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

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