Hi
I tested boot from uart in two sdk environments.
1. sdk version : ti-sdk-am335x-evm-08.00.00.00
make -C /home/user/ti-sdk-am335x-evm-08.00.00.00/board-support/u-boot-2014.07-g7e537bf ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- am335x_evm_spiboot_config all
2. sdk version : ti-processor-sdk-linux-am335x-evm-04.03.00.05
make -C /home/user/ti-processor-sdk-linux-am335x-evm-04.03.00.05/board-support/u-boot-2017.01+gitAUTOINC+c68ed086bd-gc68ed086bd ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- am335x_evm_config all
In the first sdk, uart booing was done normally.
But on the second sdk, I could not run Send Ymodem. Below is a related log.
Starting xmodem transfer. Press Ctrl+C to cancel.

After the Send Xmodem is completed, 'C' is displayed and then 'Send Ymodem' is proceeded but 'C' is not displayed.
I'd like you to check it out.
