- Starfive VisionFive2
- ====================
- The VisionFive2 is a low-cost RISC-V 64-bit based platform, powered by a
- Starfive JH7110 processor.
- https://doc-en.rvspace.org/Doc_Center/visionfive_2.html
- 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:
- https://doc-en.rvspace.org/VisionFive2/Quick_Start_Guide/VisionFive2_SDK_QSG/recovering_bootloader%20-%20vf2.html
- 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.
- https://doc-en.rvspace.org/VisionFive2/Quick_Start_Guide/VisionFive2_SDK_QSG/boot_mode_settings.html
- Insert your SD card.
- Power-up the board using an USB-C cable.
