Info for W25Q16BVSSIG

[Berké Durak]

Hi,

This is the flashrom -VV output for the W25Q16BVSSIG chip as found
on the Olimex iCE40HX8K-EVB evaluation board.

From the Debian flashrom 1.0-1 armhf on the SPI pins of a Beaglebone
Black, with the command :

flashrom -p linux_spi:dev=/dev/spidev0.0,spispeed=10000 -VV >flashrom.info

Hi Berké,

your "problem" is that you get a GigDevice and not the expected Winbond detection, right?

The ID found is: id1 0xc8, id2 0x4015
The windbond should have (as mentioned in the datasheet):  id1 0x14, id2 0x4015
So they differ in the id1 value.

As 0xc8 and 0x14 differ in many bits I assume that everything is fine and the correct ID is 0xc8.

That´s why I´d like to ask: Where did you get the information that make you expect a Winbond chip from? Did you get it from a Olimex-Datasheet or did you read the chip name from the chip case itself?

Btw: There is a newer version of flashrom. It´s never a bad idea to use the new one to reduce problems. ( https://www.flashrom.org/Flashrom/1.2 )

Regards,

Simon

Hi Simon,

Yes, I got the chip ID from the Olimex schematic, but you're right the
actual chip on the board is a Gigadevice, the marking is 25Q16CSIG.

I'll compile and give the new flashrom a try when I get back to it and
let you know.

Regards

PS. Thanks for flashrom, and sorry for the late reply.
