On-chip debugger for V850/PHO3, E1?

A year ago I asked questions about on-chip debugging using target V850/PHO3 this in the forum and was recommended to use the E1 device. We have now had some problems regarding adding external RAM, and we suspect that the E1 does not support this. On the E1 product page I now see that V850/PHO3 is listed as not supported. Is this correct? Is there something we can do to get the E1 support the target in question?


Kind regards
