Hi,TI Experts,

I am implementing the following boot sequence in UART boot mode and encountering an error:

1.switch dip switch to "uart boot mode", and make sure char "C" appears on /dev/ttyUSB2. Is ttyUSB2 "MAIN_UART" ?

BOOTMODE [ 8 : 15 ] (SW4) = 0000 0000

BOOTMODE [ 0 : 7 ] (SW3) = 1101 1100

2.downloading the tiboot3 via the below command:

sb --xmodem ./tiboot3.bin > /dev/ttyUSB2 < /dev/ttyUSB2

3. dowonloading Timeout,as show below:

Can you please help to solve the error(above setp3)? could you please correct the setps mentioned above ?

Regards
