wineusbdm

A DLL for use with Wine to allow use of the USBDM with CodeWarrior.

USBDM is software and hardware for flashing and debugging some microcontrollers. I need to use it for a class I'm taking.

The IDE and toolchain run fine in Wine, except for the debugging and flashing part. It seems like the USB support in Wine isn't really there yet.

The Wine project implements Windows DLLs using code that runs on Linux. I can use the same tools to implement the DLL that the IDE uses to talk to the hardware.

This repository contains some code that forwards calls from the DLL to the native Linux library.

The two symbols USBDM_ControlInterface and USBDM_ICP_SetCallback are currently unimplemented. The first doesn't seem to exist in the Linux library, and the second would need a simple wrapper to translate between calling conventions (but I haven't needed it yet).

Building

This assumes you have the 32-bit version of the USBDM library in the library search path.

winegcc usbdm.spec -shared -m32 -o usbdm.4.dll usbdm.c -lusbdm

Alternatively, a Nix flake and derivation is included in this repository.

Usage

One way is to replace the usbdm.4.dll file in C:\Program Files\Program Files\Freescale\CWS12v5.1\Prog\gdi.

Another way, without modifying any files, is running the program with WINEDLLOVERRIDES set:

WINEDLLPATH=<path> WINEDLLOVERRIDES=usbdm.4=b wine IDE.exe

Cachix

There is a Cachix binary cache for this repository:

cachix use usbdm-flake
cachix use wineusbdm

License

It seems like USBDM itself is GPL, so this is GPL.
