Some users want to use SDIO signals on M.2 connector for WiFi card. In default linux bsp, there is no problem using imx8mp-evk-usdhc1-m2.dts, usdch1 driver can normally loaded, and detect WiFi module, But default android bsp doesn't support it, even if using corresponding device tree, usdch1 driver can NOT be loaded correctly, Because default android bsp doesn't load pwrseq_simple.ko, which is used by usdhc1 node. Detailed steps on enabling usdhc1 in the attached document, hope it can help users who wants to use M.2 SDIO WiFi card. [Note] For other android bsp version, users can also refer to the steps in attached document.   Thanks! Regards, Weidong Sun

Based on i.MX8MN-EVK And Linux 5.4.70_2.3.0 BSP As an example of NXP Bluetooth Bluetooth application, this article describes how to use Bluetooth to realize file transfer between windows PC and i.MX8MN-EVK (linux), and between Android mobile phone and i.MX8MN-EVK. The test architecture used in this example is as follows: weidong_sun_0-1623680389346.png The following steps are for the application example: Step 1 Preparation  --Downloading DEMO Image For i.MX8MN-EVK  --Downloading uuu tool  --Compiling L5.4.70_2.3.0 BSP for i.MX8MN-EVK  --Copying rootfs to the DEMO Image directory  --Modifying example_kernel_emmc.uuu as uuu programming script  --Programming images to i.MX8MN-EVK board  Booting i.MX8MN-EVK board Step 2 Loading WIFI/BT driver and Enable Bluetooth Step 3 File Transter between Windows 10 PC and i.MX8MN-EVK board Step 4 File Transter between Android Mobile and i.MX8MN-EVK board [Summary] More detailed information, see attachment, please!
