Hi,
I have a simple question like these parts are legacy flashes i guess.
Could you please tell me on which boards these were used?
It's used on Faraday A369 evaluation board.
However the u-boot source codes for A369 is still waiting for approval.
Here is the link to u-boot patchwork:
Ok, Thanks for your information.

W25P80 is an 8Mbit flash right, is this name W25P80 or W25P08?
ofcourse, I have seen the same on datasheet as well.
Thanks,
