mox-imager - a tool for manipulating / uploading Marvell's Armada 3720 firmware

Features over Marvell's original WtpDownloader:

• can upload firmware over UART faster (with baudrates up to 6 MBaud)
• can upload flash-image.bin over UART (the code changes the SPI bootflashsign to UART)
• can upload firmware over UART in separate images without headers (filename arguments must be supplied in correct order)
• mini-terminal (implementation from U-Boot's kwboot)

Other features:

• create ECDSA signed images (Turris MOX boards are locked to only boot signed firmware)
• burning board information to OTP (MAC address, serial number, signing key) - currently implemented for Turris MOX
• read eFuse OTP memory

Usage

Upload firmware over UART

Can upload unsigned images as WtpDownloader

mox-imager -D /dev/ttyUSB0 .../uart-images/{TIM_ATF.bin,wtmi_h.bin,boot-image_h.bin}

Can upload signed images as WtpDownloader

mox-imager -D /dev/ttyUSB0 -E .../uart-images/{TIM_ATF_TRUSTED.bin,TIMN_ATF_TRUSTED.bin,wtmi_h.bin,boot-image_h.bin}

But can also upload unsigned flash-image.bin over UART

mox-imager -D /dev/ttyUSB0 .../flash-image.bin

And can also upload signed firmware in separate images

mox-imager -D /dev/ttyUSB0 .../trusted-secure-firmware-uart.bin .../a53-firmware.bin

Send escape sequence before uploading (to force boot from UART)

mox-imager -D /dev/ttyUSB0 -E .../flash-image.bin

Upload with higher baudrate (-b BAUDRATE flag)

mox-imager -D /dev/ttyUSB0 -b 3000000 .../flash-image.bin

Upload and start mini-terminal after uploading (-t flag)

mox-imager -D /dev/ttyUSB0 -t .../flash-image.bin

Upload with maximal baudrate 6000000 and start mini-terminal

mox-imager -D /dev/ttyUSB0 -b 6000000 -t .../flash-image.bin

Only start mini-terminal (like minicom/kermit) without uploading

mox-imager -D /dev/ttyUSB0 -t

Read device eFuse OTP memory

mox-imager -D /dev/ttyUSB0 -E -Rauto

Print image info

mox-imager .../flash-image.bin

Also disassemble GPP packages

mox-imager -S .../flash-image.bin
