http://stackoverflow.com – I'm currently trying to compile a Linux USB UART driver, which is provided here: http://www.exar.com/connectivity/uart-and-bridging-solutions/usb-uarts/x... The driver consists of 2 header files and one large C file. These are the contents of the Makefile: obj-m := vizzini.o KERNELDIR ?= /lib/modules/$(shell uname -r)/build PWD := $(shell pwd) EXTRA_CFLAGS := -DDEBUG=0 all: $(MAKE) -C $(KERNELDIR) M=$(PWD) modules_install: $(MAKE) -C $(KERNELDIR) M=$(PWD) modules_install clean: rm -rf *.o *~ core .depend .*.cmd *.ko *.mod.c .tmp_versions vtty This is the erro (HowTos)

USB Driver Compilation Error 17 weeks 4 days ago

I'm currently trying to compile a Linux USB UART driver, which is provided here: http://www.exar.com/connectivity/uart-and-bridging-solutions/usb-uarts/x...

The driver consists of 2 header files and one large C file.

I'm currently trying to run the bellow driver in linux-3.8.3 on Exar xr21v1414 http://www.exar.com/connectivity/uart-and-bridging-solutions/usb-uarts/x..., but when i install the driver vizzini.ko, it arise the follow error:

[ 162.650000] usbserial: USB Serial support registered for Vizzini USB serial port [ 162.650000] vizzini 1-1.4:1.0: Vizzini USB serial port converter detected [ 162

I've got a board based on the Vortex86DX CPU which is an x86 based microcontroller. It has five 16550A UARTS, four (COM1-COM4) of which are at the usual io port addresses (0x3f8, 0x2f8, 0x3e8, 0x2e8) but the fifth (COM9) is at 0x010, irq 9.

Vortex86DX

The first four UARTS are detected, I have no problem with them. The problem is that I can't get the fifth one (COM9) to work in Linux.

i Have omap4 and It has total 4 UART port from that i want to do some read write operation on UART 4 port/pin from kernel space so how can i do that?

after days of searching I found this link and seems it has what I've been looking for ! I couldn't install it , I'm so new linux user can u give me a hand in this :( please

readme file says :

To compile the driver you need to have source codes of your OS kernel. Default Makefile is searching for kernel source codes in "/usr/src/linux" folder to compile the driver.

I'm working on setting up the pinmux on a BeagleBone so that I can access multiple UARTS. The OS is Angstrom Linux (the demo image, if that helps).
