The result looks as if you are reading random data... either your
connections are wrong/bad, or the board is disturbing the communication
on the SPI bus. See also http://flashrom.org/ISP

Flashrom reading/writing Pm25LV512 issue

[Tudoran Mihail]

Hi Stefan,

I removed the chip from the board, now it is connected directly to the
CD4050, i triple checked all the wiring.
I think it should be something wrong with the arduino, I know the 25LV512
is functional because the LCD boots fine with it.

I also tried connected it directly to the Arduino, without the CD4050
converter, still the same. I did not damage the chip, the LCD still boots
with it.

Thanks !!!
