Hello All,

we have T2081 custom board based on T2080RDB-PC,

in the custom board we have connected F-RAM(CY15B102Q-SXE) via SPI bus,

For connecting the F-RAM peripheral via SPI, what changes we have to do,

or do we have to write a new driver program for the interfacing T2081 and F-RAM.

Any suggestion would be appreciated,kindly help to solve this issue.

Regards,

Anshul

The T2080RDB Linux supports SPI-NOR Flash Micron n25q512a. See attached .dts file

This F-RAM uses similar commands as the n25q512a.

It looks like that driver for the n25q512a can be used for CY15B102Q.


Have a great day,
Pavel Chubakov

Hello Pavel Chubakov,

Thank you for the reply.

i have one more doubt,

where to do pin muxing and input output mapping in case to T2080 RDB board,

as in case of IMX6UL we are specifically having pin muxing related header file present in U-boot and kernel,

i am trying to find the same for t2080RDB which i am not getting.

to configure the IO mapping as per the our custom board.

Any suggestion would be appreciated,kindly help to solve this issue.
