m1nor - Flash a file to M1 NOR partition selected by the file name
|
|
==================================================================
|
|
|
|
During software development, one often need to update only the
|
|
content of a single partition. reflash_m1.sh is a bit unwieldy
|
|
for this kind of task.
|
|
|
|
I've written a small script called m1nor that selects the target
|
|
partition based on the file name. E.g., m1nor flickernoise.fbi
|
|
would update the regular Flickernoise partition.
|
|
|
|
The matching algorithm checks the beginning of the file name,
|
|
so names like flickernoise-test.fbi would also work. Furthermore,
|
|
it checks the file extension, so if you try to flash flickernoise
|
|
(ELF, for debugging) or flickernoise.bin (an intermediate form
|
|
unsuitable for booting from NOR), it will politely refuse to do
|
|
so.
|
|
|
|
You need to have fjmem.bit somwehere. It searches for it under
|
|
$HOME/.qi/milkymist/, where reflash_m1.sh caches it. You can also
|
|
specify the location directly by setting the environment variable
|
|
FJMEM_BIT.

xdltap - Route nets from inside the FPGA to I/O pads
|
|
====================================================
|
|
|
|
xdltap adds routes from signals inside the FPGA to I/O pads. It
|
|
does this by converting the .ncd file generated by synthesis
|
|
|
|
xdltap signal=output ... [xdl-file]
|
|
|
|
The path to the signal to be tapped has to be fully qualified.
|
|
Note that not all signals are listed in the .pcf file. Some may
|
|
only show up in .xdl
|
|
|
|
The output is the name of a global net that has to be connected
|
|
to an input (!) pad.
|
|
|
|
Signal names containing < and > can be written with { and }, to
|
|
avoid extra escaping for the shell.
|
|
|
|
Since xdl chokes on its own .xdl files, xdlfixes applies a number
|
|
of ugly hacks to either avoid errors or to propagate them to a
|
|
later stage, where they can be ignored.
|
|
|
|
Example:
|
|
|
|
map ... foo.ngd # generates foo.ncd
|
|
xdl -ncd2xdl foo.ncd # generates foo.xdl
|
|
xdltap usb/sie/rx_pending=exp{8} foo.xdl | xdlfixes >foo-dbg.xdl
|
|
xdl -xdl2ncd foo-dbg.xdl # generates foo-dbg.ncd
|
|
par ... foo-dbg.ncd ...
