I store configuration data on the SPI, I cannot erase all the data inside the whole sector. You are sometimes better first of all trying to read the device ID rather than the status register for a new piece of code.

I can use Impact to write and read the code successfully, it works great. Non-volatile memory that is byte erasable. 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?

Did you forget to assert the chip select line? Does the MSP read that value or a different one? Actually example code runs great as well.

Is this a new piece of SPI code? All forum topics Previous Topic Next Topic. There is no single byte erase. I’m using ISE Things to check since you have not provided any information:.

Email Required, but never shown. This Wikipedia page explains flash memory fairly well. Is there any way to erase only some of them or overwrite them? Is there any solution? Abhay 30 2 8.

Stack Overflow works best with JavaScript enabled. 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?

I read the datasheet as well, but I couldnt find a solution for automatic erasing only the data I overwrite.

Have you got the SPI module configured correctly for phase and polarity? So, without being able to erase, a write is not very useful.

MSP SPI to M25P64 – Stack Overflow

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’: So my question is “Is the response I have obtained is it right? If so have you checked with an oscilloscope to see what vatasheet send out clock and MOSI is what you expect and matches what the datasheet says the device expects?

Is the response I have obtained is it right? The reason for that is the device ID will never change, whereas the status register might change although that depends on the device. Please upgrade to a Xilinx.

Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. When I remove sector erasing at the start of this example code, software stops writing to SPI. So if you don’t need to overwrite data, you should be able to do byte writes.

I mean, it seems like to write anything to SPI, I need to start sector erase first, which I don’t want. But this example code does not work without erasing first.
