Part Number: AWR1243

Hi expert,

Because AWR1243 does not contain JTAG function, then how to do standard boundary scan on this chip?

Regards,

Hi

The JTAG pins for boundary scan are available in the datasheet

thank you

JTAG is not available on AWR1243. Is it a mistake on the document?

Thanks.

Hi Allen,

Because only the TI firmware package and ICD API document are allowed to run on the AWR1243, JTAG debugging of the MSS core is not supported. However, JTAG boundary scan functionality is supported - we have BSDL models released on the AWR1243 tools page: www.ti.com/.../toolssoftware and that assumes JTAG pin functionality.

I think we should clarify this in the datasheet.

Please let me know if this answers your question on this topic.

Thanks,
Randy
