CON1 (SIP2-254) and USB-DM3 usage

Banana Pi SBCs design BPI-M2+/BPI-M2 Zero/BPI-P2 Zero(H3)
1

I have need to utilize maximumI’m looking at M2+ schematics and see that H3 have 4 USB:

  • USB0 connected as OTG (micro USB)
  • USB1 and USB2 exposed as dual USB A connector
  • USB3 exposed on CON1

Can anyone tell me if it is possible to use USB3 or reconfigure USB0 as device ?

I need at least 3 USB ports in my device.

I tested this on another H3 board a while ago, configuring OTG as host port and using Armbian’s new BSP kernel with countless patches on top (please keep this in mind since SinoVoip uses a horribly outdated kernel on their OS images for BPi M2+):

Test commands used on OPi Plus 2E:

iozone -e -I -a -s 100M -r 4k -r 16k -r 32k -r 512k -r 1024k -r 16384k -i 0 -i 1 -i 2
iozone -e -I -a -s 4096M -r 16384k -i 0 -i 1

Other Armbian users confirmed USB 3.0 GbE dongles reaching 350 Mbits/sec on the OTG port (configured as host) so using the right settings H3’s OTG port seems pretty capable.

we find CON1, and you could read it http://forum.banana-pi.org/t/possible-header-configurations-and-rtc-question/1862?u=bpi_q

@tkaiser, @BPI_Q again many thanks for testing. I’m waiting for my OPi PC Plus and will test this approach.
