From: Hollis Blanchard To: embedded list Date: 29 Oct 2002 13:18:19 -0600 Message-Id: <1035919100.1013.1226.camel@granite.austin.ibm.com> Mime-Version: 1.0 Sender: owner-linuxppc-embedded@lists.linuxppc.org List-Id: Has anyone had problems with hardware breakpoints from external debuggers? I'm using RISCWatch, which sets DBCR0 and IAC1 for me (yes I've verified that). I'm then using 'echo > /proc/sys' to invoke my code. However by the time I get to my sysctl proc handler, DBCR0 has been reset from 0x80810000 to 0x00010000, hence IAC1 is ignored. I don't see much use of DBCR0, other than initialization and then save during exception prologs and then restore during task restore. Can anyone point me to where it might be reset? -Hollis ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
