Hi,

Please first update to the latest version of the software:

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
