When the LOADER device is detected, go to the "Advanced Function" tab and enable "Maskrom" mode.

Note: MaskROM is a special type of read-only memory (ROM) made by Rockchip. It is used as an emergency boot mode for repairing or upgrading Rockchip's system chips.

Return to the "Download Image" tab.

• The boot (system bootloader file) is the rk356x-MiniLoaderAll.bin in the flashing tool.
• The system (system image file) is Armbian_23.08.0_rockchip_panther-x2_bookworm_6.1.35_server_2023.06.21.img.gz. Download and unzip it to a local directory.

Fixing the Panther X2 USB Unrecognized Issue

Execute as root user:

sudo -i

The system will prompt for a password.

Run the following commands:

cd /boot/dtb/rockchip
dtc -I dtb -O dts rk3566-panther-x2.dtb > rk3566-panther-x2.dts
sed -i '/usb@fcc00000/{:a;n;/.*dr_mode = "otg";/!ba;s/dr_mode = "otg"/dr_mode = "host"/}' rk3566-panther-x2.dts
dtc -I dts -O dtb rk3566-panther-x2.dts > rk3566-panther-x2.dtb

This command changes the otg to host within the usb@fcc00000 block, meaning it changes the USB mode from OTG to Host mode. The USB device will act as a host, controlling data read and write operations with external devices.

Once the commands are executed, reboot the device for the changes to take effect:

reboot

After the reboot, the USB issues should be resolved, and the USB ports should function as expected in host mode.
