Hello Nick, Are you using gdb from rpm or from svn repository? Also are you using 2.6.18-92.el5 kernel or svn repository? I don't remember I still support 2.6.18-92.el5. I suggest trying gdb from svn repository and 2.6.27.10 kernel.
Have you seen boot message when you run minicom for your target? -caz -----Original Message----- From: nickcheng [mailto:[email protected]] Sent: Tuesday, May 26, 2009 12:05 AM To: [email protected] Subject: [Kgdb-bugreport] start kgdb-light error Hi, I configure the host and target as the settings on website respectively.
