TMS320F28034: sequence or mechanism to control the JTAG Pins

Hi Gerald,

I am not knowledgeable about ecus, could you give more details about your setup? What connections are available?

Best Regards,

Ben Collier

Hi Ben,

Which setup details do you need? Do you mean the HW setup?

Kind regards,

Gerald

Hi Gerald, 

I am not familiar with ecus, and I am not sure what a HW setup refers to in this context. If you would like to share the HW setup, that might be a good starting point. I am sorry I cannot be more helpful at this time.

Best Regards,

Hi,

I understand, we would also appreciate it if you can refer us to the right support for this type of concern as well. I will share the hardware setup as soon as the customer provides/respond. Thank you.

Best regards,

Gerald

Hi Gerald,

This is the right place for support with JTAG problems, I just need more information about the specific setup and what exactly you are trying to do. Just curious, are you trying to program the device or are you trying to use breakpoints? Is the device locked somehow?

Best Regards,

Ben Collier

Hi Ben,

Please see below for our customer response:

"I need to close the JTAG while in production Software, And I think it shall be controlled with the CSM module am I right ?"

Thank you and kind regards,

Gerald

Hi Gerald,

That is correct, you can lock the JTAG with the CSM, although the capabilities vary across devices. I am not sure how it works for TMS320F28034, so I am reaching out to our expert for the CSM to provide you with further support.

Best Regards,

Hi Ben,

Thank you. We will wait for further information. I hope to hear more.

Best regards,

Gerald
