Part Number: AM3352
Hi,
In our application, we are using AM335x USB in host mode and sometimes we get babble errors when we
connect the USB device(USB serial). As per the suggestions mentioned in the E2E posts we are restarting the
USB controller in order to recover from the babble error.
Most of the times we are able to recover the USB serial connection after restarting the USB host controller,
but sometimes we are not able to recover the connection.
Looking into the issue we found that after reinitializing host controller, it fails during
transition to host mode (there are no reset signals from D+ to D- pins during this transition).
Could you please let me know what could be the reason for the USB controller to
fail during the transition from USB device mode to Host mode?
PDK version used: pdk_am335x_1_0_9 (processor_sdk_rtos)
Best Regards
paddu
