(of course with appropriate mounting and unmounting). I all not sure
|
||||
of this and need to do more testing to characterize if the issue.

5. There is not yet any support for the following board features: QSPI, USB,
|
||||
EMAC, AT24, or WM8904 nor for any non-board features). Most of these
|
||||
drivers will port easily from either the SAM3/4 or from the SAMA5Dx.

Many drivers will port easily from either the SAM3/4 or from the SAMA5Dx.
|

So there is still plenty to be done.
|

|

6. There has been a quick'n'dirty port of the SAMA5D4-EK Ethernet logic
|
||||
for the SAMV71-XULT. There are still some cache-related issues to
|
||||
be verified. No testing has yet been performed and so the driver should
|
||||
be considered non-functional.
|
||||
for the SAMV71-XULT. It does not work properly. Data on the line
|
||||
appears to be corrupted, probably at the level of the PHY.
|
||||
|
||||
7. The USBHS device controller driver (DCD) is complete but non-functional.
|
||||
At this point, work has stopped because I am stuck. The problem is that
|
||||
bus events are not occurring: Nothing is detected by the USBHS when the
|
||||
host is connected; no activity is seen on the bus by a USB analyzer when
|
||||
the host is connected. Possibilities: (1) the pullups on DM and DP are
|
||||
not working. This would prevent the host from detecting the presence of
|
||||
the device. the DETACH bit is, however, being correctly cleared or (2)
|
||||
some issue with clocking or configuration of the UTMI. I see nothing
|
||||
wrong this this case. I have done extensive comparison of the Atmel
|
||||
sample code and study of the data sheet, but I have not found the key to
|
||||
solving this.

Stack sizes are also large to simplify the bring-up and should be

tuned for better memory usages.
