If so have you checked with an oscilloscope to see what you send out clock and MOSI is what you expect and matches what the datasheet says the device expects? Abhay 30 2 8.

I can use Impact to write and read the code successfully, it works great. So if you don’t need to overwrite data, you should be able to do byte writes. When I remove sector erasing at the start of this example code, software stops writing to SPI.
Things to check since you have not provided any information: Did you forget to assert the chip select line? Sign up using Facebook. The reason for that is the device ID will never change, whereas the status register might change although that depends on the device.
Is the response I have obtained is it right? Do you see a response from the device on an oscilloscope? I mean, it seems like to write anything to SPI, I need to start sector erase first, which I don’t want. There is no single m25p644 erase. Sign up using Email and Password.

Did you remember to send a dummy byte after the RDSR command so that the device would send the status register value?

So my question is “Is the response I have obtained is it right?
