Set attributes error

Hi,

Is this applicable for multimedia image used with tk1 with ixora carrier board?

I have tried to run this command

stty -F /dev/ttyTHS1 9600 -echo

but I’ve get error:

[ 61.194185] serial-tegra 70006040.serial: configured baud rate is out of range by -6
[ 61.202009] serial-tegra 70006040.serial: Failed to set baud rate
[ 61.208102] serial-tegra 70006040.serial: Uart HW init failed, err = -5
stty: /dev/ttyTHS1: Input/output error

I need to use UART2 as mentioned in the article example

Please advise.

Regards,
Rama

Hi @rama.aloufee ,

thank you for sharing your used version.

We are aware of the issue, and our team is working on a fix. As soon as the fix is ready I’ll let you know.

I am sorry that there is no better answer at the moment.

it is working now, I dont know what is new!

I was planning to use usb-serial driver instead, so I get back to my oe-core folder and add the driver of usb-serial to the kernel " using menu config", then re-bitbake the image. then when I flashed it to TK1 UART2 is defined and working well.

did you add anything new?

Hi @rama.aloufee ,

Thank you for the update.

Nothing has changed on our side, so I guess your solution is viable. Thank you for posting it here.
