Subject: m68k gdb issue with skyeye
Date: Tue, 12 Aug 2008 19:23:00 -0000 [thread overview]
Message-ID: <48A0F96E.7000701@oarcorp.com> (raw)
Hi,
Michael Kang and I have run into something with
m68k gdb and don't know how to fix it. The executable
is for a coldfire mc5272.
With m68k-rtems* (basically m68k-elf) on gdb 6.8,
connecting to the Skyeye gdbserver gives this.
(gdb) tar remote :12345
Remote debugging using :12345
Remote 'g' packet reply is too long:
000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000200000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000
Michael tried gdb 6.8 targeting m68k-linux and
it connects OK.
I tried gdb 6.6 m68k-rtems and it connects and
appears to work OK.
It looks like the way the maximum packet size is
calculated has changed since 6.6 and is dependent
on number of registers.
Does anyone see what the subtle difference is that
is breaking it for m68k-rtems?
