  • [SOLVED] JTAG connection with i.MX RT1050 EVKB

    We have a custom board project equipped with two i.MX RT1051.
    We would like to use the JTAG connection, instead of the SWD, in order to link the two MCUs, as shown here
    en.wikipedia.org/wiki/JTAG#Daisy-chained_JTAG_(IEEE_1149.1)

    so we can only use one program/debug connector.
    The preliminary step for us is to make the JTAG connection work on EVKB (taking care to pull up the JTAG_MOD signal). However, the connection is not established.

    We wonder where we're wrong. Is there any special command or parameter for J-Link? We wonder if the RT105x supports JTAG for programming and debugging or just boundary scan.
    best regards
