I am currently working with SPI flash memory W25Q128BV and using nuvoton processor of N9H30 series.
I have sample codes but not working correctly, but after erse only one time working properly.
I am having doubt in how to use SPI flash in general , so please give your suggestions.
I have following questions:
1.Can I write multiple times in SPI flash and read content without erasing?
2.Is there any way to erase only few bytes?
3.Can I read and write continuously to store data in multiple locations?
Thanks in Advance
None of these have anything to do with ARM - or even Nuvoton.
You need to go to the flash memory manufacturer for support with their products!
The flash memory neither knows nor cares what microcontroller you use.
Thanks sir your suggestion is right
