Simple steps used to test the SH-QSPI at U-Boot
|
||
|
|
-------------------------------------------------
|
||
|
|
|
||
|
|
#0, Currently, SH-QSPI is used by lager board (Renesas ARM SoC R8A7790)
|
||
|
|
and koelsch board (Renesas ARM SoC R8A7791). These boot from SPI ROM
|
||
|
|
basically. Thus, U-Boot start, SH-QSPI will is operating normally.
|
||
|
|
|
||
|
|
#1, build U-Boot and load u-boot.bin
|
||
|
|
|
||
|
|
=> tftpboot 40000000 u-boot.bin
|
||
|
|
sh_eth Waiting for PHY auto negotiation to complete.. done
|
||
|
|
sh_eth: 100Base/Half
|
||
|
|
Using sh_eth device
|
||
|
|
TFTP from server 192.168.169.1; our IP address is 192.168.169.79

#2, Commands to erase/write u-boot to flash device

|
|
other boards, please change the value according to each environment.

If you're written correctly and driver works properly, U-Boot starts.
