->The eCos Developer’s Kit package comes with a ROM
-image which provides GDB support for
-the Matsushita(R) AM33 STB System Reference Board. To install the
-GDB stub ROM requires the use of the JTAG debugger and the Flash ROM
-programming code available from Matsushita. An image of this ROM
-is also provided at <TT

->loaders/am33-stb/gdbload.bin</TT
-> under
-the root of your eCos installation.</P

->Ensure that there is a Flash ROM card in MAIN MEMORY SLOT <0>.
-Follow the directions for programming a Flash ROM supplied with
-the programming software.</P

->The final programming of the ROM will need to be done with
-a command similar to the following:</P
