CubeMX, IAR code regeneration ''project generation have a problem'' it says

A recurring big problem with CubeMX (all versions. using v4.7/latest now)....

After making pin mapping and peripheral config changes, I run GENERATE CODE, as often I do. Too often I get this from CubeMX:

''The Code is successfully generated under (mypathname), but EWARM 6.70 project generation have (sic) a problem.''

The EWARM 6.70 part is irrelevant - I use a much later version of EWARM.

It's telling me that all the sources were regenerated but it got some unsaid error when regenerating the IAR EWARM project files.

I don't know what I do that causes these errors to begin after many prior error-free sessions. No big changes in file/folder tree arrangement.

If I continue to ignore the error, I can get IAR to build and run with ST-Link OK. I dearly wish the error message would give some semblance of a clue as to the error that occurred.

Hello Steve,

It happens that sometimes some files get set in ''access denied'' mode by EWARM preventing successful MX project generation. Trying to generate again usually works. Please let us know if you have identified some actions that leads systematically to the problem.

Thank you for the reply.

Your recommendation

''Trying to generate again usually works. ''

Do you mean to simply run CubeMX's Generate Code? I've done this many times, before posting here. No help. I can launch the eww file and build/run/debug as usual.

I can't say what causes it - other than generally it happens often, after using CubeMX without error. Once it happens, there's no cure other than to abandon and start anew. This is far too onerous, as I've found no way to more or less export the configs.

I have same problem, too. Try to place your project into folder without spaces and international letters in name. It usually helps to me.

More than one user reports this problem. Spaces in path name isn't the cause.

ST, PLEASE RESPOND.

I have the same problem:

STMCubeMX generates all the code necessary, except it doesn't create a ''EWARM'' directory (nor any content). If I create this myself and use IAR to set up a Project I can use the code generated. What gives?

Edit: If I change the directory to a not so deep path it works! A nested path six directories deep doesn't, but two does.

As for me, a looked toward filepath with spec characters/spaces. for the time CubeMX was installed, it worked good, but today refused to make a EWARM files for me. the reason was a russian-named folders, containing repository.

moving reps to simple-named folder had overcome the issue
