Tool/software:
I would like to use UART boot as backup boot.
When booting from UART backup boot, I transmitted tiboot3.bin with XMODEM.
The transmission was succeeded but could not be polling to receive tispl.bin.
It seems that starting DDR controller: driverdt->start(pd) could not return.

What is necessary how to use UART boot as backup boot?
The primary boot mode is SD.
For using backup boot, tiboot3.bin in SD is binary that intentionally fail to boot.
tiboot3.bin transmitted with XMODEM is correct binary to boot.
