Korunmali flaslari desifre etme

---

Bildindigi uzere sadece iki turlu flash kiliti vardir:
Birincisi hardware kilit
Ikincisi software/hardware combinasyonu kilit
Asagida resmi gosterilen flaslarin ayni sifre configurasyonu ve hardware desifresi
vardir

Type1 " Harsdware Unlock" :

Intel : TE28F400B3, 28F800B3, 28F160B3, 28F320B3
Sharp : LH28F800XXX, LH28F160XXX
Atmel : AT49BV16x4A(T), AT49BV162A(T)






Notlar:
1-WP numarasi sifre atmel flaslarinda bulunmamaktadir ve Vpp, WP numarasi oteki sozu edilen oteki flaslarda bulunmaktadir.
2- Vpp,WP# sifreleri control sifreleridir.
3-Bilgisayarinizin paralel portunun (kapisinin) EPP/ECP ye kuruldugundan emin olmaniz
gerekir. Eger degilse BIOS degerlerini EPP/ECP ye donusturun. Ayrica Paralel port
adresini not alin. Normal olarak 378 dir.

Islemler:
1-Flash Atmel ise VPP sifresinin dogrudan dogruya processor'a yada PNP transistorunun
collector'una bagli oldugundan emin olun.
Eger flash Atmel'den baska ise WP numarasinin ve Vpp nin dogrudan dogruya processor'a yada PNP transistorunun collector'una bagli oldugundan emin olun.
2-Eger dogrudan dogruya processor'a bagli ise, onlARI VE vpp yi birbirine bagliyan
kabloyu kesin (Atmel flaslari icin), oteki flaslar icin VPP ve WP# 3.3v ye baglayin.
Eger dogrudan dogruya PNP trasistor'unun collector'una bagli iseler onlari direct
olarak herhangi 3.3v ye baglayin. Bu durumda kesmenize gerek yok.
NOte: Cogu alicilarin WP numarasi ve VPP sifresi birbirine baglidir veya WP numarasi
3.3v vcc sifre 47 flasda ve Vpp Pnp transistorunun collector'una bagilidir.

3-JTAG paralel fisini bilgisarinizin paralel portuna baglayin ve aliciniza power verin.
(Electrige baglayin demek istiyorlar zannedersem.)
4-Wall 'i baslatin. Adimlar:
a)Ok tiklayin uyari (Warning) mesaginda.
b)Reset Up 3 kere tiklayin. Her tiklamadan sonra uyari mesaginda ok ye tiklayin.
c)Wall'i bilgiyarinizin ekraninda acik birakin.
5-J***s baslatin. Processorunuzin tipini asagidaki sekilde tanimasi gerekir :

Device ID : 0x1D405041
Device : STi5518BVC

6-IDR modelini secin
7-Flash programining'a tiklayin. Hemen programlamaya baslamasi gerekir.
8-J***s flash tipini hemen tanimasi gerekir. Programing Panelini aciniz. Eger Mfg veya
Device ID hakkinda Error (Yanlis) mesagi alirsaniz hersey yolunda gitmemis demektir.
J***s.def documaninin dogru oldugunu teyit edin.
9-Flashi silip yeniden programlayabilirsiniz.
10-Programlamayi tamamladiginizda IRD yi fisden cikarip oteki baglantilarini kapatin.



Ikinci tip Harware/Software acilimi

Intel : TE28F400C3, 28F800C3, 28F160C3, 28F320C3
ST : M28W800CB , M28W800CT, M28W160CB , M28W160CT

Islemler:
Yukaridaki ilk 6 adimi ayni sekilde uygulayin.
7-Bu adim Processor'a (Omega) emir gonderip bize yolu acar. Development Panel'ina
tiklayin. Orada soylenen adimlara onem vermeyin. Sadece Ok'ye tiklayin.
8-Development Panelinin Sol tarafinda asagidakini yazin:

Address: 2000E020 (all ‘0’s are zeros)
Data: 01
Write Byte'e tiklayin.

9-Bu adim flash ciplerindeki ozel kiliti acar. Ornegin eger 7FE00000 adresinde Sector 0
SA0 acmak istiyorsanin asagidaki adimlari takip edin:
Development Paneli acikken asagidakini yazin:

Address: 7FE00000 (hep ‘0’s are sifir)
Data: 60 (alti/sifir) Click Write Byte
Data: D0 (‘D’-sifir) Write Byte'a tikla
Data: FF Write Byte'a tikla

Boylece SA0 actiniz.
Eger oteki sektorleri acmak isterseniz onlar icinde baslangic adresleri ile yukarida
soylenilenleri yapin
10-Development Panel'ini kapatin.
11-Flash Programing'a tiklayin ve oteki gerekli adimlari uygulayin.
