========================================
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
