Ultrazed USB Device Mode

adiaz04 over 8 years ago

How do I put the Ultrazed SOM/IO carrier combo in USB Device Mode?

My goal is to be able to connect the board to a PC and access the eMMC.

Hi,
Is your intentions to just set the hardware to device mode and then see it on your PC? (No applications running)
From my limited knowledge in this area, In a standalone enviroment I had to run an application to setup in my case a PicoZed to where I could view it from my windows PC/write to it.

Hi Josh - my ultimate goal is to be able to format and partition the eMMC without having to boot into linux on the device. I figued I might be able to put the board in device mode so that the pc can just see the eMMC as an external usb drive or something which would allow me to format the eMMC from my pc.

You would need firmware running on the UltraZed to implement USB MSC class to respond to the USB commands from the host. There's no automagic passthrough from USB to eMMC. That would all have to be done via firmware running on the processor.
