Hi, Please first update to the latest version of the software from Product Downloads.

Then please note that using multiple RLinks on the same PC is not guaranteed and needs some special care...:

Which software are you using? (you should use STM8_pgm.exe for multiple RLink) If using STM8_pgm.exe, are you using the M option? (required for multiple RLink) Do you experience problems if you are using only one RLink? Best Regards, Vincent
