Non-volatile memory that is byte erasable. Is the response I have obtained is it right?

Sign up or log in Sign up using Google. As Austin said, “flash” is not byte erasable, although if already erased, it is byte writable for “NOR”. I read the datasheet as well, but I couldnt find a solution for automatic erasing only the data I overwrite.

Is this a new piece of SPI code? Is there any way to erase only some of them or overwrite them? 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? You are sometimes better first of all trying to read the device ID rather than the status register for a new piece of code.

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? Does the MSP read that value or a different one?

I’m using ISE Post as a guest Name. Is there any solution? All forum topics Previous Topic Next Topic. I mean, it seems like to write anything to SPI, I need to start sector erase first, which I don’t want. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type.

Stack Overflow works best with JavaScript enabled. So, without being able to erase, a write is not very useful. Email Required, but never shown. Have you got the SPI module configured correctly for phase and polarity?

As Austin said, “flash” is not byte erasable, although if already erased, it is byte writable for “NOR” flash. Do you see a response from the device on an oscilloscope? Things to check since you have not provided any information:. Abhay 30 2 8.

I can use Impact to write and read the code successfully, it works datasheef. When I remove sector erasing at the start of this example code, software stops writing to SPI.

But this example code does not work without erasing first.

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

Please upgrade to a Xilinx. Things to check since you have not provided any information: There is no single byte erase. Did you forget to assert the chip select line? I store configuration data on the SPI, I cannot erase all the data inside the whole sector. 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’: By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms dahasheet Service.

It’s the definitive way to be sure. We have detected your current browser version is not the latest one. This Wikipedia page explains flash memory fairly well.

Does your SPI code datasneet with any other devices? Actually example code runs great as well. By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies.
