Also if variables are displayed in Variable window. If this is the case I'd suggest you to close the memory window (or set the address to 0), remove variables from Variable Window&nbsp; and reset the MCU or download the code again.</P><P></P><P>BR, Petr</P></BODY></HTML> Tue, 02 Aug 2016 09:05:17 GMT PetrS 2016-08-02T09:05:17Z XXXX Bus Error - No Opcode https://community.nxp.com/t5/MPC5xxx/XXXX-Bus-Error-No-Opcode/m-p/556511#M3921 <HTML><HEAD></HEAD><BODY><P>When I debug TRK-MPC5604B with codewarrior 2.10, I see below issue:</P><P>_start XXXX Bus Error - No Opcode</P><P>Error: Error in Once status register during instruction execution.</P><P>use 'gotil main' command to run until main procedure</P></BODY></HTML> Mon, 01 Aug 2016 11:20:51 GMT https://community.nxp.com/t5/MPC5xxx/XXXX-Bus-Error-No-Opcode/m-p/556511#M3921 langwu 2016-08-01T11:20:51Z Re: XXXX Bus Error - No Opcode https://community.nxp.com/t5/MPC5xxx/XXXX-Bus-Error-No-Opcode/m-p/556512#M3922 <HTML><HEAD></HEAD><BODY><P>Hi,</P><P></P><P style="margin-bottom: .0001pt;">this might be caused by debugger memory window being opened pointing to illegal/uninitialized memory when the debugger is starting.
