As Dalibor opened up to have thoughts on XScale VMs let me say that I'm having better luck with JamVM (interpreted-only) on my IXP425 board, at least the show-stopping thread-problems could be diagnosed and amended on JamVM. If I had some time to spare I would try to see if Kaffe problems may have a similar solution, but currently I have none.
Some other bits I had trouble were located in the Java class libraries and I've sent upstream to Gnu Classpath, which benefits both VMs. :) On 12/2/05, Dalibor Topic <[EMAIL PROTECTED]> wrote: > 임동기 wrote: > > Hi~ > > I'm going to develop digital tv middleware. > > So, I want a java virtual machine. > > I think two methods to use jvm. > > One is personal basis profile of sun's j2me. > > The other is a kaffe vm which is implemented java TV API. > > > > I want to know PBP porting method or use kaffe vm(include java TV API). > > I'm goint to use IXP255(Xscale) board and embeded linux. > > > > What do I do for java TV API? > > I'm in the great hopes that your helps. > > Here is a bunch of links I sent to someone else asking similiar questions: > > I have been looking around a bit, and I found a few things that might be > of interest for your project: > > futuretv <http://www.media.hut.fi/~as75120/2003/english_material/> > > Futuretv is a project of helsinki university i Finland.
