Hello:
Thanks for the valuable response.
In my case I had created only BOOT partition on my SD Card and I copied the
MLO, U-boot.img and uEnv.txt files.
the content in the uEnv.txt is as follows:
*uenvcmd=setenv bootargs console=ttyUSB0,115200n8 console=${console}*
*echo *** Booting To Baremetal_1 ****
Before applying USB power to BBB, SD card is inserted and I pressed and
hold the Switch-2 to boot from SD Card.
But there is no response from the board at USB0 port.
Is it problem with uEnv.txt file.?
Are there required for any changes.?
Thanks And Regards,
Siva Prakash Reddy
