Hi ,

I just bought 2 STX Rlink for replacement of the old STICK programmer.

With my old STICK programmer, I have to set the Option Byte  to get E7, 45

But when Itried to erase the IC it gave me error like: Unable to install the ICP driver in Ram on SFlash7.

On the STVP it gave me error like cannot communicate with device etc...

In some case it can erase but gave me error that the erase has failed and cannot reprogramme the board any more.

Could you help ASAP.

Thank you.

  1. please check your are selecting the right MCU
  2. The adaptator switchers
  3. The Rlink driver
