Hi,

i'm using beaglebone Rev A3, (AM335x processor) with Arago image.

instead of using SD Card to boot, how to boot the AM335x processor by using UART ?

how i load the MLO binary to processor through UART ?

how i load the u-boot to processor through UART ?

i'm using linux os.

Thanks.

See U-Boot User Guide which discusses how to boot from UART:

Hi Michael T,

I followed through steps in your shared link.

But I got stuck at loading u-boot.img, TeraTerm could not transfer u-boot.img to board.

THere was only difference from the guide that I used "Transfer --> ZMODEM --> Send" in stead of "Transfer --> YMODEM --> Send" (Because my TeraTerm have no YMODEM in displayed menu)

Any help?

Thank you,

JPhan

The log on my post here might help you (but I booted over UART a long time ago on AM335x EVM, not BB):
