ZUBoard 1CG - Power Up with Power Connected issue

olivier_lb
olivier_lb over 1 year ago

We are trying to set up the “Power Up with Power Connected” feature by swapping out the resistors to avoid having to use a push button, as listed in the Hardware User manual guide:

We have performed this change on our devboard, but it still requires the push button to be pressed in order for the board to boot.

Please advise us on how we could fix this issue.

Thank you,

Olivier L-B

EDIT: The proposed change by narrucmot seems to have fixed our issue.

    Unfortunately, this is a known issue with ZUBoard. The workaround is to install a resistor and capacitor to create R-C delay at power on. We recommend installing a 200K resistor at R212 and a 4.7uf capacitor…
