Dear all,
I have a program that needs to open /dev/ttyS0, I use core-image-minimal-imx6qsabresd.sdcard by yocto.
After booting, I don't find /dev/ttyS0, I check linux-2.6-imx/drivers/tty/serial/imx.c (http://git.freescale.com/git/cgit.cgi/imx/linux-2.6-imx.git ) only ttymxc0.
Does something I miss?
In the latest releases of our BSP, the UART devices are named as ttymxcX. If you need to send data over a UART port you havet to open one of those devices.
Best Regards,
Alejandro
