How do I make the LWB5+ SDIO 1.8v work with an iMX8M DVK?
If you choose SDIO VDDIO 1.8v mode in the Sterling-LWB5+, you need to make sure that the host platform won’t probe 3.3v.
You need to change the wire of port 1 and 3 in Q1601 in iMX8M DVK, so that it won’t probe 3.3v during SDHC module detection.
Please check the attached schematic file and need this modification.
