    Cred ca acel forum este lasat de soarta raspusuri foarte grele si tarzi, incerc sa obtin pinout la aceasta placa.

    Esti convins ca boot loaderul este in flash??? Nu are un SPI gen 25q16 sau ceva asemanator ,smd 8 pini???
    Am rt809h si pot sa te ajut cu scriere lui daca ai dump-ul necesar , nu are rost sa cumperi un programator.
    Fa o foto la placa de baza ...

    Din pacate nu are spi
    Da este in flash a murit dupa comanda asta:

    MOI2900 # nand erase 0 100000

    NAND erase: device 0 offset 0x0, size 0x100000
    Erasing at 0xe0000 -- 100% complete.
    OK
    MOI2900 # nand write.e 2000000 0 100000

    NAND write: device 0 offset 0x0, size 0x100000
    gesita din pacate

    corect era:

    fatload mmc 0:1 c0008000 MOI2900_uboot.bin
    nand erase 0 c0000
    nand write c0008000 0 60000

    Daca ai un dump de nand corect , sau de pe ce sa copiez unul, ti-l pot face fara probleme.
    Ai sters incepand cu primul bit
