Merhaba Arkadaşlar.
Öncelikle, RcALTIN Hocama çok ama çok teşekkür ediyorum, onun sayesinde baya yok katettim, hocama başarılar diliyorum ve bootloader la olan çalışmalarını dört gözle bekliyorum . Arkadaşlar ds30Loader ile 485 üzerinden yükleme yapıyorum fakat yükleme yaparken birkaç sorun yaşadım ve bir türlü çözemedim.

"don't write goto at 0x00" işaretli iken programı ds30loader ile attığımda, bootloader çalışıyor fakat benim program çalışmıyor.
"don't write goto at 0x00" işaretli değil iken programı ds30loader ile attığımda, bootloader iptal oluyor birdaha bootloaderı ds30loader ile göremiyorum  fakat benim program çalışıyor.

Bu bootloader dosyasını  pic e yükledim. Daha sonra Benim kodu ccs de derledim ve ds3loader ile 18f452 ye yükledim. Yükleme ile ilgili birkaç sorun var sanırım. ccs kodunun içerisine kodmu eklemem gerekiyor bilemiyorum
Yardımcı olabilirmisiniz acaba.
