Hi sir,
I am using a flash memory PN named ST M25P40, it has 512K Bytes size.
a custom cypress cx3 firmware being used currently has around 200K Bytes size, so, the SPI memory should have 300K Bytes free space.
- First question
Is it OK recording some data into this "not used" 300K Bytes space?
- Second question,
How to program data into those un-used space?
Thank you

Hi,
To answer your question:
1. It's ok to write data into those space.
2. You can refer to the "UsbSpiRegMode" example program in FX3 SDK.
By specifying the parameter of function "CyFxSpiTransfer", you can write data to specified address.
Regards,
Eddie
