| 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. | |
