|
|
|
|
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
|
|
|
|
|
|
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
