| Luka Kovacic | 25acb8b | 2020-05-26 20:17:50 +0200 | [diff] [blame] | 4 | CRS3XX-98DX3236 is a U-Boot port that supports a series of MikroTik switches |
| 5 | based on the Marvell Prestera 98DX3236 switch with an integrated CPU. |
| 6 | |
| 7 | Common specifications: |
| Luka Kovacic | b686e22 | 2019-05-07 19:35:55 +0200 | [diff] [blame] | 8 | - Marvell Prestera 98DX3236 switch with an integrated ARMv7 CPU |
| 9 | - 512 MB DDR3 RAM |
| 10 | - UART @ 115200bps |
| Luka Kovacic | b686e22 | 2019-05-07 19:35:55 +0200 | [diff] [blame] | 11 | - 16 MB SPI flash (Winbond 25Q128JVSM) |
| 12 | |
| 13 | Currently supported hardware: |
| 14 | - UART boot (using kwboot) and console |
| 15 | - SPI boot, environment and load kernel |
| 16 | |
| 17 | Planned: |
| Luka Kovacic | 25acb8b | 2020-05-26 20:17:50 +0200 | [diff] [blame] | 18 | - Gigabit Ethernet support (internal CPU <-> switch fabric connection) |

| 20 | Getting binary.0 |
| 21 | ================ |
| 22 | binary.0 (DDR3 init phase) can be retrieved/extracted from the integrated bootloader on the SPI flash. |
| 23 | Then binary.0 can be replaced with the extracted blob. |
