Steps to re-program the EZ-USB™ SX3 HDMI 4K Capture Card

In EZ-USB™ SX3 HDMI 4K Capture Card Revision 01, there is no provision available to change the boot option using PMODE pins. To re-program the board, the device will need to boot as USB Bootloader Device.

To erase the on-board firmware and to get back the device to bootloader mode, open the command prompt in the folder where HID_Sample_App.exe is located and enter the reset command as shown below:

HID_Sample_App.exe -vid 0x04b4 -pid 0x00c2 -reset

Replace the vid and pid values with corresponding vendor ID and product ID of the connected device. Once it is successful, the “Erase and Fallback to Bootloader is successful” message is displayed as shown in the below screenshot.
