Having an Orange Pi Zero 512KB with legacy kernel (3.4.113).

What would be the right method to read and write data on the SPI FLASH?

The idea is not to boot from it, just to use it to store some variables that need to be independent of the SD card used for the operating system.

Thanks

I think It's a possible with SPI.
There is library for arduino.

https://github.com/Tamakichi/Arduino-W25Q64/tree/master/W25Q64
I think it can port to OPi/RPI

I ordered W25Q64.I'll try.

OpenWrt no longer fits in 4MB of flash, so current OpenWrt wouldn't even fit in a 2MB SPI.

I would love to at least have some form of bootload (chooser) available in the 2MB SPI, sometime similar to rEFIf or rEFInd to choose another boot device option. It would be nice if it also had the ability to download and flash base OS images directly from orangepi's site.

What I wouldnt give to have a debate with you about this.  You just say so many things that come from nowhere that Im fairly positive Id have a fair shot.  Your blog is terrific visually, I mean people wont be bored.  But others who can see past the videos and the layout wont be so impressed with your generic understanding of this subject.        jun88.bike

I have really learned some new things through your blog post. Also a thing to I have noticed is that normally, FSBO sellers can reject an individual. Remember, they’d prefer to never use your expert services. But if you maintain a steady, professional romance, offering help and remaining in contact for about four to five weeks, you will usually have the capacity to win a meeting. From there, a listing follows. Thanks        먹튀검증업체
