I have some doubts about the real need of externall pull-ups for SDIO lines used for a WiFi Module (in our case JODY-W2 by Ublox).
Due to reviewing some EVKs, I have seen that external pull-ups are not used for the SDIO lines, and we wonder if just with the configuration of the pin, in the NXP Pinmux tool, as "internal pull-up enabled" it would work.
Is that right? Would that be enough?
Or on the contrary, Is it necessary to add the pullup?
Many thanks in advance.
