I found and added the ESWIN ECR6600U firmware to our kernel package: CI | Add ESWIN ECR6600U USB WiFi adapter firmware · MichaIng/linux@eaf275b · GitHub
If this works, I’ll at least try to enable 5 GHz support with the config key you found.
EDIT: 5 GHz does not work: ECR6600U firmware

Also bumped to Linux 5.15.104.

To update the kernel:

cd /tmp
curl -O 'https://dietpi.com/downloads/binaries/linux-image-visionfive2.deb'
dpkg -i linux-image-visionfive2.deb
rm linux-image-visionfive2.deb

I also tested the fixed U-Boot env QSPI address and it works fine now:

apt install libubootenv-tool
echo '/dev/mtd2 0x00000 0x10000 0x10000' > /etc/fw_env.config
# EDIT: With Linux 6.1 it became /dev/mtd1!
fw_printenv

If the command still returns an error or nothing, the (custom) environment is still empty and the U-Boot internal defaults are used. To add the defaults to this space, abort boot via serial console, hitting CTRL+C to enter U-Boot console and run:

env save
boot

Now fw_printenv will show the whole U-Boot environment as result, which can be also stored, so it will show it even if it has been erased from SPI:

fw_printenv > /etc/u-boot-initial-env

But this is not needed to change it via fw_setenv, e.g. to generally add support for compressed kernel images:

fw_setenv kernel_comp_addr_r '0x90000000'
fw_setenv kernel_comp_size '0x10000000'
fw_printenv kernel_comp_addr_r kernel_comp_size
cd /boot
gzip vmlinuz-5.15.104
mv vmlinuz-5.15.104.gz vmlinuz-5.15.104
reboot

Starting kernel ...

Not practicable of course, since our packages ship the kernel necessarily uncompressed, just to show the concept.
