Disclaimer of caution
This procedure is intended for manufacturing and virgin modules only and should be never applied for shipped iMX6 Rex Modules.
BE AWARE THAT E-FUSES PROGRAMMING IS A NON REVERSAL PROCESS! WARRANTY CLAIM CAUSED BY IMPROPER E-FUSES PROGRAMMING WILL NOT BE ACCEPTED!
Information
This procedure will enforce loading firmware from SPI3 port and will set a unique MAC address.
Description
Production procedure consists of following steps:
- Short BOOT_MODE (JP2) jumper on iMX6 Rex Base Board
- Connect RS-232 port to serial terminal (Settings: 115200 8n1)
- Connect USB_OTG port to host PC utilising microUSB-USB cable
- Power on iMX6 Rex Development Kit
- Execute Manufacturing toolkit at host PC
- Press Start button (iMX6 Rex board will boot firmware loaded over USB)
- Wait until firmware (U-Boot) is booted (serial terminal)
- Burn eFuses over serial terminal
- Remove BOOT_MODE jumper
- Power off iMX6 Rex Development Kit
Requirements
- microUSB-USB cable
- UART cable
- 12V Power supply
- iMX6 Rex Development Kit (with USB0 routed modification: USB OTG connector in use R62, R65 assembled
- Windows PC equipped with MfgTool feature and serial line terminal
Configurations
Production-Rex-basic.bat # Production module i.mx6d 512MB Production-Rex-pro.bat # Production module i.mx6q 2GB Production-Rex-ultra.bat # Production module i.mx6qp 4GB
Procedure
Select appropriate BAT file and start the bootloader transfer over USB OTG interface:
580px
Wait until the process is finished:
430px
The board boots from the loaded firmware:
580px
E-Fuses
This operation is not reversible and should be executed carefully! The iMX6 Rex Module must be replaced in the case of error.

Testing configuration
To check if E-Fuses were setup correctly, test procedure consists of following steps:
- Ensure that BOOT_MODE jumper is not present
- Plug micro SD card with valid testing firmware (or plug SATA disk if SATA booting was selected)
- Power on iMX6 Rex Development Kit
- On-module red LED must start flashing automatically (bootloader was executed and kernel loaded)
- Power off iMX6 Rex Development Kit
