Hello fellow PPC developers. My name is Max MacLean, a new subscriber to this list. Thanks for taking my call. Since I cannot find a way to easily search the archives, I'll ask directly.
Is anyone working on or aware of a patch the MPC52xx_uart driver to provide a 'low_latency' option. I want to be able to do this (in c++) struct serial_struct ss; if(ioctl(m_iSerial, TIOCGSERIAL, &ss)) { ss.flags |= ASYNC_LOW_LATENCY; ioctl(m_iSerial, TIOCSSERIAL, &ss)) } or from command line type setserial /dev/ttyPSC1 low_latency I am trying to get data from my fifo into Linux faster. I am currently seeing a 3-8 msec latency between characters read in the uart and arrival at the tty. It seems like it's a problem that has been solved on other platforms best regards, Max __________________________________ Maxwell MacLean | Senior Firmware Engineer SYMBOTIC LLC
