AM3352: AM3352,SDIO+MII

Part Number: AM3352

Hi,

Can anyone confirm to me that it is possible to have 3 SDIOs (eMMC, WIFI, SDCARD) and MII forEthernet (LAN8710A) on an AM3352 on Debian Linux.
I used TI PinMux 4 for my pinout.

Hi Christophe,

You can use the TI pinmux tool for that purpose. In case of pin conflict, you will get red error flag.

Also note that e2e forum support Arago Linux that comes with AM335x TI PSDK Linux:

For Debian Linux, support is provided in BeagleBone community:

Hi Pavel,

Mr DARNET has already used the Pinmux tool.

You will find attached the related file.

Could you tell us if it makes sense for you?

What could be optimized ?

Yes, these seems to be correct

I see you have enabled RGMII in your pinmux setup, while LAN8710A support MII/RMII. You can remove RGMII and add MII, this is supported. For Ethernet pins options, check AM335x datasheet section 4.3.6.2 GEMAC_CPSW
