iMX6 TinyRex Production

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

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! 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

Configuration testing

To check that 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
