Colibri USB Host 15k pulldown on own carrierboard necessary yes/no


atm we are designing our own carrierboard for the colibri imx6ull 1gb IT module 07324256 V1.1A.

For our Project we need two USB 2 Host ports. Questions is are the 4 15k external pulldown resistors necessary?

in this Document called “Colibri Computer Module
Carrier Board Design Guide
” the 15k resistors where removed.

Thanks for you Help

Best regards

The мentioned pull down resistors are only needed for Colibri PXAxxx modules. If the board is designed for Colibri iMX6ULL they are not necessary.
