Hello,
The USB problem has been spotted by the TI support here: “Linux/PROCESSOR-SDK-AM335X: USB gadget issue with RT kernel” https://e2e.ti.com/support/arm/sitara_arm/f/791/p/675060/2486199 But it looks like they are not going to send the patch to the kernel.org, because they are not seeing the problem in the mainline of 4.16. But the mainline is not an RT kernel. I am also have the problem as I am using Sancloud Beaglebone Enhanced with build in WIFI. The WIFI chip is connected to the am3358 by USB. So I have disabled the rtl8xxu driver from being loaded. Best regards On Saturday, March 10, 2018 at 6:12:39 PM UTC+1, Alexander Rössler wrote: > > Exactly the same here.
