Here I have installed the TI Sitara SDK 05.05.01. Now I want to begin to do some changes to U-Boot, so I'm in the directory "~/ti-sdk-am335x-evm-05.05.01.00/board-support/board-port-labs/sitara-board-port-uboot". If I do a "make clean", this is the result:
user@ubuntu:~/ti-sdk-am335x-evm-05.05.01.00/board-support/board-port-labs/sitara-board-port-uboot$ make clean
/bin/bash: arm-linux-gcc: command not found
/bin/bash: arm-linux-gcc: command not found
dirname: missing operand
Try `dirname --help' for more information.
user@ubuntu:~/ti-sdk-am335x-evm-05.05.01.00/board-support/board-port-labs/sitara-board-port-uboot$
What may be wrong here?
