Hi all,

I'd like to dump the console output produced by my target (using semihosting) to a file.

If I use fprintf() to log the data directly to a file, the data appears not to be committed until the file is closed. I've tried repeated opening/closing of a log file on the host machine, and it's very slow. Also, it's useful to see the data on the screen as it appears.

So, is there a simple way to copy or redirect console output to a file, other than copy and paste?

Thanks!

Don't know about redirecting console, but you can try using f_sync instead of closing and opening the file. It's there just for that.

I am afraid that there is currently no way of automatically logging the output in the console view out to file, other than copy'n'pasting it.

With regards to the speed of fprintf output, I suggest you take a look at this FAQ:
