Activate 3 ports on the Ethernet switch of the MT7628

Thu Mar 05, 2020 11:07 pm

How do I activate more than one Ethernet port on the MT7628 of the Vocore2 ultimate. I am interested in activating 3 ports:
1 for the MT7628 running a custom application that communicates with 2 external ethernet devices
1 for external device to connect to using RJ45 on the ultimate dock (already done and ready to go)
1 for a separate single board computer that I can connect the ethernet TX & RX pins to directly using PCB traces between the external SBC and the MT7628

set register 0x1000003c bit 20,19,18,17,16 to 0, you will have five ethernet port. in same time, the SD card slot is disabled.
This chip only allow two modes of ethernet port, one is 5 ethernet port; another is one ethernet port.
If you want 3 ethernet port also SD card, have to disable i2c and i2s interface, and use their pins(check vocore.io/v2.html about pinmux) and apply this patch https://github.com/Vonger/vocore2/blob/ ... si2c.patch

Return to VoCore2/Lite/Ultimate
