| |
| |
| This board specific command: |
| ============================ |
| |
| This board has the following its specific command: |
| |
| - write_mac |
| |
| |
| 1. write_mac |
| |
| You can write MAC address to SPI ROM. |
| |
| Usage 1) Write MAC address |
| |
| write_mac [GETHERC ch0] [GETHERC ch1] |
| |
| For example) |
| => write_mac 74:90:50:00:33:9e 74:90:50:00:33:9f |
| *) We have to input the command as a single line |
| (without carriage return) |
| *) We have to reset after input the command. |
| |
| Usage 2) Show current data |
| |
| write_mac |
| |
| For example) |
| => write_mac |
| GETHERC ch0 = 74:90:50:00:33:9e |
| GETHERC ch1 = 74:90:50:00:33:9f |
| |
| |
| Update SPI ROM: |
| ============================ |
| |
| 1. Copy u-boot image to RAM area. |
| 2. Probe SPI device. |
| => sf probe 0 |
| SF: Detected MX25L6405D with page size 64KiB, total 8 MiB |
| 3. Erase SPI ROM. |
| => sf erase 0 80000 |
| 4. Write u-boot image to SPI ROM. |
| => sf write 0x48000000 0 80000 |
