I have seen this and we were pursuing a possible problem with transmission error due to rounding errors inherent in the BAUD calculation with respect to the UART_CLOCK, but even at 115200 the error isn't sufficient to cause this. I only see it occasionally, and it seems to vary by device. Sorry, I don't have a better answer for you. -- Darren Hart Intel Open Source Technology Center Yocto Project - Linux Kernel _______________________________________________ meta-intel mailing list [email protected] https://lists.yoctoproject.org/listinfo/meta-intel
