Witam,
Walczę już kilka długich dni z płytą NM+-C741 rev 1.0 z laptopa Lenovo.
Mój problem to brak komunikacji z Nuvoton NPCE68APA0DX. Zakupiłem specjalnie do tego celu SVOD-a 4 i żadna z informacji dostępna w sieci nie pozwoliła mi skomunikować się programatorem z układem. Z baterią czy bez bez skutku. Nie wiem już co robię źle (czasem jak się człowiek zafixuje to tak wychodzi) .
Za skuteczną pomoc w rozwiązaniu tego problemu oferuję nagrodę w wysokości 200pln przelewem na podane konto.
Z góry dziękuję za pomoc.

1/ is your MB working?...so we know that KBC should communicate
2/ for SVOD4 to communicate with NPCE68APA0DX are RDY, JENK, TCK, TMS, TDI, TDO signals needed - as in SVOD online databese is NM-C741 not uploaded yet, what is your config?...
3/ do you set after selecting Mode of programmer - config NUVOTON 256K, NPCE38/48/58/68

Hello!

To read this KBC chip, the machine must be initialized.
To do this, connect the Svod programmer to the board, connect the hard drive, and also connect the main battery. Then boot the machine into the OS and shut it down. Only then try to read the KBC chip.
