You are sometimes better first of all trying to read the device ID rather than the status register for a new piece of code. Do you see a response from the device on an oscilloscope? Have you got the SPI module configured correctly for phase and polarity? Did you forget to assert the chip select line? Sign up using Facebook.

If so have you checked with an oscilloscope to see what you send out clock and MOSI dqtasheet what you expect and matches what the datasheet says the device datasheett

Stack Overflow works best with JavaScript enabled. Does the MSP read that value or a different one? Post as a guest Name. Is there any solution?

So if you don’t need to overwrite datashedt, you should be able to do byte writes.

M25P64-VMF6P

The reason for that is the device ID will never change, whereas the status register might change although that depends on the device. As Austin said, datasneet is not byte erasable, although if already erased, it is byte writable for “NOR” flash. As Austin said, “flash” is not byte erasable, although if already erased, it is byte writable for “NOR”. But this example code does not work without erasing first.

Email Required, but never shown. Is the response I have obtained is it right? I read the datasheet as well, but I couldnt find a solution for automatic erasing only the data I overwrite. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. I can use Impact to write and read the code successfully, it works great. Things to check since you have not provided any information: I did require that before you write new data, you need to erase the old data once programmed, it can not be made back to a ‘1’: Please upgrade to a Xilinx.

So my question is “Is the response I have obtained is it right? ChromeFirefoxInternet Explorer 11Safari. There is no single byte erase.

Non-volatile memory that is byte erasable. The response is wrong.

Actually example code runs great as well. This Wikipedia page explains flash memory fairly well. It’s the definitive way to be sure. When I remove sector erasing at the start of this example code, software stops writing to SPI.

I mean, it seems like to write anything to SPI, I need to start sector erase first, which I don’t want. Is there any way to erase only some of them or overwrite them?

All forum topics Previous Topic Next Topic. Things to check since you have not provided any information:. Did you remember to send a dummy byte after the RDSR command so that the device would send the status register value? So, without being able to erase, a write is not very useful. Sign up or log in Sign up using Google. I store configuration data on the SPI, I cannot m2564 all the data inside the datasehet sector.

I’m using ISE Does your SPI code work with any other devices? We have detected your current browser version is not the m255p64 one.
