I suppose that you want /usr/ports/devel/m68kgdb? It's got one in there if you've got a visionICE from EST. We're using it for 68360 targets and MVME147 systems as well. If you are running Bug32 GDB can support it out of the box over a serial port. Works great with DDD too. > There is one available for Linux and am thinking of > porting those to FreeBSD. Is it gonna be difficult? Fortunately, with FreeBSD, you will have some assistance from the new ppbus driver which offers several new interfaces useful for bit-banging including the ppi 'geek' port :) There is a feature providing programmable "microsequences" which looks promising. A very useful GDB enhancement would the ability to program target flash memory through this interface. We'll be working on updating the crossm68k toolchain pretty soon, possibly to EGCS, and supporting PowerPC as well. Patches welcome :) Cheers, Jerry Hicks wghicks@bellsouth.net jerry.hicks@glenayre.com > Thanks in advance for any suggestions, > > Suttipan Limanond. > To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
