Get the latest recovery image jh7110-devkits-recovery-20230918.bin:

Get the latest version of the two files u-boot-spl.bin.normal.out and visionfive2_fw_payload.img:
https://github.com/starfive-tech/VisionFive2/releases/download/JH7110_VF2_515_v5.12.0/u-boot-spl.bin.normal.out

https://github.com/starfive-tech/VisionFive2/releases/download/JH7110_VF2_515_v5.12.0/visionfive2_fw_payload.img

Then follow the instructions here. I found them very clear:

I built U-boot following the instructions on Github and everything seemed to com…pile properly but after flashing it seems it was a bad build. I’m trying to recover the firmware using the instructions on Github and in the quick-start guide (https://doc-en.rvspace.org/VisionFive2/PDF/VisionFive2_QSG.pdf). I have my jumpers set to 1,1, and when I boot the device I get UART output of “CCCCCCCC” (which is what I understand it should be). However, I’m unable to send the recovery firmware file successfully. I have tried two different USB-serial cables, each that seem fine. I have tried using minicom, picocom, and screen to send the file via xmodem, but no luck with anything. Using picocom (my preferred console app), I get the following: ``` CCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCC *** file: jh7110-recovery-20221205.bin $ sx -avO jh7110-recovery-20221205.bin Sending jh7110-recovery-20221205.bin, 1291 blocks: Give your local XMODEM receive command now. Retry 0: NAK on sector Retry 0: NAK on sector Retry 0: NAK on sector Retry 0: NAK on sector Retry 0: NAK on sector Retry 0: NAK on sector Retry 0: NAK on sector Retry 0: NAK on sector Retry 0: NAK on sector Retry 0: NAK on sector Retry 0: NAK on sector Retry 0: Retry Count Exceeded Transfer incomplete *** exit status: 128 *** Error ``` I’ve tried resetting the device with both power and the reset button while transferring, and leaving it as is. I’ve tried with MacOS and with Kali (Kali is a VM, if that makes a difference). Still no luck though. Can someone post step-by-step instructions for what to run software-wise? Everything I’ve seen says “send the file via xmodem” but there are many possibilities of how to do that, so I’d appreciate if someone can tell me how they’ve done it.

OK. I did this on Sunday 9 June 2024.
This worked for me.

PHYSICALLY CHANGE DIP SWITCHES BOTH SET TO HIGH 1
This sets the board in UART FIRMWARE RECOVERY MODE

sudo minicom -b 115200 -D /dev/ttyUSB0

###HELP
ctrl a z
###CONFIG

###file transfer protocols
So all this stuff is ok.
Serial port setup--->>>Software Flow Control--->>>YES
Serial port setup--->>>Hardware Flow Control--->>>NO
Save config

###get the minicom help menu
Ctrl a z
###send file
s
###choose the xmodem protocol
xmodem
###select the file to upload
jh7110-recovery-20230918.bin
press space to tag it
press enter to start the send
NOTE: it will beep to say it sent it successfully then please wait until you get the menu back.  It takes time.

###To send the spl file, we want to use the menu item "Update SPL in FLASH"

ctrl a z
s
xmodem
u-boot-spl.bin.normal.out
press space
press enter to start the send
NOTE: it will beep to say it sent it successfully then please wait until you get the menu back.  It takes time.

###To send the fw payload, we want to use "Update UBOOT in FLASH"

press space
press enter to start the send
NOTE: it will beep to say it sent it successfully then please wait until you get the menu back.  It takes time.

PHYSICALLY CHANGE DIP SWITCHES BOTH SET TO LOW 0
This sets the board in DEFAULT MANUFACTURER BOOT MODE

Done. This worked for me. I hope it works for you too.

After all this however, when I insert any sdcard, any distro, none boot up.
I get this:
