Feem ntau, kev hloov pauv ntawm cov khoom khov ntawm kev siv lub tshuab ntxhua khaub ncaws tsis zoo yog muab rau thaum lub cim xeeb tsis ua haujlwm, uas yog qhov tsis tshua muaj neeg paub. Cov txheej txheem firmware nws tus kheej yog yooj yim thiab yuav tsis siv sijhawm ntau, tab sis muaj kev pheej hmoo ntawm kev ua kom puas ntawm lub cim xeeb module.
Nws yog qhov tsim nyog
- - Washer;
- - programmer.
Cov Lus Qhia
Kauj ruam 1
Ua ntej tshaj plaws, nws tsim nyog nug peb tus kheej cov lus nug, puas yog nws tsim nyog yuav tsum tshaj sau lub tshuab nco qhov? Feem ntau, qhov teeb meem tsis nyob hauv kev ua tsis zoo ntawm lub cim xeeb module, rau qhov hais tias muaj lwm qhov laj thawj thiab cov kev daws teeb meem, feem, yuav txawv kiag li.
Kauj ruam 2
Yog tias koj txawm li cas los txiav txim siab ua qhov teeb meem, tsis txhob hnov qab tias qhov kev ua haujlwm no tau ua sib txawv rau txhua lub tshuab ntxhua khaub ncaws. Feem ntau nws txhua tus nyob ntawm lub hom thiab qauv ntawm cov khoom siv tau nruab hauv koj lub tsev. Cov firmware version tseem ua lub luag haujlwm tseem ceeb. Qhov kev xaiv zoo tshaj plaws yog ua qhov haujlwm ntsiag to los ntawm lub qhov (tshwj xeeb txuas), uas tsis yog txhua tus qauv muaj.
Kauj ruam 3
Yog tias tsis muaj cov kev sib txuas, cov kev ua haujlwm yuav nyuaj ntau, vim tias Tsis ntev tas los no, muaj ib qho kev sib txuas ua ke rau hauv lub cim xeeb module rau hauv cov txheej txheem ntawm lub tshuab ntxhua khaub ncaws. Yog li, nyob rau theem no, kev kho vaj tse tsuas yog ua tau hauv lub chaw pabcuam, uas, feem ntau, yuav raug nqi ntau dua. Txhawm rau ua lub cim xeeb flashing los ntawm cov processor, koj yuav tsum muaj cov cuab yeej tshwj xeeb, uas them nqi ntau.
Kauj ruam 4
Tam sim no koj yuav tsum tau qhib phau ntawv qhia, uas feem ntau muaj daim ntawv txuas ntawm daim ntawv txuas ntawm cov chav nyob sab hauv tsev. Yog tias koj tsis pom qhov schematic kos duab, koj tuaj yeem tshawb rau lawv ntawm cov chaw raug raws ntaub ntawv. Txhawm rau ua qhov no, hauv lub qhov rais tshawb nrhiav (raws li txoj cai, lub kaum sab xis saum toj), koj yuav tsum nkag mus rau tus qauv ntawm lub tsheb thiab nias tus yuam sij Sau. Xaiv koj lub tshuab ntxhua khaub ncaws los ntawm cov ntaub ntawv tshawb thiab mus rau Ntu Seem.
Kauj ruam 5
Hauv seem no, koj yuav tsum nrhiav phau ntawv (phau ntawv) thiab rub nws los ntawm nyem qhov kab sib txuas. Cov ntawv rub tawm yuav qhib los ntawm kev nyeem ntawv hauv e-phau ntawv (Adobe Reader lossis Foxit PDF Reader).
Kauj ruam 6
De-energize lub tshuab ntxhua khaub ncaws thiab npaj mus rau cov tub sab tub sab nraud. Siv daim duab kos los ntawm daim ntawv hluav taws xob, nrhiav lub cim xeeb thiab sim ua kom nws siv qhov ntev-hau soldering hlau.
Kauj Ruam 7
Qhov muab tau rho tawm tau txuas rau tus programmer, uas pib nyeem cov ntaub ntawv, thiab tom qab ntawd nqa tawm lub firmware. Txhawm rau nruab cov firmware version tshiab, koj yuav tsum rub cov ntawv coj ua los ntawm tib lub xaib.
Kauj ruam 8
Tom qab ua tiav ntawm kev ua haujlwm ruaj khov, nws tseem ua ib qho kev txiav txim siab mus rau hauv Circuit Court rau nws qhov chaw qub thiab sib sau lub cev ntawm lub tshuab ntxhua khaub ncaws.
