    Greetings,

    AN2339 (STR91xx Hardware Development Getting Started) seems to have a conflict. On page 14 the document recommends a pull-down resistor for the JTRST of the JTAG port. However, on page 18 the example schematic shows a pull-up resistor on that pin. Can anyone clear this up?

    Thanks,

    David

    Hello david.c.fly,

    It is an error in the documentation. We have already posted to correct it in the next version. In fact, we recommend a pull-up resistor for the JTRST pin and not a pull-down.

    Thank you to mention it.

    Best regards,

    mirou.
