Retransmissions

Hello,

Im getting different behavior on my SoC depending on what power source I use. For example I tend to get alot of retranmissions from client to server if I have them powered with an USB hub but only one tranmission between a client and server if I have them powered by computer. Can I manipulate this in kconfig file?

All the best

Hello Ossian,

That is strange, and no I do not think it is not something that could be manipulated by configurations. Are you using a USB 3 Hub, though? They are known to be a bit noisy which can cause issues.

Regards,

Hello and thanks for the reply,

Im using a "linocell super charger 50W" usb hub that outputs 5v 2,4A 12W max on each port, I dont think it allows for any data transfer which might cause issues? Just using it to power my cards. So theres no "energy saving mode" kind of configuration in kconfig?

I don't think there are any that depends on the input voltage.

I don't think that should be an issue. Though is your application using the USB for data transfers?

You could check if the USB hub is giving you an unstable supply, but this is a bit odd.
