| 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 | |
| Filename 'u-boot.bin'. | |
| Load address: 0x40000000 | |
| Loading: ############ | |
| 2.5 MiB/s | |
| done | |
| Bytes transferred = 175364 (2ad04 hex) | |
| #2, Commands to erase/write u-boot to flash device | |
| Note: This method is description of the lager board. If you want to use the | |
| other boards, please change the value according to each environment. | |
| => sf probe 0 | |
| SF: Detected S25FL512S_256K with page size 512 Bytes, erase size 64 KiB, total 64 MiB | |
| => sf erase 80000 40000 | |
| SF: 262144 bytes @ 0x80000 Erased: OK | |
| => sf write 40000000 80000 175364 | |
| SF: 1528676 bytes @ 0x80000 Written: OK | |
| => | |
| #3, Push reset button. | |
| If you're written correctly and driver works properly, U-Boot starts. |
