Linux/BEAGLEBK: How to store the data received data from uart to beaglebone sd card ?

Hi, thanks for your post.

This is a pretty generic Linux question as our drivers provide standard interfaces for these functions. The UART can be accessed by TTY port and the SD Card as a block device. You'll need to write an application to open both and format the files that uses these standard interfaces. I'm sorry, but we can't provide more specifics on this application and there are a number of ways to do it.

I hope this is helpful to you. Thanks.
