The response is wrong.
I store configuration data on the SPI, I cannot erase all the data inside the whole sector. But this example code does not work without erasing first. This Wikipedia page explains flash memory fairly well. The reason for that is the device ID will never change, whereas the status register might change although that depends on the device. There is no single byte erase. Sign up or log in Sign up using Google.
Do you see a response from the device on an oscilloscope? We have detected your current browser version is not the latest one.
Is the response I have obtained is it right? Datasneet mean, it seems like to write anything to SPI, I need to start sector erase first, which I don’t want. All forum topics Previous Topic Next Topic. Did you forget to assert the chip select line? Abhay 30 2 8.

It’s the definitive way to be sure. As Austin said, “flash” is not byte erasable, ddatasheet if already erased, it is byte writable for “NOR”. Post as a guest Name.

So, without being able to erase, a write is not very useful. Have you got the SPI module configured correctly for phase and polarity? So if you don’t need to overwrite data, you should be able to do byte writes. I can use Impact to write and read the code successfully, it works great.
Non-volatile memory that is byte erasable. So my question is “Is the response I have obtained is it right? Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type.
Is there any solution? 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 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’: 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?
