Disabling UART0 in Starter kit

Sujata Ingale

Hi All,

I am working on AM335x starter kit with Linux SDK 7.

I am working on USB gadget/device functionality with USB0 port. On the starter kit USB0 is coming with JTAG+UART+USB.

I believe, i need to disable UART0 which comes with USB0 to simplify the USB stuffs. What should be the steps to disable the UART0.

I believe i need to

1. disable uart0 initialisation in kernel

2. plus i want to modify some device drivers for USB gadget functions.

thanks in advance.

This shouldn't be necessary as the UART+JTAG are connected to an FTDI USB converter, which is tied to an on-board USB hub alongside with USB0.

Thanks for your reply.

So, i should be able to detect the AM335x starter kit as a custom device(required application) even though the debug UART is configured.

When i connect my Starter kit with Desktop, it gets detected as serial USB device.

Thanks in advance.

You should see 3 USB devices - 1 serial (debug console), 1 unknown (JTAG, requires driver on PC side), and 1 depending on what device driver you have selected for USB0
