Does the MSP read that value or a different one? As Austin said, “flash” is not byte erasable, m255p64 if already erased, it is byte writable for “NOR”. Non-volatile memory that is byte erasable. This Wikipedia page explains flash memory fairly well. It’s the definitive way to be sure. So my question is “Is the response I have obtained is it right? When I remove sector erasing at the start of this example code, software stops writing to SPI.

Is this a new piece of SPI code?

Is the response I have obtained is it right? I can use Impact to write and read the code successfully, it works great.

But this example code does not work without erasing first. By clicking “Post Your Answer”, you acknowledge dztasheet you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies.

I read the datasheet as well, but I couldnt find a solution for automatic erasing only the data I overwrite. The reason for that is the device ID will never change, whereas the status register might change although that depends on the device.

Did you remember to send a dummy byte after the RDSR command so that the device would send the status register value? There is no single byte erase. Sign up using Facebook.


Please upgrade to a Xilinx. Have you got the SPI module configured correctly for phase and polarity? Actually example code runs great as well. Abhay 30 2 8. Stack Overflow works best with JavaScript enabled. We have detected your current browser version is not the latest one. I store configuration data on the SPI, I cannot erase all the data inside the whole sector. Dwtasheet there any solution?


The response is wrong. Sign up using Email and Password.

As Austin said, “flash” is not byte erasable, although if already erased, it is byte writable for “NOR” flash. Is there any way to erase only some of them or overwrite them?

Post as a guest Name. I mean, it seems like to write anything to SPI, I need to start sector erase first, which I don’t want. You are sometimes better first of all trying to read the device ID rather than the status register for a new piece of code. Things to check since you have not provided any information:. So if you don’t need to overwrite data, you should be able to do byte writes.
