Ticket Name: CCS/TDA2: new tda2x EVM , Blackhawk XDS560v2-USB test connection failed Query Text: Part Number: TDA2 Tool/software: Code Composer Studio a new tda2x EVM , Blackhawk XDS560v2-USB System Trace Emulator (this have connect to tda3x evm successful ,now i just change to tda2x evm ) i see the pdf the power supply is 12V 7 A ,But I use 12v 2.5A replace; if i launch the target configuring ,it stop much time like follow Responses: Hi Shuai, Have you tried the Test Connection option in the ccxml file to check if the JTAG scan chain path is okay? This should give you an idea if the basic connection is fine. If the Test Connection also fails, I would suggest you to update your power supply to the recommended EVM power supply and then give it another try. Thanks and Regards, Piyali Hi :Piyali Have you tried the Test Connection option in the ccxml file to check if the JTAG scan chain path is okay? I uploaded 3 pictures, the one in the middle is try to test connection , then it stop there like the picture along time. i think it doesnot finished, then i close the test connection window , CCS is hanging out. BESTWISHES SHUAI Hi SHUAI Thanks for confirming! Can you please try with a different EVM power supply (7A)? Thanks and Regards, Piyali Another thing to try is to reduce the TCK clock frequency and check if the issue is resolved for you. You can get the TCK clock frequency in the ccxml file, when you click on "Blackhawk XDS560v2 USB System Trace Emulator 0" (First line in the advanced tab) Thanks and Regards, Piyali Hi :Piyali i try EVM power supply (7A) , but it also cannot connect. BEST wishes Hi Shuai, Thank you for trying the experiment! Have you been able to try the Lowering of TCK clock? From the picture of your evm I could not quite read the sysboot pin settings. Can you also please make sure the sysboot pin settings are SYSBOOT(SW2)[1:16] = 00000000 10000001 ? Thanks and Regards, Piyali Hi Piyali SYSBOOT(SW2)[1:16] = 00000000 10000001 ? sysboot pin settings are right try the Lowering of TCK clock? i donot know how to do this , follow is the ccxml file Hi Piyali JTAG TCLK frequency i try legacy 10.368MHZ limit and faster 35.0 Mhz limit . both the same ,even JTAG no conect with evm is the same Hi Piyali I try to I installed CCS in the virtual machine and tried to connect ,,follow is the result!

[End: Blackhawk XDS560v2-USB System Trace Emulator_0] I don't think you SYSBOOT is configured correctly either. Can you make sure it boots fine from an MMC, then remove the card and try the JTAG connection again? You can just quickly try to mimic the SYSBOOT from TDA3x that works for you. Thanks Alex Hi Alex Can you make sure it boots fine from an MMC . How to do? SYSBOOT(SW2)[1:16] = 00000000 10000001 ? is set right . anyother to do ?? could your Describe the operation steps! BEST WISHES JTAG TCLK frequency i try legacy 10.368MHZ limit and faster 35.0 Mhz limit .
