Hi Dhvanil
I am not aware of such i.MX6UL loader tool supporting uart, however seems one can
customize for such purpose ATK ToolKit for old i.MX, supporting uart download:
Programmers (Flash, etc.) (2)
Source Code for the Flash tool used for downloading, programing, dumping and erasing images in Flash memory to the i.MX EVKs (REV 1.71)
Best regards
igor
