M25P64 Datasheet PDF
There is no single byte erase.
Is there any solution? Does your SPI code work with any other devices? But this example code does not work without erasing first. Is this a new piece of SPI code? Is the response I have obtained is it right?

This Wikipedia page explains flash memory fairly well. Post as a guest Name. As Austin said, “flash” is not byte erasable, datasheet if already erased, it is byte writable for “NOR” flash. Things to check since you have not provided any information: Have you got the SPI module configured correctly for phase and polarity? I read the datasheet as well, but I couldnt find a solution for automatic erasing only the data I overwrite. datashret
Solved: M25P64 SPI Write Problem – Community Forums
We have detected your current browser version is not the latest one. I’m using ISE Abhay 30 2 8. Did you forget to assert the chip select line? Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type.
Did you remember to send a dummy byte after the RDSR command so that the device would send the status register dtasheet Non-volatile memory that is byte erasable.

I did require that before you write datasheef data, you need to erase the old data once programmed, it can not be made back to a ‘1’: Is there any way to erase only some of them or overwrite datasheeh Sign up using Email and Password. You are sometimes better first of all trying to read the device ID rather than the status register for a new piece of code.
Email Required, but never shown.

I store configuration data on the SPI, I cannot erase all the data inside the whole sector. Does the MSP read that value or a different one? The reason for that is the device ID will never change, whereas the status register might change although that depends on the device. Things to check since you have not provided any information:. So, without being able to erase, a write is not very useful.
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? Please upgrade to a Xilinx. As Austin said, “flash” is not byte erasable, although if already erased, it is byte writable for “NOR”. The response is wrong. Do you see a response from the device on an oscilloscope?
It’s the definitive way to be sure. Sign up using Facebook.
