| Starfive VisionFive2 |
| ==================== |
| |
| The VisionFive2 is a low-cost RISC-V 64-bit based platform, powered by a |
| Starfive JH7110 processor. |

| |
| How to build |
| ============ |
| |
| $ make visionfive2_defconfig |
| $ make |
| |
| Once the build process is finished you will have two images |
| in the output/images/ directory: |
| - sdcard.img |
| - spi-nor.img |
| |
| How to write the SPI NOR flash |
| ============================= |
| |
| If you have a booting device use u-boot and tftp: |
| |
| # tftpboot 0x82000000 spi-nor.img |
| # sf probe |
| # sf update 0x82000000 0x0 {filesize} |
| |
| Otherwise, follow the recovery instruction: |

| |
| How to write the SD card |
| ======================== |
| |
| Copy the bootable "sdcard.img" onto an SD card with "dd": |
| |
| $ sudo dd if=output/images/sdcard.img of=/dev/sdX |
| |
| Preparing the board |
| =================== |
| |
| Connect a TTL UART cable to pin 6 (GND), 8 (TX) and 10 (RX). |
| |
| Use the correct mode for booting: |
| - SD card RGPIO_0=1, GRPIO_1=0 |
| - SPI NOR flash RGPIO_0=1, GRPIO_1=1 |
| |
| Note that Buildroot puts the bootloader both in SPI NOR and on the SD card, |
| so after flashing as instructed above, either boot mode should work. |

| |
| Insert your SD card. |
| |
| Power-up the board using an USB-C cable. |
