| 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. |
