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

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.
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.

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.
