Hi
I am using a AM37x/DM3730 EVM boards for my work. And I am using TFTP for booting up the board. But it does not show login prompt after all the initialization messages are shown. I am using DVSDK DM3730 4.02.00.06 with the board and minicom terminal for RS-232 communication. I have also tried with TeraTerm on Windows and the problem still persists. I have checked the Hardware Flow Control otpion in Minicom and it is disabled as it has to be.
I am pasting my boot log here:
