The source / destination address of the SDHC transfer needs to be
word-aligned.
Use the mtd buffer to fix the alignment if `mtd_write_page` is used,
otherwise return -ENOTSUP.
The assertion is a bit overeager.
In case of receiving a wrong message ID, we re-try receive without
entering the STATE_REQUEST_SEND state again, so it is expected that
we get a non-NULL ctx/response from sock_udp_recv_buf().
What this assert should actually check is that we don't get a non-NULL
ctx after calling sock_udp_recv_buf() with a non-NULL ctx.
So make this explicit to not falsely fail the assertion.
An network devices that supports netdev_driver_t::get(NETOPT_LINK, ...)
also has to emit NETDEV_EVENT_LINK_UP and NETDEV_EVENT_LINK_DOWN with
lwip for IPv6 duplicate address detection to work. The background is
that the STM32 Ethernet MAC requires a periodic timer to poll for the
state to emit these events. For this reason, `stm32_eth_link_up` was
introduced to allow applications to select if they need these events.
With this dependency in place, IPv6 addresses won't get stuck in a
tentative state any more.
This better reflects the current state of things. Setting the nightly
toolchain as default works better for new users with the current
settings of the examples. Not pinning the C2Rust version -- we don't pin
the nightly version in the docs either, and breakage is easy to track
given the container builds as a base line.
detect_includes_and_version_gcc() previously only detected the includes,
but has been extended to also return the version. This is done by
returning a tuple, with the first item being the list of include paths,
and the second being the version. In the error handling the script still
returns only an empty list of includes, but not an empty version. This
fixes the issue.
This removes the existing hack, in which we wrote the configuration to
/dev/null to trigger its evaluation. Instead a function for this
specific purpose is added.
- The `periph_flashpage` driver expects the manual write bit to be set
This should be set by default, but the SAM D20/SAM D21 errata sheets
correct that this is indeed *not* set by default, which may cause
spurious writes.
- SAM D20 may not wake up from any sleep mode if sleep power reduction
is enabled for the NVM block.
In a881af8b08f39 we would return early if the subnet did not change,
but we must still send the router advertisement with the route information
option to the upstream network, otherwise hosts in that network will not
consider the downstream subnet off-link.
We can't use PB13/PB12 which would be the 'standard' UART pins on
the -xpro EXT connectors since only SERCOM4 can map to those - and
that's already used on EXT1.
So use the adjacent PA08/PA09 with SERCOM0.
