Interfacing ZedBoard with MSP430

I am a newbie to Zedboard. I am trying to interface Zedboard with MSP430 launchpad through UART. At present, I'm using Uartlite IP in the PL and have embedded it in the Linux kernel that runs on the PS. My aim is to write a driver for interfacing with MSP430 board and include it in the kernel. Can anyone help me do the same?

Hi Roctaves,

I think the driver you are looking for already exists. Take a look at this Wiki article which describes which kernel driver needs to be enabled and what entry to place into the device tree:

http://www.wiki.xilinx.com/Uartlite+Driver

Once you have that in place, your user space application would probably need to implement some higher level protocol in order to communicate something meaningful across the UART interface.

Hi Kevin,

As you suggested, I have placed the LKM in the device tree and tested UART loopback on PC real-term. But I didn't understand what you actually meant by higher level protocol, since the protocol is the driver itself and is already written in the UARTLite IP. Could you clarify the same ?

Thanks,
Rocktaves
