Re: luac to create 32bit Lua byte code

[Tom Sutcliffe <tomsci@...>]

It is very unlikely that the windows version of luac from something like LuaBinaries will produce bytecode that works on an STM32. As I said, Lua bytecode is not some sort of standard format that is compatible across different environments (except by happy coincidence or careful planning). You will have to use the Lua compiler from the STM32 SDK that produced the firmware that is running on your STM32, whatever that is.

This is starting to sound like a "how do I do STM32 development with SDK xyz on a Windows PC" question, which is not something I know anything about, and will also vary wildly depending on exactly what 'xyz' is :-)

Regards,

Tom
