15@eussNL151415 so when you read something like ¨kado : Downgrade succesfull with special trick¨ - it means that at /that time/ it needed a certain hw trick, that is now solved in software.
15(17:33:54) 01                                 15rau_151415 thank you again and one more question
15(17:34:26) 01?                        15@eussNL151415 sure
15(17:35:08) 01                                 15rau_151415 the RY/BY# goes to rdy (ánd gp4 for old bitstream)
15(17:35:26) 01                                 15rau_151415 what is old bitstream mean ????
15(17:37:17) 01?                        15@eussNL151415 oh
15(17:37:37) 01?                        15@eussNL151415 old bitstream means a progskeet version 1.0 that has not been updated via JTAG
15(17:38:00) 01?                        15@eussNL151415 so the Actel chip inside, has still the ´old bitstream´ firmware inside
15(17:38:56) 01                                 15rau_151415 are there any new versions till now
15(17:39:08) 01                                 15rau_151415 i have the old white one
15(17:39:22) 01?                        15@eussNL151415 you see, sometimes it is not possible to update everything only within the flasher program. Some improvements/solutions require updating the Actel
15(17:40:10) 01?                        15@eussNL151415 dunno if those are out btw, just know that it is still compatible with the old versions if you use the extra wire to gp4
15(17:41:25) 01?                        15@eussNL151415 so in your specific case : wire from RB/BY ps3 > to progskeet RDY and progskeet GP4 (because you are using old ´bitstream´ board
15(17:41:34) 01                                 15rau_151415 thank you v.much
15(17:41:44) 01                                 15rau_151415 and sorry for the interruption
15(17:41:47) 01?                        15@eussNL151415 if you dont use the gp4 wire it falls back to ´compatibility mode´
15(17:42:42) 01?                        15@eussNL151415 so without the positive effects that the improved method has with that extra wire (I think it was better timing and higher speed)
15(21:23:38) 01!                       15milannnnn151415 hi
15(21:24:46) 01!                       15milannnnn151415 is it possible that my nor dump is bad if it has lots of 00 and FF in the bin file (when opened in hxd)?
15(21:25:15) 01?                        15@eussNL151415 yes and no
15(21:25:36) 01?                        15@eussNL151415 even a good dump will have a fair amount of 00 00 00 and FF FF FF blocks in it
15(21:25:52) 01!                       15milannnnn151415 ok
