Debug Connection
The TQMa65xx debug UART is connected via a Microchip USB-to-Serial converter to X37 (micro-USB) on the MBa65xx. A micro-USB/USB-A cable is part of the STKa65xx accessory set. Depending on the host operating system, a driver may need to be installed.

Yocto Deployment
Device assignment
Device assignment:
mmcdev 0 = eMMC
mmcdev 1 = SD Card
Yocto specific command Update eMMC
1. Run the following command in the Uboot shell to create update script:
setenv install_firmware 'echo MBR... && mmc dev 1 && mmc read $loadaddr 0 1 && mmc dev 0 && mmc write $loadaddr 0 1 && echo U-Boot... && mmc dev 1 && mmc read $loadaddr 2 7FE && mmc dev 0 && mmc write $loadaddr 2 7FE && echo U-Boot environment... && mmc dev 1 && mmc read $loadaddr 801 800 && mmc dev 0 &&mmc write $loadaddr 801 800 && echo reserved... && mmc dev 1 && mmc read $loadaddr 1001 1000 && mmc dev 0 &&mmc write $loadaddr 1001 1000 && echo Firmware Partition... && mmc dev 1 && mmc read $loadaddr 2001 10000 && mmc dev 0 && mmc write $loadaddr 2001 10000 && echo Root FS... && mmc dev 1 && mmc read $loadaddr C001 19F800 && mmc dev 0 && mmc write $loadaddr C001 19F800'
uboot command to start netboot
=> run netboot
