- ========================================
- Renesas R0P7757LC0030RL board
- ========================================
- This board specification:
- =========================
- The R0P7757LC0030RL(board config name:sh7757lcr) has the following device:
- - SH7757 (SH-4A)
- - DDR3-SDRAM 256MB (with ECC)
- - SPI ROM 8MB
- - 2D Graphic controller
- - Ethernet controller
- - eMMC 2GB
- configuration for This board:
- =============================
- You can select the configuration as follows:
- - make sh7785lcr_config
- This board specific command:
- ============================
- This board has the following its specific command:
- - sh_g200
- - write_mac
- 1. sh_g200
- If we run this command, SH4 can control the G200.
- The default setting is that SH4 cannot control the G200.
- 2. write_mac
- You can write MAC address to SPI ROM.
- Usage 1) Write MAC address
- write_mac [ETHERC ch0] [ETHERC ch1] [GETHERC ch0] [GETHERC ch1]
- For example)
- => write_mac 00:00:87:6c:21:80 00:00:87:6c:21:81 00:00:87:6c:21:82 00:00:87:6c:21:83
- *) 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
- ETHERC ch0 = 00:00:87:6c:21:80
- ETHERC ch1 = 00:00:87:6c:21:81
- GETHERC ch0 = 00:00:87:6c:21:82
- GETHERC ch1 = 00:00:87:6c:21:83
- Update SPI ROM:
- ============================
- 1. Copy u-boot image to RAM area.
- 2. Probe SPI device.
- => sf probe 0
- 8192 KiB M25P64 at 0:0 is now current device
- 3. Erase SPI ROM.
- => sf erase 0 80000
- 4. Write u-boot image to SPI ROM.
- => sf write 0x89000000 0 80000
