When dcd_edpt_xfer() starts new transfer two separate problems were observed.
For both problems stream of OUT packets was pouring from host.
First problem was that total_len and actual_len were not atomic.
In case where incoming OUT packets are less (63) than MPS (64), actual_len and total_len
are set 63.
Then transfer complete from USBD is called that will schedule next 64 bytes transfer.
At that point incoming packet would start DMA if there is place in RAM, normally
it does not happen since actual_len == total_len.
If packets arrives and interrupt is raised after total_len is set (64) but actual_len is still 63 from
previous transfer, interrupt code sees that there is place in ram (1 byte) and transfer this 1 byte
to buffer that was already filled with previous packet.
To remedy this USB interrupt is blocked during transfer setup.
Second problem can happen when dcd_edpt_xfer setups xfer->total_len and actual_len correctly
but then context switch happens before xfer->data_received is checked.
If during this time two packets arrive one will be copied to RAM second will stay in endpoint with
data_received set to 1.
Then when xfer_edpt_xfer() checks data_receive flag it starts DMA again overwriting data.
To remedy this, data_received is checked together with check if data was already transferred.
If transfer was complete, there is no need to start DMA yet.
In such case data_received will be handled in same place by next xfer_edpt_xfer() correctly.

These are different Broadcom chips. The peripherals are essentially
the same. The main differences are:
* The CPU(s)
* The interrupt controller
* The peripheral base address (but not the peripherals that we use)

definition of DEBUG breaks Microchip pic32 builds for Mynewt.
When MCU is not VALENTYUSB_EPTRI there is no need to have any
preprocessor definitions.
It may not look like a big deal but for xc32 builds, compiler
automatically force-includes some file that have structure with field name
DEBUG that result in build error in dcd_eptri.c when this file
is not really needed.
Moving DEBUG and LOG_USB few lines down should not break eptri builds.

nrf5x: Fix race condition during startup
|
|
|
|
When NRF5x device is reset by software (after DFU for example),
power event is ready from the beginning.
When power interrupt is triggered before tud_init() finished
USBD_IRQn is enabled before it would be enabled in tud_init().
This in turn may result in BUS RESET event being sent from
USB interrupt to USB task when queue is not initialized yet.
This scenario often happens in Mynewt build where queue creation
takes more time.
To prevent this scenario USBD_IRQn is not enabled in power event
interrupt handler before dcd_init() was called.

Fix invalid assert in RP2040 host mode when compiled in debug mode

Bluetooth's specification defines IAD for primary controller.
While it seems that Windows and Linux can leave without this,
there is no reason TinyUSB should not provide it.
|
|
Two interfaces that are required by Bluetooth Primary Controller
do not have IAD according to Bluetooth specification.
Those two interfaces were opened separately in process_set_config().
Later interface association was inferred for BTH (along with other
drivers), since then only one call to open() is place for BTH driver
that should prepare both interfaces at once.
To make it work again btd_open() parses two interfaces at once.

for ep->active should only happen if a setup packet was just sent. Otherwise the transaction is handled in hw_handle_buff_status.

dcd_synopsys.c included broadcom/interrupts.h before
preprocessor check whether file should be used.
Since mynewt build does not include all folders it resulted in build
error.
Now offending include is moved few lines after preprocessor check.
