Part Number: AM3352
Other Parts Discussed in Thread: TPS65217

Tool/software: Linux

i'm using am3352 capture usb webcam picture.

when i used kernel 4.1.6 , i got more problem (DMA busy , usb frozen....).

and find some post like below:

e2e.ti.com/.../223368

e2e.ti.com/.../556181

but the problems are not fixed .so i change kernel version to 4.14.79

and now i get new problem ....

my usb driver is not boot

---------------------------------------------------------------------------------------------------------------

when kernel 4.1.6 booting i can see below message:

Hi Bin :

Thanks for your help ,

maybe i konw what happen ,

i look at /lib/modules/, but only has old kernel "4.1.6-g52c4aa7" directory ,

so my usb driver is never start , right?

today i'm going to try , thank you very much.

My first glance didn't spot anything missing. The script chkusb.sh would point out if any kernel config is wrong.

Hi Shawn,

Your attached kernel defconfig is from the kernel source code, which is not exactly the same as that running on your board, so it doesn't tell what is configured for your board.

But anyway, something is fundamentally wrong in your filesystem, which causes the musb drivers are failed to load. Below are the links to the documentation for how to create SD card from Processor SDK Linux prebuilt binaries and how to re-build the Processor SDK kernel. Please follow the links to re-create your rootfs.
