I am trying to follow the instructions at “http://processors.wiki.ti.com/index.php/Sitara_Linux_Training:_Uboot_Board_Port”. I am not able to down load the u-boot file. I am using a BeagleBone Black and a USB to serial cable connected to J1 on the BBB. I am running Linux Mint 17.2 on the development PC. I have downloaded and run “ti-sdk-am3517-evm-06.00.00.00-Linux-x86-Install.bin”. I have cloned the sitara-board-port-linux git tree in the “/home/sitara/ti-sdk-am335x-evm-06.00.00.00/board-support/board-port-labs” directory by executed “git clone https://gitorious.org/sitara-board-port/sitara-board-port-uboot.git”. I am running minicom 2.7 with Serial Device set to /dev/ttyUSB0. I have checked-out the tag in the git tree by executing “git checkout 06.00.00.00-template” from the “/home/sitara/ti-sdk-am335x-evm-06.00.00.00/board-support/board-port-labs/sitara-board-port-uboot” directory. I have compiled u-boot by executing “make ARCH=arm CROSS_COMPILE=/home/sitara/ti-sdk-am335x-evm-06.00.00.00/linux-devkit/sysroots/i686-arago-linux/usr/bin/arm-linux-gnueabihf- am335x_evm”. I have downloaded the SPL (“u-boot-spl.bin” file) from the “/home/sitara/ti-sdk-am335x-evm-06.00.00.00/board-support/board-port-labs/sitara-board-port-uboot/spl” directory, by selecting it in minicom then applying power to the BBB while holding the Boot button (S2).
