Disclaimer of caution

This procedure is intended for manufacturing and virgin modules only and should be never applied for shipped iMX6 TinyRex 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 SD3 port and will set a unique MAC address.

Description

Production procedure consists of following steps:

Short BOOT_MODE jumper on iMX6 TinyRex Base Board
Connect UART port to serial terminal (Settings: 115200 8n1)
Connect USB_OTG port to host PC utilising microUSB-USB cable
Power on iMX6 TinyRex Development Kit
Execute Manufacturing toolkit at host PC
Press Start button (iMX6 TinyRex Module 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 TinyRex Development Kit

Requirements

microUSB-USB cable
UART cable
5V Power supply
iMX6 TinyRex Development kit
Windows PC equipped with MfgTool feature and serial line terminal

Configurations

Production-TinyRex-lite.bat   # Production module i.mx6s  256MB
Production-TinyRex-basic.bat  # Production module i.mx6s  512MB
Production-TinyRex-pro.bat    # Production module i.mx6d  1GB
Production-TinyRex-max.bat    # Production module i.mx6q  2GB
Production-TinyRex-ultra.bat  # Production module i.mx6qp 4GB 
Prototype-TinyRex.bat         # Prototype  module i.mx6q  2GB / i.mx6s  1GB

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 TinyRex Module must be replaced in the case of error.

Boot From SD3

fuse prog 0 5 0x00003040
fuse prog 0 6 0x00000010

Boot From SPI1

fuse prog 0 5 0x08000030
fuse prog 0 6 0x00000010

Boot From SD3 + SPI1 recovery

fuse prog 0 5 0x48003040
fuse prog 0 6 0x00000010

Boot From SATA

fuse prog 0 5 0x00001020
fuse prog 0 6 0x00000010

Boot From SATA + SPI1 recovery

fuse prog 0 5 0x48001020
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 is not present
Plug micro SD card with valid testing firmware (or plug SATA disk if SATA booting was selected)
Power on iMX6 TinyRex Development Kit
On-module red LED must start flashing automatically (bootloader was executed and kernel loaded)
Power off iMX6 TinyRex Development Kit
