AM3358: USB does not resume after Deepsleep

Ayla Shiva

Part Number: AM3358

Hi TI,

I have executed Sleep mode in AM3358 using this command

rtcwake -u 10 -m standby

Though it was able to wake up at the precise time,but the USB was not able to resume its functionality, that is , it is not able to read the data from the host. Could you please suggest the next step ahead?

Thanks

Shiva.

Thanks Liu, for the Information, For the above kernel version there is an issue with the git repository, as it is throwing that version is unavailable. Instead of Kernel patch, is this issue could be resolved by flashing the latest Beagle Bone Debian Image?

Ayla,

Sorry, I didn't realize you used Debian 4.1 kernel. The kernel patch I mentioned above is not applicable to v4.1 kernel, as the bug which the patch is fixing was introduced in v4.16-rc3.

But 1) this forum only supports TI Processor SDK, Debian is not supported, 2) v4.1 kernel is very old and no longer supported. So I recommend you use the latest TI Processor SDK Linux v6.3 and apply the kernel patch I mentioned above. Or if you have to use Debian, please ask the open source community for support.
