Tool/software: Linux
We were having some issues setting up the linux development environment. The boards were not being set up correctly to boot from TFTP/NFS.
After doing a little bit of digging the uboot environment setup script writes the minicom file to be expecting "abort" instead of "stop". Changing this has been successful in setting up the board. Was not sure where to post this, I am not sure if other people have had these issues or if some other part of my U-Boot is wrong to be producing the wrong prompt.
