Info
This procedure will enforce loading firmware from SPI3 port and will set unique MAC address.
Description
Production procedure consist from following steps:
- Short BOOT_MODE (JP2) jumper on i.MX6 Rex board
- Connect UART port to serial terminal (115200 8n1)
- Connect USB_OTG port to host PC utilizing microUSB-USB cable
- Power on i.MX6 Rex board
- Execute Manufacturing toolkit at host PC
- Press Start button (The i.MX6 Rex board will boot firmware loaded over USB)
- Wait until firmware (u-boot) is booted (serial terminal)
- Burn efuses over serial terminal
- Flash bootloader over TFTP
- Remove BOOT_MODE jumper
- Power off i.MX6 Rex board
Requirements
- microUSB-USB cable
- UART cable
- 12V Power supply
- i.MX6 Rex board - Modified version (USB0 routed to USB micro connector R62, R65 assembled)
- Windows PC (Mfg_tool, Serial terminal)

E-FUSES
This operation is not reversible and should be executed carefully. The i.MX6 soc must be replaced in the case of error.

Test
Test procedure consist from following steps:
- Ensure that BOOT_MODE jumper is not present
- Plug uSD card with valid testing firmware.
- Power on i.MX6 Rex board
- On-module red LED must start flashing automatically (bootloader was executed and kernel is loaded)
- Power off i.MX6 Rex board
