iMX6 TinyRex Production

Test download

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
