1 | m1nor - Flash a file to M1 NOR partition selected by the file name | |
2 | ================================================================== | |
3 | ||
4 | During software development, one often need to update only the | |
5 | content of a single partition. reflash_m1.sh is a bit unwieldy | |
6 | for this kind of task. | |
7 | ||
8 | I've written a small script called m1nor that selects the target | |
9 | partition based on the file name. E.g., m1nor flickernoise.fbi | |
10 | would update the regular Flickernoise partition. | |
11 | ||
12 | The matching algorithm checks the beginning of the file name, | |
13 | so names like flickernoise-test.fbi would also work. Furthermore, | |
14 | it checks the file extension, so if you try to flash flickernoise | |
15 | (ELF, for debugging) or flickernoise.bin (an intermediate form | |
16 | unsuitable for booting from NOR), it will politely refuse to do | |
17 | so. | |
18 | ||
19 | You need to have fjmem.bit somwehere. It searches for it under | |
20 | $HOME/.qi/milkymist/, where reflash_m1.sh caches it. You can also | |
21 | specify the location directly by setting the environment variable | |
22 | FJMEM_BIT. |
