Hi experts,
I was recently working with i.MX 8M Evaluation Kit, while the board's debug UART ports get very slow response to the keyboard inputs.
For device, I tried:
1) the preloaded Android image with EMMC boot;
2) a self-built fsl-image-validation-imx image with SD boot.
For the host side, I tried both mac OS and ubuntu-16.04 with minicom.
Right now, both images can boot up, and the UART ports can print the system logs correctly.
However, if I want to interact with the UART port like typing any command in the UART port
evk_8mq:/ $
, the UART becomes very slow, and even no response to my input after a while.
I'm wondering if anyone runs into this scenario, or knows what would be the possible reason?
Thank you in advance.
Simon

Hi Simon
one can try Demo Images from
Getting Started with the i.MX 8M Evaluation Kit|NXP
and try to update UART-USB cp2105 drivers which EVK uses
USB to UART Bridge VCP Drivers - Silicon Labs
Schematics
Design Files for the i.MX 8M Evaluation Kit (EVK)(REV 0)
i.MX 8M Evaluation Kit | NXP

Thanks for the answer. After I update several things the UART works fine so I guess it should be a driver issue.
