Hello guys and gurus,
 

I'm new with the SX28 (not new to microcontrollers, though) and entering matters with the SX-Key Tech Tool Kit.

I have installed Sx-Key v3.2.92h BETA, because this would support the USB-Key I got with the kit.

I'm writing Assembler, at this time writing the typical "blinking LED" samples and studying port configuration and stuff.

 

What happens from time to time is, that I have a program loaded and running, have made some changes to the source and want to reprogram for debugging, when all of a sudden a message box says Chip connect failed, and when retrying, it says SX-Key not found on COM4. I disconnect the SX-Key, switch of the board and retry, sometimes successful, sometimes I have to retry several times before it works.

 

Also for some reason the clock frequency seems to be wrong when entering debug modus. Just a couple of minutes ago it happended to change at random. After entering debug the blinking was rather slow and after 2 or 3 seconds it went to the expected speed, without me doing anything at all.

 

I have to say, most things worked as expected, but I feel a little unsure about the described behaviour.

Anybody else experienced such problems? Maybe it's an already known BETA software issue?
