How to use the peripheral functions such as UART and USB on a SABRE Board for Smart Devices Based on the i.MX 6 Series.
While enabling the HDMI ,the UART will become unstable and output the error symbol.
I use the default FTDI USB to RS232 function.
Also,I set the following parameters.
setenv bootargs video=mxcfb1:dev=hdmi,1920x1080M@60,if=RGB24,bpp=32 androidboot.console=ttymxc1 enable_wait_mode=off no_console_suspend
The attached file is the log.
What should I set to avoid that the uart will not output the error symbol through the FTDI?
Also,I have enabled the usb function. However,I can not use adb command to connect the SABRE Board.
What should I do to enable adb functions between the SABRE Board and PC while using HDMI function?
