Hello,

...

Did anybdy is having idea abt usb console in u-boot i.e development of usb serial emulation(CDC_ACM).I am using smdk2440 development board.

There is a driver 'drivers/serial/usbtty.c' in the u-boot tree, in case you mean something like that.

And in case someone wants to port the linux CDC_ACM driver to Uboot, I was working on the CDC-Ethernet support in U-boot and have the complete patch series here, it is based on the gadget layer of Linux also. It is not mature yet, but at least it already works on some ARM cores. I am thinking of making it a separate branch in the u-boot-usb tree.

IIRC, OpenMoko uboot already has support for usb serial emulation (CDC_ACM). The basic cdc_acm patch came from the handhelds.org SX1 project, and Harald Welte added support for s3c2410 USB device controller driver for u-boot I was able to test CDC ACM on smdk24a0 after making some modifications to the above patch. Regards, Pradeep
