Firmware update to SPI flash

Select the boot mode switch to RGPIO_0 = 0'b, RGPIO_1 = 0'b.
Copy u-boot-spl.bin.normal.out and visionfive2_fw_payload.img to your tftp server.
set the u-boot IP and the tftp server IP, for example:

setenv ipaddr 192.168.120.222; setenv serverip 192.168.120.99

Run the following u-boot commands:

#SPI flash probe
sf probe
# Download and flash the u-boot SPL
tftpboot 0xa0000000 ${serverip}:u-boot-spl.bin.normal.out
sf update 0xa0000000 0x0 $filesize
# Download and flash opensbi+u-boot-payload
tftpboot 0xa0000000 ${serverip}:visionfive2_fw_payload.img
sf update 0xa0000000 0x100000 $filesize
