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’: When I remove sector erasing at the start of this example code, software stops writing to SPI. I mean, it seems like to write anything to SPI, I need to start sector erase first, which I don’t want. Is this a j25p64 piece of SPI code?

We have detected your current browser version is not the latest one. But this example code does not work without erasing first. Is there any solution? Is the response I have obtained is it right? So my question is “Is the response I have obtained is it m25pp64 This Wikipedia page explains flash memory fairly well.
It’s the definitive way to be sure. Actually example code runs great as well. Non-volatile datashret that is byte erasable. Sign up or log in Sign up using Google. The response is wrong. So, without being able to erase, a write is not very useful. I can use Impact to write and read the code successfully, it works great.
Does your SPI code work with any other devices?
Things to check since you have not provided any information: Things to check since you have not provided any information:. As Austin said, “flash” is not byte erasable, although if already erased, it is byte writable for “NOR”. 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. Have you got the SPI module configured correctly for phase and polarity? I read the datasheet as well, but I couldnt find a solution for automatic erasing only the data I overwrite.
Did you remember to send a dummy byte after the RDSR command so that the device would send the status register value? Does the MSP read that value or a different one?

Auto-suggest helps you quickly narrow down your search results by suggesting possible datasgeet as you type.
You are sometimes better first of all trying to read the device ID dqtasheet than the status register for a new piece of code. There is no single byte erase. I store configuration data on the SPI, I cannot erase all the data inside the whole sector.
