    Difference of JTAG communication failure between with external pull-up and without

    inoue-junichi_1625121

      The customer has two boards that they have S6E2C1AH0AGV2000A.

      One of them has external pull-up for JTAG.

      The other one doesn't has external pull-up.

       

      I thought that there is no difference of JTAG communication failure because there are internal pull-up,

      but the board having external pull-up is less communication failure than no pull-up.

      Is this phenomenon correct?
