AM335x omap-serial driver question

here the picture ...

It's weird, I don't why, but the uart cut in half the data and because of that, the device answer with an error in the CRC.

Do you have an idea why the driver would cut in half the data ?

Hi Michael,

Whar kernel are you using? Please note that the Angstrom build is not supported on this forum, you can ask questions about it and the BBB on http://beagleboard.org/Community/Forums

Hi,

It's the Ubuntu build made by Robert C Nelson => http://eewiki.net/display/linuxonarm/BeagleBone+Black#BeagleBoneBlack-LinuxKernel

The version of the Kernel is the 3.8.x but I'm planning to move in the 3.12.x kernel soon ( maybe this week end ).

Do you think that adding the function "wait_for_xmitr(up)" in the function "serial_omap_stop_tx(struct uart_port  port)" will compromise something ?

Also, I'm interesting to know which kernel is more stable ? 3.3 ? or 3.8 ? or 3.12? 3.13 ? I'm only interesting about the serial communication for the moment.

Thank you a lot !

Mick,

Hi Mick,

This forum supports only the TI distributed Linux EZSDK, which currently is v3.2. All other distributions are supported by the community at http://beagleboard.org/Community/Forums.

Thanks Michael, for updating the thread with the solution to your problem.

I also need RS485, but I'll admit I didn't find enough information here to understand how you got it working.

I'm poking at it, but any additional instructions would be helpful. :)

Thanks, I'll have a look. :)
