SW4STM32 and SW4Linux fully supports the STM32MP1 asymmetric multicore Cortex/A7+M4 MPUs

   With System Workbench for Linux, Embedded Linux on the STM32MP1 family of MPUs from ST was never as simple to build and maintain, even for newcomers in the Linux world. And, if you install System Workbench for Linux in System Workbench for STM32 you can seamlessly develop and debug asymmetric applications running partly on Linux, partly on the Cortex-M4.
You can get more information from the ac6-tools website and download (registration required) various documents highlighting:

Cannot program STM32F746 - Please help



We are always happy to help when someone ask a question on a subject we can look at; however the FTD2232D is not a supported debug probe, as we concentrate on the ST-provided STLink-V2 and STLint-V2.1, so, as Kevin already mentioned, you would probably get more answers either on the OpenOCD forum, or on the FTDI forums (the FTD2232 is an FTDI chip isn’t it?)

Moreover, if I can give you an advice, being exhaustive when reporting a bug is a good thing, but you should be reasonable: two posts of several hundred lines each do not help people find th erelevent information. It is a lot better to first present the context of your problem (like you do) then, when asked for, provide more detailed information.

Providing such an overly detailed log is counter productive as people will not read it f they do not fask for it but may just skip your message, afraid by its sheer volume; this is not only true here but is part of the standard netiquette that any forum will expect you to follow.
