How to make an embedded system be an USB HOST and DEVICE

[aprado88]

Hello i've this article about USB (https://www.smxrtos.com/articles/usb_art/waysusb.htm) in smxrtos website, however there is a case that isn't listed there.
I need my embedded system to be host when connected to another embedded system and slave when connected to a pc.
Do you have any tips on how to do it? Thank you very much.

USB On-The-Go and Embedded Host

i have a beaglebone and i've read that beaglebone has

Single USB 2.0 type A host port
Dual USB hub on USB 2.0 type mini-A OTG device port
On-board USB-to-serial/JTAG over one shared USB device port
Storage-over-USB or Ethernet-over-USB on other USB device port

Can i use this USB OTG mini-a to do it? Has anyone used it? Isnt there other way?

Hi aprado88:

For making embedded system like this, you first need to decide the processor and OS which you will run on this. And ofcourse you should have USB OTG port on this. Implementation of that what you want is depend on which RTOS you are using. If you share with OS you are using and which board then we can do something on this.

For RTOS, you can refer following articles…
