The mkimage tool adds a checksum and header to this file which can be loaded by U-Boot. The.ub file should not be edited directly.

For users in Windows or OSX we recommend virtualizing a Linux PC.

Most of our platforms run Debian and if there is no personal distribution preference this is what we recommend for ease of use.

Development will include accessing drives formatted for Linux and often Linux based tools.

Disconnect the power source before moving, cabling, or performing any set up procedures.

Different baseboards use different power connectors, voltage ranges, and may have different power requirements.

The TS-4900 draws from 0.85W to 6W depending on how idle the processor is, and if you are using a solo, dual, or quad core.

A typical power supply for just the macrocontroller will allow around 1.5A5V, but a larger power supply may be needed depending on your peripherals.

The next section of the manual provides information on getting the console connected.

If the SD boot jumper is set, it will boot to the Linux on the SD card.

If you env save this will use your environment on the disk, but on new boards the SPI flash is erased so it just doesnt have a modifed env saved.

The TS-8550 baseboard brings out a DB9 connector with the console as RS232.

Other baseboards have a jumper to switch between the console port and another serial port.

Refer to the baseboard model you are using MainPageBaseboardshere for more information on any specific jumpers or ports to connect to for console.

These examples demonstrate all three applications and assume that the serial device is devttyUSB0 which is common for USB adapters.

Be sure to replace the serial device string with that of the device on your workstation.

This allows you to include your boot image on either the SD, eMMC, SATA, NFS, or USB.

U-boot is a general purpose bootloader that is capable of booting into common Linux distributions, Android, QNX, or others.

On our off the shelf baseboards this pin is brought out as the SD Boot jumper.

Our default build has 2 MiB of environment space which can be used for variables and boot scripts.
