| 2 | Simple steps used to test the SH-QSPI at U-Boot |
| 3 | ------------------------------------------------- |
| 4 | |
| 5 | #0, Currently, SH-QSPI is used by lager board (Renesas ARM SoC R8A7790) |
| 6 | and koelsch board (Renesas ARM SoC R8A7791). These boot from SPI ROM |
| 7 | basically. Thus, U-Boot start, SH-QSPI will is operating normally. |
| 8 | |
| 9 | #1, build U-Boot and load u-boot.bin |
| 10 | |
| 11 | => tftpboot 40000000 u-boot.bin |
| 12 | sh_eth Waiting for PHY auto negotiation to complete.. done |
| 13 | sh_eth: 100Base/Half |
| 14 | Using sh_eth device |
| 15 | TFTP from server 192.168.169.1; our IP address is 192.168.169.79 |
| 16 | Filename 'u-boot.bin'. |
| 17 | Load address: 0x40000000 |
| 18 | Loading: ############ |
| 19 | 2.5 MiB/s |
| 20 | done |
| 21 | Bytes transferred = 175364 (2ad04 hex) |
| 22 | |
| 23 | #2, Commands to erase/write u-boot to flash device |
| 24 | |
| 25 | Note: This method is description of the lager board. If you want to use the |
| 26 | other boards, please change the value according to each environment. |
| 27 | |
| 28 | => sf probe 0 |
| 29 | SF: Detected S25FL512S_256K with page size 512 Bytes, erase size 64 KiB, total 64 MiB |
| 30 | => sf erase 80000 40000 |
| 31 | SF: 262144 bytes @ 0x80000 Erased: OK |
| 32 | => sf write 40000000 80000 175364 |
| 33 | SF: 1528676 bytes @ 0x80000 Written: OK |
| 34 | => |
| 35 | |
| 36 | #3, Push reset button. |
| 37 | |
| 38 | If you're written correctly and driver works properly, U-Boot starts. |
