Hardhat Linux 2.4.2 on IBM Walnut w/AMC ICE

[Curry, Diane]

Hi Everyone,
  I'm running Monta Vista's 2.4.2 source release on an IBM rev D Walnut
along with AMC's PowerTap (jtag interface) and MWX-ICE software.  In
order to get breakpoints recognized by the ICE, I had to bracket the
code that changed DBCR0 with #ifdef CONFIG_KGDB and #endif statements.
The symptom was that breakpoints set early in initialization, prior to
the execution of ppc4xx_setup_arch, were hit, but once ppc4xx_setup_arch
set the IDM and TDE bits, breakpoints were no longer hit.  Is this
reasonable? Has anyone had similar issues with other ICE units?  Thanks
in advance, for any help.
