What are the differences/similarities between supernova and helium flash?

I tried to search the internet but could not find a direct comparison. Is there any link between supernova and helium flash? If so, what is it? otherwise how they are different?

The helium flash is caused by the explosive ignition of helium in the electron-degenerate core of a low mass ($$<2M_{\odot}$$) star, that terminates the ascent up the red giant branch.
A supernova can be one of two basic types. A type II is the core collapse of a massive star ($$>8M_{\odot}$$). About the only point of similarity here is that the core of the star is supported by electron degeneracy pressure prior to the collapse. Not much else is similar, since there is no explosive fusion process inititated.
