>Different revisions of the SA11x0 silicon have had various problems
|
| 126 |
|
|
with the USB support. The device driver has been tested primarily
|
| 127 |
|
|
against stepping B4 of the SA1110 processor, and may not function as
|
| 128 |
|
|
expected with other revisions. Application developers should obtain
|
| 129 |
|
|
the manufacturer's current errata sheets and specification updates.
|
| 130 |
|
|
The B4 stepping still has a number of problems, but the device driver
|
| 131 |
|
|
can work around these. However there is a penalty in terms of extra
|
| 132 |
|
|
code, extra cpu cycles, and increased dispatch latency because extra
|
| 133 |
|
|
processing is needed at DSR level. Interrupt latency should not be
|
| 134 |
|
|
affected.</P
|
| 135 |
|
|
><P
|
| 136 |
|
|
>There is one specific problem inherent in the UDC design of which
|
| 137 |
|
|
application developers should be aware: the hardware cannot fully
|
| 138 |
|
|
implement the USB standard for bulk transfers. A bulk transfer
|
| 139 |
|
|
typically consists of some number of full-size 64-byte packets and is
|
| 140 |
|
|
terminated by a packet less than the full size. If the amount of data
|
| 141 |
|
|
transferred is an exact multiple of 64 bytes then this requires a
|
| 142 |
|
|
terminating packet of 0 bytes of data (plus header and checksum). The
|
| 143 |
|
|
SA11x0 USB hardware does not allow a 0-byte packet to be transmitted,
|
| 144 |
|
|
so the device driver is forced to substitute a 1-byte packet and the
|
| 145 |
|
|
host receives more data than expected. Protocol support is needed so
|
| 146 |
|
|
that the appropriate host-side device driver can allow buffer space
|
| 147 |
|
|
for the extra byte, detect when it gets sent, and discard it.
|
| 148 |
|
|
Consequently certain standard USB class protocols cannot be
|
| 149 |
|
|
implemented using the SA11x0, and therefore custom host-side device
|
| 150 |
|
|
drivers will generally have to be provided, rather than re-using
|
| 151 |
|
|
existing ones that understand the standard protocol.</P

>The SA11X0 UDC provides only limited fifos for bulk transfers on
|
| 362 |
|
|
endpoints 1 and 2; smaller than the normal 64-byte bulk packet size.
|
| 363 |
|
|
Therefore a typical transfer requires the use of DMA engines. The
|
| 364 |
|
|
SA11x0 provides six DMA engines that can be used for this, and the
|
| 365 |
|
|
endpoints require one each (assuming both endpoints are enabled). At
|
| 366 |
|
|
the time of writing there is no arbitration mechanism to control
|
| 367 |
|
|
access to the DMA engines. By default the device driver will use
|
| 368 |
|
|
DMA engine 4 for endpoint 1 and DMA engine 5 for endpoint 2, and it
|
| 369 |
|
|
assumes that no other code uses these particular engines.</P

|
| 381 |
|
|
options have the booldata flavor, allowing the use of DMA to be
|
| 382 |
|
|
disabled completely in addition to controlling which DMA engines are
|
| 383 |
|
|
used. If DMA is disabled then the device driver will attempt to
|
| 384 |
|
|
work purely using the fifos, and the packet size will be limited to
|
| 385 |
|
|
only 16 bytes. This limit should be reflected in the appropriate
|
| 386 |
|
|
endpoint descriptors in the enumeration data. The code for driving the
|
| 387 |
|
|
endpoints without DMA should be considered experimental. At best it
|
| 388 |
|
|
will be suitable only for applications where the amount of data
|
| 389 |
|
|
transferred is relatively small, because four times as many interrupts
|
| 390 |
|
|
will be raised and performance will suffer accordingly.</P
