| 2 | Renesas SH7753 EVB board |
| 3 | ======================================== |
| 4 | |
| 5 | This board specification: |
| 6 | ========================= |
| 7 | |
| 8 | The SH7753 EVB (board config name:sh7753evb) has the following device: |
| 9 | |
| 10 | - SH7753 (SH-4A) |
| 11 | - DDR3-SDRAM 512MB |
| 12 | - SPI ROM 8MB |
| 13 | - Gigabit Ethernet controllers |
| 14 | - eMMC 4GB |
| 15 | |
| 16 | |
| 17 | Configuration for This board: |
| 18 | ============================= |
| 19 | |
| 20 | You can select the configuration as follows: |
| 21 | |
| 22 | - make sh7753evb_config |
| 23 | |
| 24 | |
| 25 | This board specific command: |
| 26 | ============================ |
| 27 | |
| 28 | This board has the following its specific command: |
| 29 | |
| 30 | - write_mac |
| 31 | |
| 32 | |
| 33 | 1. write_mac |
| 34 | |
| 35 | You can write MAC address to SPI ROM. |
| 36 | |
| 37 | Usage 1) Write MAC address |
| 38 | |
| 39 | write_mac [GETHERC ch0] [GETHERC ch1] |
| 40 | |
| 41 | For example) |
| 42 | => write_mac 74:90:50:00:33:9e 74:90:50:00:33:9f |
| 43 | *) We have to input the command as a single line |
| 44 | (without carriage return) |
| 45 | *) We have to reset after input the command. |
| 46 | |
| 47 | Usage 2) Show current data |
| 48 | |
| 49 | write_mac |
| 50 | |
| 51 | For example) |
| 52 | => write_mac |
| 53 | GETHERC ch0 = 74:90:50:00:33:9e |
| 54 | GETHERC ch1 = 74:90:50:00:33:9f |
| 55 | |
| 56 | |
| 57 | Update SPI ROM: |
| 58 | ============================ |
| 59 | |
| 60 | 1. Copy u-boot image to RAM area. |
| 61 | 2. Probe SPI device. |
| 62 | => sf probe 0 |
| 63 | SF: Detected MX25L6405D with page size 64KiB, total 8 MiB |
| 64 | 3. Erase SPI ROM. |
| 65 | => sf erase 0 80000 |
| 66 | 4. Write u-boot image to SPI ROM. |
| 67 | => sf write 0x48000000 0 80000 |
