This should help caleb and david with their factory test/programming stuff.

Comment 1 Stein David 2009-02-25 11:11:06 UTC
Would like to use this for Fab4 PB3 and MPQ.  Can this be completed in the next week?
Comment 2 Caleb Crome 2009-02-25 20:48:55 UTC
Why do you need this vs. a regular UART?  It may be possible to compile in and test by then, but I wouldn't bet the build on it.

-C
Comment 3 Stein David 2009-02-25 20:54:24 UTC
Because the regular UART is not available on Fab3 once it is in plastic.
Comment 4 Blackketter Dean 2009-02-25 21:31:15 UTC
David needs a way to get to the console during factory test without having to use the touch screen or IR, while in the plastic.  (I don't know the specific station he needs this for...)

On the baby, he can do this with the battery connector, but not so with fab4.

Just need somebody with access to a fab4 poky system to add the module and configure to enable console.  Should be pretty straightforward.

Added in r4540

Support for: FDTI and Keyspan USA-19 usb-serial-adapters

Serial settings: 9600/8/N/1

After plugging usb-serial-adapter into Fab4 it takes up to 10 seconds until login prompt appears.

r4541 changes serial settings to 115200/8/N/1
