I received 10 Cards which have the MC56F8367 DSC fitted, and began to use Codewarrior to program each with our latest firmware. 6 of the boards programmed fine, but 4 of the boards did not. Codewarrior reported "Unknown Protocol Error". My Codewarrior version is 8.3 (build 091203). Anyone got any ideas as to why this might be happening?</P></BODY></HTML> Mon, 03 Nov 2014 14:58:50 GMT https://community.nxp.com/t5/Digital-Signal-Controllers/Codewarrior-programming-MC56F8367-gives-Unknown-protocol-error/m-p/374020#M326 Signalds 2014-11-03T14:58:50Z Re: Codewarrior programming MC56F8367 gives Unknown protocol error https://community.nxp.com/t5/Digital-Signal-Controllers/Codewarrior-programming-MC56F8367-gives-Unknown-protocol-error/m-p/374021#M327 <HTML><HEAD></HEAD><BODY><P>This is the error message you get if you do not supply power to your board.</P><P>I have never seen this error message in other circumstances.</P><P>However, if there is an electrical problem on the JTAG interface, it could give this message.</P></BODY></HTML> Tue, 04 Nov 2014 23:02:12 GMT https://community.nxp.com/t5/Digital-Signal-Controllers/Codewarrior-programming-MC56F8367-gives-Unknown-protocol-error/m-p/374021#M327 johnlwinters 2014-11-04T23:02:12Z
