I tried to run ddr stress tool on my imx8mqevk borad. I follow the user guild, connect two USB cables, start the tool with administration mode. Then search UART, connect it, load the script, download it. The I got the screen as attached. The calibration or stress buttons turned pale, and the functions are not available. Could anyone tell me what's going wrong?
