Khodi yochokera padoko la Doom pama foni okankhira batani pa Spreadtrum SC6531 chip yasindikizidwa. Zosintha za Spreadtrum SC6531 chip zimatenga pafupifupi theka la msika wama foni otsika mtengo amtundu waku Russia (zotsalazo ndi za MediaTek MT6261, tchipisi zina ndizosowa).
Kodi vuto la kunyamula linali chiyani:
- Palibe mapulogalamu a chipani chachitatu omwe amapezeka pama foni awa.
- Kuchepa kwa RAM - 4 megabytes (ma brand / ogulitsa nthawi zambiri amalemba izi ngati 32MB - koma izi ndizosocheretsa, popeza ma megabits, osati ma megabytes).
- Zolemba zotsekedwa (mutha kupeza kutayikira koyambirira komanso kolakwika), kotero zambiri zidapezedwa pogwiritsa ntchito uinjiniya wosinthira.
Chip chimachokera pa purosesa ya ARM926EJ-S yokhala ndi mafupipafupi a 208 MHz (SC6531E) kapena 312 MHz (SC6531DA), imatha kutsika mpaka 26 MHz, zomangamanga za ARMv5TEJ (palibe magawano ndi malo oyandama).
Pakalipano, gawo laling'ono la chip ndilomwe laphunziridwa: USB, skrini ndi makiyi. Chifukwa chake, mutha kusewera ndi foni yanu yolumikizidwa ndi kompyuta kudzera pa chingwe cha USB (zothandizira masewerawa zimasamutsidwa kuchokera pakompyuta), ndipo palibe phokoso pamasewera.
Pakadali pano imayenda pa mafoni 6 mwa 9 oyesedwa kutengera chip SC6531. Kuti muyike chip ichi mu boot mode, muyenera kudziwa kuti ndi kiyi yotani yomwe mungagwire pa boot, makiyi amitundu yoyesedwa: F+ F256: *, Digma LINX B241: pakati, F+ Ezzy 4: 1, Joy's S21: 0, Vertex M115: mmwamba Chithunzi cha C323: 0.
Makanema awiri adasindikizidwanso: ndi chiwonetsero masewera pa foni ndi kuyambitsa 4 mafoni ena.
PS: Chinthu chofananacho chinasindikizidwa pa OpenNet, nkhani zochokera kwa ine, zongosinthidwa ndi woyang'anira malo.
Popanda layisensi, ndizovuta kunena kuti chiphatsocho chiyenera kukhala chotani pa code yomwe imapezeka ndi reverse engineering, ganizirani ngati copyleft - kukopera ndi kusintha, ena asinthe.
Masewera a Doom adagwiritsidwa ntchito kukopa chidwi, mwachitsanzo, ndikufuna fimuweya yaulere pama foni am'manja. Tchipisi zawo zimakhala zamphamvu kwambiri kuposa zomwe zimagwiritsidwa ntchito mu firmware. Kuphatikiza apo, zida zake ndizotsika mtengo komanso zofala, mosiyana ndi mafoni osowa omwe ali ndi ma OS "otseguka" kapena omwe amakulolani kuti muzitha kuyendetsa ma code anu. Pakadali pano sindinapezepo wina aliyense woti ndigwirizane naye, ndipo uinjiniya wosinthika ndi wovuta. Malo abwino oyambira angakhale kupeza kasamalidwe ka khadi la SD ndi kasamalidwe ka mphamvu kuti mutha kugwiritsa ntchito mafoni awa ngati cholumikizira masewera. Kuphatikiza pa Doom, mutha kunyamula emulator ya NES/SNES.
