In previous releases /dev/ttyGS0 used to be there but now it is not, did something change in Yocto?

how about /dev/ttyGS1?

how about using FW 14.1?

pmark · May 31, 2023, 4:03pm

Thanks, but that is not an option at this point.

It looks like linux 4.14 changed to use configfs for the usb_gadget,

I have not figured out what the script is actually doing ?
but this seems to be where the configuration takes place?

pmark · June 1, 2023, 1:37pm

It seems that at_usb2 is the same as ttyGS0
on the Ubuntu host /dev/ttyUSB3 receives from WP7702 /dev/at_usb2
echo -e “HELLO” > /dev/at_usb2

That is fine by me to use /dev/at_usb2 instead of /dev/ttyGS0,
but is there any documentation describing how all this relates?

jyijyi · June 2, 2023, 3:32am

I don’t see any information regarding this in here:

But I think you can use /dev/at_usb2 for the raw data port.

pmark · June 2, 2023, 1:13pm

Thanks,
/dev/at_usb2 seems to be working.

I still have /dev/ttyHS0 and /dev/ttyHS1 even though the guide says ttyMSMx ?

are you using UART in data mode?

I don’t see /dev/ttyHS port in WP77 R15:

I am using ATT firmware
Not sure what you mean by UART in data mode?

Does your project need to use uart?

pmark · June 2, 2023, 2:50pm

Yes it is using both of them and it works fine with the ttyHSx i was just wondering why it is not ttyMSMx as the documentation says?

I don’t see problem.
you can use the FW here:
