I met issues when using DDR debug file *.mac as K70_MT47H64M16HR-DDR.mac under IAR for K70 Tower. I checked the mac file and modified some commands, but it still not works. I've cheked the mac file in K70 120Mhz src package, it doesn't work, it reports stack error or else. It's used by a key customer, but we cannot resolve the mac file issue, so cannot debug the code in DDR now. Do you help me checking the mac file and write a correct mac file which can be used for debug app under IAR? If it can be use for debug MQX in DDR , it's better.
