Willem 4.5C and SPI flash

Сообщение banana29 » Ср июл 07, 2010 9:02 pm

hi,

I am Dario from Italy.

I need to program a MX25L4005A (EEEPC900 bios corrupted) with my Willem PCB4.5C from Sivava... i've read about a little mod to apply, to extend compatibility to SPI flash (like Willem PCB5.0); i need some schematics ad infos about that mod, please

thanks in advance


Dario

Need mod to apply existing voltage reduction (jumper, 2diods) for SPI socket.
In my sample - 2 line cuts and 2 wires. Find here

thank you very much!

I've done this mod without problem, now i can read/write SPI flashes with my Willem4.5C (tested some minutes ago).

i have only a question: with this mod, may i have problems with other kind of devices?

No. You have to set jumper Open 3.6V for 5V serial EEPROM.
