========================================
|
||||
Renesas R0P7752C00000RZ board
|
||||
========================================
|
||||
|
||||
This board specification:
|
||||
=========================
|
||||
|
||||
The R0P7752C00000RZ(board config name:sh7752evb) has the following device:
|
||||
|
||||
- SH7752 (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 sh7752evb_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
