Accessing the `m68k-idp' targets

The way GDB accesses programs intended for the IDP board has changed. With this release, as with the previous one, you should compile programs for this board using `-Tidp.ld' and the `-nostartfiles' option (this option is not necessary for COFF configurations):

m68k-coff-gcc ... -Tidp.ld ...
   or
m68k-aout-gcc ... -Tidp.ld -nostartfiles ...

This yields a binary file which you can you convert to an S-record using objcopy, and then run directly on the IDP board (see section `objcopy' in The GNU Binary Utilities).

We used to provide pieces of a ROM68K tool chain which were needed to allow GDB to communicate with an IDP board over a serial line. Motorola now supplies a boot monitor called ROM68K with which GDB can communicate. To debug a program compiled in the manner described above, type the following on the GDB command line:

target rom68k device 9600

where device corresponds to the device you used to download the binary into the board (for example, `/dev/ttya').
