======================================== Renesas SH7753 EVB board ======================================== This board specification: ========================= The SH7753 EVB (board config name:sh7753evb) has the following device: - SH7753 (SH-4A) - DDR3-SDRAM 512MB - SPI ROM 8MB - Gigabit Ethernet controllers - eMMC 4GB Configuration for This board: ============================= You can select the configuration as follows: - make sh7753evb_config 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
