself!. The proper place to shut down the interface |
|---|
| 11 | would be PPCBug itself or a 'PPCBug startup script' - unfortunately, |
|---|
| 12 | PPCBug doesn't offer such a feature. Therefore, the bootloader |
|---|
| 13 | is by default compiled with the |
|---|
| 14 | #ifdef USE_PPCBUG |
|---|
| 15 | compile-time option ENABLED. It will then use a PPCBug system |
|---|
| 16 | call to shut down the ethernet chip during an early stage of |
|---|
| 17 | the boot process. |
|---|
| 18 | NOTE: THIS (i.e. the system call) WILL FAIL IF YOU USE SOFTWARE |
|---|
| 19 | OTHER THAN PPCBUG TO BOOT THE BSP. In such a case, you must |
|---|
| 20 | recompile with #undef USE_PPCBUG and make sure the ethernet |
|---|
| 21 | interface is quiet by other means. |
