Trebuie scris EMMC-ul.Am facut eu vreo 4 placi...Am documentatia si binurile.Sunt 4.(BOOT 2 NU SE SCRIE ESTE 0)

User.bin,

boot1.bin,

boot2.bin,

extcsd.bin,

rpmb.bin

Se scrie pe ISP (5 FIRE),,,e simplu ori cu RT ori cu TNM.

Pentru aceasta placa sunt 2 versiuni 3D SI FARA 3D.

Si se scrie toate intr-un emmc?

EMMC are 4 GIGA .,,e destul de mare..dar merge scris la fel de repede ca un NAND.

Fiecare placa are particularitatile ei...la unele boot e de 1024,,,,la altele 4096...

La fel difera 3D SAU FARA 3D....

Binurile se pot copia usor din placi functionale....

Buna ziua tuturor. Am si eu un TV Samsung UE42F5500aw si am acelasi defect cred...

Porneste apare Smart TV  apare imaginea cu postul tv respectiv si dupa cateva secunde se restarteaza, daca intrii in menu tv poti umbla ctava secunde 5-10 dupa care se blocheaza si se retarteaza.

 

Nu pot face reset din menu de service pentru ca  nu am timp , se restarteaza prea repede

Imi poate da si mie cineva un bin de scris pentru cele doua memorii ??

Multumesc.
