I have noticed that the linux branch of the git repository of MfgTool (https://github.com/NXPmicro/mfgtools.git) is presumably no longer maintained (last change was in September 2018, while some commands cause segmentation faults and other forum threads suggest is does not work). We plan to move from a i.MX RT1064 to a i.MX RT1060, and so we must be able to generate bootable external flashes using a linux machine. How do you suggest we proceed? "elftosb" seems to work, at least at first glace.
Thanks in advance.
