Which SPI flash memory?

hello, I wanted to solder a SPI flash memory on my Rock Pi. Which SPI flash memory can I use? Is there a manual for this? What do I need to pay attention for? Thank you and sorry for my english


You can refer this page:


The footprint for the SPI flash is SOP8, the voltage level is 3.3V. The size should be larger than 4MB(32Mbit) to store the bootloader.
