Hello @Zoe-man onboard SDIO is already connected to onboard SPI flash.
It’s not exposed externally.

Regards.

Yes，I got it.But how about your WiFi module connect to board by SDIO interface or PCIe interface?

I want to use wifi module of SDIO interface on your board,could I?

4

@Zoe-man the wifi module is connected via PCIe, you can access SD card IO with Edge2 IO board.

5

Yes,But how to connect,can you show me HW connection physical diagram?

Please check the schematic:

Thank you very much!But I have another question that if there anyone bring up SDIO3.0 module successfully on RK3588S board?Actually,I’m very worry about our module cannot bring up on RK3588S.
Because I saw the module is PCIe interface in schematic document ,but our module is SDIO interface and our module is not pin to pin with your board.

8

Another question，As I known，edge2 have two config(8G+32G and 16G+64G),which one is better for SDIO3.0 performance?

9

we have not seen any such success stories at the moment.

IO performance of peripherals is agnostic to memory/storage configuration, only onboard eMMC will be slightly faster read/write for 64GB configuration.

@Zoe-man Before repo sync, modify the default.xml file to change Google’s URL address to Tsinghua University, as follows:

gouwa@Server:~/project/khadas/aosp/.repo/manifests$ git diff
diff --git a/default.xml b/default.xml
index f48a988..b8cb9da 100644

@Zoe-man Execute the ping github.com command to see if it can ping. If even this website cannot ping, then there is no solution.

$ ping github.com
