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

Is the response I have obtained is it right? Non-volatile memory that is byte erasable. Things to check since you have not provided any information:. Stack Overflow works best with JavaScript enabled. Things to check since you have not provided any information: Actually example code runs great as well. Do you see a response from the device on an oscilloscope? I can use Impact to write and read the code successfully, it works great.

Does your SPI code work with any other devices? Abhay 30 2 8.

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’: Did you remember to send a dummy byte after the RDSR command so that the device would send the status register value? I store configuration data on the SPI, I cannot erase all the data inside the whole sector. Sign up using Facebook. 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?

Did you forget to assert the chip select line? Sign up or log in Sign up using Google. This Wikipedia page explains flash memory fairly well. Have you got the SPI module configured correctly for phase and polarity? Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. It’s the definitive way to be sure. But this example code does not work without erasing first.

We have detected your current browser version is not the latest one. I’m using ISE When I remove sector erasing at the start of this example code, software stops writing to SPI. Post as a guest Name. ChromeFirefoxInternet Explorer 11Safari.

Please upgrade to a Xilinx. As Austin said, “flash” is not byte erasable, although if already erased, it is byte writable for “NOR” flash. Is there any solution?

You are sometimes better first of all trying to read the device ID rather than the status register for a fatasheet piece of code.

Does the MSP read that value or a different one? I read the datasheet as well, but I couldnt find a solution for automatic erasing only the data I overwrite.

Is there any way to erase only some of them or overwrite them?
