I’ve also been able to pass the 9th bit on the output data, but so far it has not appeared useful. In other words, RTS signal comes too late. All times are GMT uarh If you need to reset your password, click here. Having a problem logging in? Open Source Consulting Domain Registration.
I can always fall back on the arduino “software serial” interface method, but it would be nice to be able to interface directly through the pi with a simple C program or perl script.
Separating amba-pl device driver from linux kernel.
serial: amba-pl Add basic rs support – Patchwork
Now if I cat the device file, I get the expected output. By combining these techniques you can ignore up to two junk bits before the stop bit.
Have you turned on crtscts? Join our community today! I read that the pl uart can possibly do 2 stop bits, but it appears that maybe that isn’t readily available on the GPIO pins without some serious hacking? This book contains many real life examples lp011 from the author’s experience as a Linux system and network administrator, trainer and consultant. You are currently viewing LQ as a guest. I’ve got it working now.
This thread discusses non standard baud rates by adjusting the UART clock. Note that registered members see fewer ads, and ContentLink is completely disabled once you log in.
Could you guide me to the correct lines in the yart code to add delay? Linux – Kernel This forum is for all discussion relating to the Linux kernel.

CONFIG_SERIAL_AMBA_PL011: ARM AMBA PL011 serial port support
The time now is For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. The required hardware flow control is causing headaches. The oscilloscope reveals that RTS is set to active i. We use kernel 3. I’ve already read that by modifying one of the system clocks, the baud rate can be changed to something non standard.
