Other Parts Discussed in Thread: AM1808

For  AM35x and AM37x, I can download one u-boot.bin to SDRAM and execute it via UART using Flash V1.6 tool .

but for AM1808,  I don't know  how to do.

Any idea for it?  thanks!

    Use AISgen to convert the u-boot.bin to a bootable AIS format. See the image below for the settings.

    The entrypoint for u-boot is usually 0xC1080000 so make sure to include that as shown so the boot loader knows where to jump to after it has copied it to DDR.

    You can then use the UART host tool (included with AISgen) to boot the AIS file over UART.
