mcimx6q-sdb/Modifying UART test in IMX6_Platform_sdk

jose0225 — Sun, 17 Jan 2016 09:08:42 GMT

Hello, everyone

I'm now trying to modify UART test in IMX6_Platform_sdk. My purpose is sending 8 word from PC and receive 8 word from IMX6 Board again.

I change some code in uart test. but, if I enter key, UART Test get only one word and process only one word.

My question is what I need to modify for that I can enter long word, not only one word.

and Could I get some hint for this communication?

Thank you.

Hello,

Please use DMA mode to transfer burst of data.

Refer to section 33.8.2 (SDMA test) of "iMX6_Firmware_Guide.pdf".

Have a great day,
Yuri
