iMX6 TinyRex Base Board contains SPI Flash memory which can be used for bootloader storage and acts as an alternative to default SD card firmware location. This guide shows how to flash u-boot and configure it. There is also a possibility to update efuses in an existing module to use SPI memory by default.
Recommended HW:
- PC with USB port
- Voipac iMX6 TinyRex Development kit in Ultra configuration
- USB to Micro-USB cable
- Ethernet cable
Recommended SW:
- Serial line terminal
- The appropriate file
- TFTP server with the image file stored
Procedure
Note: In case of booting malfunction, follow USB Booting steps to load the firmware from a PC.
Stop autoboot in your serial line terminal. Copy and paste commands separately to download appropriate bootloader file from TFTP server:
setenv ipaddr 192.168.1.150 setenv serverip 192.168.1.75 mw.b 0x10800000 0xFF 0x80000 tftp 0x10800000 u-boot-imx6-tinyrexultra-2.3.imx; sf probe 0:0;sf erase 0x0 0x80000;sf write 0x10800000 0x400 0x7fc00
The bootloader is written to Base Board SPI Flash after automatic download from the TFTP Server:
600px
Reset the board. iMX6 TinyRex Module will start booting from SPI Flash. The bootloader will start to download Image from the TFTP server by default:
600px
To change bootloader environment, stop autoboot:
600px
