ColdFire/68K Microcontrollers and ProcessorsのトピックMCF5235 bdm documentation https://community.nxp.com/t5/ColdFire-68K-Microcontrollers/MCF5235-bdm-documentation/m-p/134935#M1532 <HTML><HEAD></HEAD><BODY><SPAN>Hello,</SPAN><BR /><BR /><SPAN>I am currently working on better patch to support the coldfire 2/2M processors with the m68k-bdm [1]. Working on that project I found the following information in the manuals:</SPAN><BR /><BR /><SPAN>Coldfire 2/2M Users Manual: 7-22, page 159:</SPAN><BR /><SPAN>Control Register Map for Read Control Register (RCREG) command:</SPAN><BR /><SPAN>RAMBAR0 = $C04</SPAN><BR /><BR /><SPAN>MCF5235 Manual: 3-8, page 697:</SPAN><BR /><SPAN>Control Register Map for Read Control Register (RCREG) command:</SPAN><BR /><SPAN>RAMBAR = $C05</SPAN><BR /><BR /><SPAN>From testing I known that the second value is correct but I am still wondering why it was chosen this way. Does that mean that a debugger can't treat all Coldfire 2 cores in the same way? I wanted to make only a distinction between 2 and 2M cores (the later one having the MAC registers).</SPAN><BR /><BR /><SPAN>Regards,</SPAN><BR /><SPAN>Christian Walter</SPAN><BR /><BR /><SPAN><SPAN>[1] </SPAN><A class="jive-link-external-small" href="https://community.nxp.com/external-link.jspa?url=http%3A%2F%2Fsourceforge.net%2Fprojects%2Fbdm%2F" rel="nofollow" target="_blank">http://sourceforge.net/projects/bdm/</A></SPAN><P>Message Edited by wolti on <SPAN class="date_text">05-06-2006</SPAN><SPAN class="time_text">04:00 PM</SPAN></P></BODY></HTML> Sun, 07 May 2006 03:59:20 GMT wolti 2006-05-07T03:59:20Z MCF5235 bdm documentation https://community.nxp.com/t5/ColdFire-68K-Microcontrollers/MCF5235-bdm-documentation/m-p/134935#M1532 <HTML><HEAD></HEAD><BODY><SPAN>Hello,</SPAN><BR /><BR /><SPAN>I am currently working on better patch to support the coldfire 2/2M processors with the m68k-bdm [1].
