The kernel driver will now ask for ATUSB_EUI64_READ during init and sets this
extended address if available. Use the atusb-eui64 utility from the tools folder
to read or set the permanent address.
After a new address is set the device will reset to make sure we are in a sane
state after the change.
With version 0.2 we made the first public release in binary form of the
firmware. This comes together with the merge of the ATUSB driver to the
mainline linux kernel.
At an interrupt barrier, the host must be able to ensure that no
interrupt generated before reaching the barrier is still pending and
will be delivered after crossing the barrier.
For this, we introduce the following concept:
- interrupts have a serial number. This number is sent to the host
on EP 1 (currently bulk) to signal the interrupt, instead of the
zero byte we used previously.
- the new request ATUSB_SPI_WRITE2_SYNC returns the interrupt
serial number from after the register write (the register write
itself is the interrupt barrier).
- the host can now check if the serial indicated from bulk and the
serial from ATUSB_SPI_WRITE2_SYNC are the same. If yes, interrupts
are synchronized. If not, it has to wait for the interrupt to be
signaled on EP 1.
We should also consider the case that the interrupt serial has gotten
ahead of ATUSB_SPI_WRITE2_SYNC. But that seems to happen rarely. In
any case, it's something for the host driver to worry about, not for
the firmware.
- board.h (irq_serial), board_app.c (irq_serial, INT0_vect): count
the interrupt serial number and return it when signaling the
interrupt
- include/atusb/ep0.h (ATUSB_SPI_WRITE2_SYNC), ep0.c (my_setup):
new request ATUSB_SPI_WRITE2_SYNC that does a register write, then
returns the interrupt serial
This reverts commit 39e3d4e61a.
The log isn't so useful in its present state because we may have to
unplug/replug to get out of a troublesome condition.

when done manipulating GPIOs
