Is it possible to fix unknown JEDEC ID?

Thanking you in anticipation.

Works! 💯 👍 Great, thanks.

Tested press and hold reset button and web server firmware/u-boot updates as well:

Keep button pressed for at least:
- 3s for web based recovery
- 5s for U-Boot console
- 7s for network console

. . . 0x3 seconds

HTTP server is starting for firmware update...

eth0 link down
enet1 port2 up
HTTP server is starting at IP: 192.168.1.1
HTTP server is ready!

It Works. 😃

You can add 4 MB GigaDevice GD25Q32 here to currently supported FLASH types.

Thanks.
