Hi all I am trying a debug my code using emulator and get the message saying..Data verification failed at address: 0x0c0000 Expected: 0x000668a0, Found: 0x00000000 i think probably due to my following part of my code...and my ldf.. segment("seg_dmda")float dm val[50]={ #include"make.dat"; }; and the ldf... seg_rth { TYPE(PM RAM) START(0x00008000) END(0x000080ff) WIDTH(48) } seg_init { TYPE(PM RAM) START(0x00008100) END(0x000810f) WIDTH(48) } seg_pmco { TYPE(PM RAM) START(0x00008110) END(0x00008fff) WIDTH(48) } seg_pmda { TYPE(PM RAM) START(0x00009800) END(0x00009fff) WIDTH(32) } #ifdef __cplusplus seg_ctdm { TYPE(DM RAM) START(0x0000C000) END(0x0000C0ff) WIDTH (32) } seg_ctdmend { TYPE(DM RAM) START(0x0000C100) END(0x0000C1ff) WIDTH(32) } seg_dmda { TYPE(DM RAM) START(0x0000C200) END(0x0000Cfff) WIDTH(32) } #else seg_dmda { TYPE(DM RAM) START(0x000C0000) END(0x000CCfff) WIDTH (32) } #endif seg_heap { TYPE(DM RAM) START(0x000Cd000) END(0x000Cdbff) WIDTH(32) } seg_stak { TYPE(DM RAM) START(0x000Cdc00) END(0x000Cdfff) WIDTH(32) } Im using 21065l But i could not figure out what the problem could have been....

Hi Sanjana, Does your emulator work correctly while executing code from internal memory? I too had a similar problem while working with APEX-ICE ( USB based emulator for ADSP-21061.Everytime while I used to invoke the emulator, it used to alert me with a message of the very same time as what you are experiencing at your end. What confused me more was that, the scan test for emulator used to get through correctly. So I never suspected the emulator connectivity. However ultimately, I thought of analyzing the noise level on the JTAG lines running into my target board. I did find sufficient amount of ringing and ground bounce. After referring to an application note ( I think it was EE- 68 ), I introduced a 4.7K pullup on TMS, TCK and TDI lines. That too did not help much. Later I changed the pullup value to 10K. Also I pulled down the /TRST line low. Things started working fine after that. Also earlier I was driving my target board with a SMPS. Later due to high frequency noise, I adopted a linear power supply. Do check if any of the above gets applicable in your case.
