In other words, RTS signal comes too late.
Is there any chance to add a short delay to the driver e. One UART is used to communicate with a bluetooth module. Join our community today! View LQ Wiki Contributions.

This book contains many real life examples derived from the author’s experience as a Linux system and network administrator, trainer and consultant. Linux – Kernel This forum is for all discussion relating to the Linux kernel. Separating amba-pl device driver from linux kernel. FYI, we use libbt to connect to the Broadcom-based bluetooth device. By basically taking the software delay designed to skip the stop bit and multiplying by 2, I can ignore the 9th bit.
Have you turned on crtscts? Could you guide me to the correct lines in the driver code to add delay?
Are you new to LinuxQuestions. Now if I cat the device file, I get the expected output. 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. Find More Posts by Michael Any help would be very much appreciated! Open Source Consulting Domain Registration. 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 interrupt bit appears after the 8 bits of data, but before the stop bit. We use kernel 3.
If you’d like to contribute content, let us know. The time now is This thread discusses non standard baud rates by adjusting the UART clock. I’ve also been able to pass the 9th bit on the output data, but so far it has not appeared useful.
9 bit serial – Raspberry Pi Forums
We developed a customized hardware board based on an ARM processor. After modifying uadt uart clock in cmdline. Dear all, I hope you can help me. If you need to reset your password, click here.

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 aba hacking? By combining these techniques you can ignore up to two junk bits before the stop bit. Having a problem logging in? This is the relevant part of libbt:
