Hi,

In the latest/current version of RKit-STM8, there is a bug in the verification and read-out of the flash, that affects both STM8 and ST7. The problems manifests by this error message:

 !!! Error 304: Communication error: Timeout error reading on USB: WDU_Transfer() failed:
 error 0x20000002 ("Invalid pipe number")

We will issue a new release of the kit during the second week of August, that will not show this problem. Until then, this patch should solve it:
ftp://www.raisonance.com/temp/ST/patch_090731_ST7_STM8_Verif.zip

Copy all the files in \bin\... and it should be OK.

Please let us know by answering this post if the patch does not solve all the problems in your situation.

Please accept our apologies for the inconvenience.

Best Regards,

Vincent
