| 2 | --------------------------- |
| 3 | |
| 4 | Musenki M-1 and M-3 have two banks of flash of 4MB or 8MB each. |
| 5 | |
| 6 | In board's notation, bank 0 is the one at the address of 0xFF800000 |
| 7 | and bank 1 is the one at the address of 0xFF000000. |
| 8 | |
| 9 | On power-up the processor jumps to the address of 0xFFF00100, the last |
| 10 | megabyte of the bank 0 of flash. |
| 11 | |
| 12 | Thus, U-Boot is configured to reside in flash starting at the address of |
| 13 | 0xFFF00000. The environment space is located in flash separately from |
| 14 | U-Boot, at the address of 0xFF800000. |
| 15 | |
| 16 | There is a Davicom 9102A on-board, but I don't have it working yet. |
