Disclaimer of caution
This procedure is intended for manufacturing and virgin SBCs only and should be never applied for shipped iMX6 OpenRex Single Board Computers.
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 jumper JP2 on iMX6 OpenRex SBC
- Connect UART port to serial terminal (Settings: 115200 8n1)
- Connect USB_OTG port to host PC utilising microUSB-USB cable
- Power on iMX6 iMX6 OpenRex SBC
- Execute Manufacturing toolkit at host PC
- Press Start button (iMX6 OpenRex SBC will boot firmware loaded over USB)
- Wait until firmware (U-Boot) is booted (serial terminal)
- Burn eFuses over serial terminal
- Remove BOOT_MODE jumper JP2
- Power off iMX6 OpenRex SBC
Requirements
- microUSB-USB cable
- UART cable
- 5V Power supply
- iMX6 OpenRex SBC
- Windows PC equipped with MfgTool feature and serial line terminal
Configurations
Production-OpenRex-basic.bat # Production i.mx6s 512MB Production-OpenRex-max.bat # Production i.mx6q 2GB Production-OpenRex-max4g.bat # Production i.mx6q 4GB Production-OpenRex-ultra.bat # Production i.mx6qp 4GB
Procedure
Select appropriate BAT file and start the bootloader transfer over USB OTG interface:
Wait until the process is finished:
The board boots from the loaded firmware:
E-Fuses
This operation is not reversible and should be executed carefully! i.MX6 processor must be replaced in the case of error.
Boot From SPI3
fuse prog 0 5 0x2A000030 fuse prog 0 6 0x00000010
Boot From SATA
fuse prog 0 5 0x00001020 fuse prog 0 6 0x00000010
MAC Address
For example address 00:0D:15:00:D1:75 is used:
fuse prog 4 3 0x000d fuse prog 4 2 0x1500d175
Testing configuration
To check if E-Fuses were setup correctly, test procedure consists of following steps:
- Ensure that BOOT_MODE jumper JP2 is not present
- Plug micro SD card with valid testing firmware (or plug SATA disk if SATA booting was selected)
- Power on iMX6 OpenRex SBC
- On-board red LED must start flashing automatically (bootloader was executed and kernel loaded)
- Power off iMX6 OpenRex SBC
