Getting Started with NXP-based Wireless Modules on i.MX 8M Quad EVK Running Android 10 OS
3.5.6 Enabling SDIO on M.2 connector
The M.2 connector on AW-CM358MA wireless module supports SDIO interface for Wi-
Fi whereas the i.MX 8M Quad M.2 connector supports PCIe interface by default. This
section shows how to rework i.MX 8M Quad resistors to support SDIO on M.2 connector
for the AW-CM358MA module.
Note:
The hardware rework instructions enable the SDIO support from an SD card
connector to an M.2 connector. A software change is also required to make the feature
fully functional. Please refer to
Section 4.3 "Enabling uSD/M.2 88W8987-based wireless
to enable the SDIO on M.2 using DTB file. Please note that the SDIO on the
MicroSD card slot will be disabled after the rework.
