Dirk, gaula92: are you guys saying that even the leftmost red LEDs are not lit up? That is strange indeed, as the control CPU doesn't have anything to do with the caches, or the SDRAM, for that matter. Both files (.sof and .pof) work for me just fine, even if I recycle power to the board just before programming. I'll build a new version with the caches disabled (that is, only the new TG68K core and the minimig core changes made by boing4000).
Oh, the dropbox links I posted earlier (and the ones I send to you, Dirk, in a message) point to the newest build, as I've simply overwritten the files on Dropbox.
And just to be sure, can you tell me what kind of SDRAM memory chip is on your boards - is it Zentel or something else? Thanks.
EDIT: here is a build with disabled kickstart cache:https://dl.dropbox.com/u/524989/minimig_de1_test1.sofhttps://dl.dropbox.com/u/524989/minimig_de1_test1.pof
