john young Posted October 31, 2022 Share Posted October 31, 2022 looking to see if you have a JTAG stand alone probe for TI processors, specifically their ARM based processors (I'm using the TMS570LC4370)....I'm almost positive i used the JTAG H2 a few years back for interfacing to their TIVA series (ARM) processors... appreciate any info/feedback. thank you Link to comment Share on other sites More sharing options...
0 JColvin Posted November 2, 2022 Share Posted November 2, 2022 Hi @john young, The JTAG HS2 might be able to do some debugging for that TI Processor, though I am uncertain about it as Digilent has not tested any of our JTAG modules with TI processors as far as I am aware. The JTAG HS2 is compatible with IEEE 1497.7-2009 Class T0 - Class 4 whereas the TI processor lists IEEE 1149.1. Based on this page from IEEE, https://standards.ieee.org/ieee/1149.7/3936/, it appears that IEEE 1497.7 some roots in IEEE 1149.1 and provides backward compatibility, though I am not familiar enough with IEEE material to give any insight on the actual details of what is specifically being referred to by backward compatibility. There are several things that I am not able to determine from the TI datasheet that I would recommend looking into: - Physical/electrical compatibility. Table 4-22 lists 7 different pins that I can't find a clean matching configuration pattern of JTAG connections that TI lists here: https://software-dl.ti.com/ccs/esd/documents/xdsdebugprobes/emu_jtag_connectors.html. The JTAG HS2, nor other Digilent JTAG devices have a nTRST, TEST, or RTCK pin. - If there is other evidence of Digilent JTAG devices being used since they are not listed in the 3rd party adapters section of the above page I linked nor this page here: https://software-dl.ti.com/ccs/esd/documents/xdsdebugprobes/emu_jtag_connectors.html. - What kind of JTAG functions you need; Digilent JTAG modules do not cover IEEE 1497.7-2009 Class T5 which addresses "data transfers concurrent with scan, supports utilization of functions other than scan....".
