An here is my problem: i have two pcs of pic 18f452 then i burn the botloader from file mios8 v1.9h selected the file pic18f452>burner>botloader v1.2b.hex with the pickit2, then verified put the pics on core module and start mios studio 2.4.6. the core continusly send: [7720.384] f0 00 00 7e 40 01 f7 i think this is incomplete upload request from core. ...And can not upload mios studio :no: :no: it is possible missing id? in the wiki says that is done trougt a application change id, but it is done trought midi and i not have mios installed. any know the hacking hex file method? any other bootloader for pic 18f452? Thanks
