Urprotocol is a leaner version of the STK500 1.x protocol that is designed
to be backwards compatible with STK500 v1.x; it allows bootloaders to be
much smaller, eg, as implemented in the urboot project
@uref{https://github.com/stefanrueger/urboot}. The programmer type ``urclock''
caters for these urboot programmers. Owing to its backward compatibility,
bootloaders that can be served by the arduino programmer can normally
also be served by the urclock programmer.

@item Urclock
The urclock programmer type accepts the following extended parameters:
@table @code
@item @samp{showall}
Show all info for the connected part, then exit. The @code{-xshow...} options
below can be used to assemble a bespoke response consisting of a subset
(or only one item) of all available relevant information about the
connected part and bootloader.
@item @samp{showid}
Show a unique Urclock ID stored in either flash or EEPROM of the MCU, then exit.
@item @samp{id=<E|F>.<addr>.<len>}
Historically, the Urclock ID was a six-byte unique little-endian number
stored in Urclock boards at EEPROM address 257. The location of this
number can be set by the @code{-xid=<E|F>.<addr>.<len>} extended parameter. @code{E}
stands for EEPROM and @code{F} stands for flash. A negative address addr counts
from the end of EEPROM and flash, respectively. The length len of the
Urclock ID can be between 1 and 8 bytes.
@item @samp{showdate}
Show the last-modified date of the input file for the flash application,
then exit. If the input file was stdin, the date will be that of the
programming. Date and filename are part of the metadata that the urclock
programmer stores by default in high flash just under the bootloader; see also
@code{-xnometadata}.
@item @samp{showfilename}
Show the input filename (or title) of the last flash writing session, then exit.
@item @samp{title=<string>}
When set, <string> will be used in lieu of the input filename. The maximum
string length for the title/filename field is 254 bytes including
terminating nul.
@item @samp{showapp}
Show the size of the programmed application, then exit.
@item @samp{showstore}
Show the size of the unused flash between the application and metadata, then exit.
@item @samp{showmeta}
Show the size of the metadata just below the bootloader, then exit.
@item @samp{showboot}
Show the size of the bootloader, then exit.
@item @samp{showversion}
Show bootloader version and capabilities, then exit.
@item @samp{showvector}
Show the vector number and name of the interrupt table vector used by the
bootloader for starting the application, then exit. For hardware-supported
bootloaders this will be vector 0 (Reset), and for vector bootloaders this
will be any other vector number of the interrupt vector table or the slot
just behind the vector table with the name @code{VBL_ADDITIONAL_VECTOR}.
@item @samp{showpart}
Show the part for which the bootloader was compiled, then exit.
@item @samp{bootsize=<size>}
Manual override for bootloader size. Urboot bootloaders put the number of
used bootloader pages into a table at the top of the bootloader section,
ie, typically top of flash, so the urclock programmer can look up the
bootloader size itself. In backward-compatibility mode, when programming
via other bootloaders, this option can be used to tell the programmer the
size, and therefore the location, of the bootloader.
@item @samp{vectornum=<arg>}
Manual override for vector number. Urboot bootloaders put the vector
number used by a vector bootloader into a table at the top of flash, so
this option is normally not needed for urboot bootloaders. However, it is
useful in backward-compatibility mode (or when the urboot bootloader does
not offer flash read). Specifying a vector number in these circumstances
implies a vector bootloader whilst the default assumption would be a
hardware-supported bootloader.
@item @samp{eepromrw}
Manual override for asserting EEPROM read/write capability. Not normally
needed for urboot bootloaders, but useful for in backward-compatibility
mode if the bootloader offers EEPROM read/write.
@item @samp{emulate_ce}
If an urboot bootloader does not offer a chip erase command it will tell
the urclock programmer so during handshake. In this case the urclock
programmer emulates a chip erase, if warranted by user command line
options, by filling the remainder of unused flash below the bootloader
with 0xff. If this option is specified, the urclock programmer will assume
that the bootloader cannot erase the chip itself. The option is useful
for backwards-compatible bootloaders that do not implement chip erase.
@item @samp{restore}
Upload unchanged flash input files and trim below the bootloader if
needed. This is most useful when one has a backup of the full flash and
wants to play that back onto the device. No metadata are written in this
case and no vector patching happens either if it is a vector bootloader.
However, for vector bootloaders, even under the option @code{-xrestore} an
input file will not be uploaded for which the reset vector does not point
to the vector bootloader. This is to avoid writing an input file to the
device that would render the vector bootloader not functional as it would
not be reached after reset.
@item @samp{initstore}
On writing to flash fill the store space between the flash application and
the metadata section with 0xff.
@item @samp{nofilename}
On writing to flash do not store the application input filename (nor a title).
@item @samp{nodate}
On writing to flash do not store the application input filename (nor a
title) and no date either.
@item @samp{nometadata}
On writing to flash do not store any metadata. The full flash below the
bootloader is available for the application. In particular, no data store
frame is programmed.
@item @samp{delay=<n>}
Add a <n> ms delay after reset. This can be useful if a board takes a
particularly long time to exit from external reset. <n> can be negative,
in which case the default 110-140 ms delay after issuing reset will be
shortened accordingly.
@item @samp{strict}
Urclock has a faster, but slightly different strategy than -c arduino to
synchronise with the bootloader; some stk500v1 bootloaders cannot cope
with this, and they need the @code{-xstrict} option.
@item @samp{help}
Show this help menu and exit

* one byte Sync_CRC_EOP (because the first byte is overwritten) getting the communication out
* of step through a missing byte. If AVRDUDE then sends the next request starting with a
* Cmnd_STK_GET_SYNC command then optiboot v4.4 will bail as ist's not Sync_CRC_EOP. Hence, the
* strategy here is to send Sync_CRC_EOP/Sync_CRC_EOP for getting a sync. For those bootloaders
* that are strict about the protocol, eg, picoboot, the presence of -xstrict implies that
* comms should use Cmnd_STK_GET_SYNC for getting in sync.
