Hi,
Could you please provide us with more details about the issue you are facing?
Can you attach screenshot of the download error?
Which demo code are you trying to download? Does it run correctly in the debugger but crashes after POR?
There is a known issue related to RCHW setup if the compiler optimization is set to level 3 (Release Build Configuration). This causes the objects are allocated in reversed order - reset vector is swapped with rchw word and the device does not boot-up after POR. This should be fixed in the next release. I attached fixed file (flashrchw.c).
If this is your case please replace this file in your project and rebuild.
Regards,
Stan
