Just a wild guess here, but check the file paths for .bin and PC_Master for your 56F8346 project. Since you used a copy of 56F8357 project, is it possible that your output is being sent into the directories for the 56F8357 project instead of your new one? A quick way to check this possibility would be to run the 56F8346 project, and then examine the time-stamp on the files in the 56F8357 project.

hello,Tom!
The project for 56F8346 did not generate the bin and PC_Master files.
I open freemaster and configure map files :default symbol "elf" and file"Binary ELF..." .But it does not comminucate and appears such errors as "Cannot detect the board information! The communication will be paused.Error code:0x80000101(Response timeout)".
