USB Failure - VL805 FW version: 00000000 - Can't flash EEPROM

Sat Jun 06, 2020 11:22 am

Hello
Like other on this board I've got a problem with my raspberry pi 4 4G.
I tried all tricks I find but I can't recover the vl805 firmware on the eeprom...
Still got my VL805 firmware version at 00000000
Does anyone got a solution ?
Thanks

So creating a recovery SD card using rpi imager doesn't work?

Does it boot at all, if so run

sudo apt update
sudo apt full-upgrade

Minor note (not the root of your problem, nor a fix), when running as root, sudo is superfluous.

Hi
Yes with a sd card prepared in headless mode with raspbian lite and ssh activate, I can putty my raspberry, do all apt update & full-upgrade and rpi-eeprom-update -d -f and -u but when I reboot, the raspberry is stuck, just one green led flash and nothing (I saw that the rpi-eeprom-update create the recovery.bin file and when there is the recovery.bin in the raspberry, it doesn't boot at all)
Thanks

I don't think you need the rip eeprom stuff, apt now handles the bootloader updates. Is that what breaks booting?

Sorry, but I don't really understand your answer.

What I see is that Iv' got current FW version for my Raspberry VL805 to 00000000 and that my usb port doesn't work at all !
So, if you've got a solution to correct that, I will be very glad

Thanks

Use a recovery SD card to reflash both the bootloader and VLI eeprom.

Hi
I tried this procédure but when I boot with the recovery sd card the green led flash once when I plug the power and nothing more even after 5mn
Thanks

This and other recovery methods don't seem to work in these cases. Since the VL805 firmware is now included in the pieeprom.bin, why not use it if the version is 00000000 in the dedicated VLI EEPROM?

If they don't work then it's likely a HW problem. There should be no mechanism by which they don't work, except a HW failure of some sort.

Of course, there may be a bug, but difficult to see how there can be a bug that affects a tiny proportion of devices, since all the devices are the same. However, It'll be flagged up to check.

If you see zero for the VL805 FW version then that does not mean that the SPI flash is empty or corrupted. It just means that that VL805 firmware is not running for some unknown reason. Maybe a hardware or power supply issue.

You can try using the Raspberry Pi Imager to flash either the latest version or the USB beta version. If you get a green screen on HDMI then the image has flashed correctly.

Revocery mode doesn't work at all
One flash of the green led and nothing else

try using `uart_2ndstage=1` in `config.txt` when you boot `recovery.bin`

then hook a uart adapter up, and see what output it generates
