Hi All,
Does Linux kernel tree has any standard utilities to test any low level UART driver?
What do you mean by "low level UART driver"? bcm63xx_uart.c
Have you tried one of the many different userspace serial port tools?
I tried only minicom. Could you let me know the best userspace serial port tools.
What doesn't work with minicom? That's a really good tester given that it exercises the tty layer a lot.
Those are usually the best test of a system, along with some simple loop-back tests if you have the proper hardware plugged into the serial port.
What driver are you trying to test? I’m trying to test Broadcom 63xx integrated uart driver.
What currently does not work with it? The driver has been around for a very long time, it should be really stable. thanks, greg k-h
