fix(st): replace down counter by a timeout upon dfu detach
On stm32mp2, DFU detach sometimes makes subsequent usb start to fail.
The core doesn't have the time to properly finalize the last setup
phase. This results in error logs seen:
ERROR: dwc3_handle_dev_event: 1688
ERROR: dwc3_handle_dev_event: 1692
Just enabling "DFU USB STOP" message hides the issue, sequentially:
usb_core_start()
...
usb_dfu_loop() // runs until DFU_DETACH command
--> while(it_count != 0U) {
usb_core_handle_it()
if (usb_dfu_detach_req)
it_count--; // down count from 100 to 0
}
...
INFO("DFU USB STOP...\n");
usb_core_stop()
The down-counter (it_count) value doesn't seem to be enough, and seems
not robust against CPU speed. So rather adopt a 100us timeout. It's
determined experimentally (above issue seems to be triggered around
20us to 30us, so keep some margin).
