1. Kana chigadzirwa chaburitsa bug inoda kugadziriswa, haigone kugadziriswa online.
2. Haikwanisi kuziva zvinyorwa zvekare uye zvitsva, kudzokorora kwakadzokororwa kwakaitwa apo mafaira e data haana kuchinja.
3. Paunenge uchivandudza mumabheti, chigadziro chimwe nechimwe chinoda kuiswa mukadhi zvakasiyana kana kuvandudzwa nekombiyuta yepamusoro yekombiyuta.
1. Mazano ekugadzira
1) Boot kurodha chirongwa chekusimudzira, pane nguva dzose chidimbu chekodhi yekurodha chirongwa muhurongwa, uye kodhi inoitwa pakutanga.Zvichienderana neNor Flash vhezheni mutsauko wenhamba, inotongwa kuti imhanye iyo iripo vhezheni yechirongwa kana kudhawunirodha chirongwa chitsva kubva kumugadziri.
2) Kana iyo DWIN skrini ichibatidzwa uye kugadzirisa zvakare, iyo pa-chip loader inotanga kuurayiwa, uye yazvino vhezheni nhamba yefaira yega yega data inochengetwa muNor Flash kero sehwaro hwemutongo unotevera kana iyo data data inoda be updated.(Cherechedza kuti yazvino vhezheni nhamba yefaira re data inofanira kuchengetwa mushure mekunge faira re data rakwidziridzwa zvinobudirira).
3) Iyo huru control board inotonga kana Diwen Screen inoda kudhawunirodha chirongwa chitsva zvinoenderana nemusiyano weiyo vhezheni nhamba.Kana iyo vhezheni yenzvimbo nhamba yakasiyana neyekupedzisira yakagadziridzwa vhezheni nhamba, iyo huru yekudzora bhodhi inotumira chikumbiro chekuvandudza chirongwa kuDivin skrini, uye iyo kernel faira inotumirwa kuDWIN skrini nekuchinja SD kadhi chiratidzo mutsara kuburikidza nerelay.
4) DWIN skrini inogamuchira zvitsva zvekushandisa uye inonyora muFlash yekunze mushure mekusimbiswa kwekupedzisira.Kana chirongwa chekuvandudza chaitwa, gadzirisa iyo DGUS system uye ita chirongwa mu-on-chip RAM.Kana ikagadziridzwa zvakare, iyo iri pamusoro pekuita basa rekuita inodzokororwa.Ingani nhamba dzakasiyana dzeshanduro dziri pano, mangani mafaera achagadziridzwa kudzivirira anodzokororwa ezveshanduro imwe chete.
