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.
