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 |
