Adding SPI Flash to A64-OLinuXino-1Ge16GW

[tbultel]

Hi,

I would like to add a SPI flash on my A64-OLinuXino-1Ge16GW, to put uboot on it.
I found this:

When it is soldered, do I have something else to do, to have the CPU loading
uboot from it ?
Thanks !

Yeah, this memory should work. But check the schematic there are some other components to be placed also.

Thanks, I will doublechek the missing parts on the schematics.
I am customed to MTD devices, so I think it should even be possible
to flash it from Linux instead of from u-boot.

My question was rather:
How will the board boot on it ? In the other manufacturer boards I have been
working on in the past, there was usually dip switches to select the boot from either SD, emmc, and SPI flash.
How does this work with the A64 ?

Thanks !

Determined by the A64 internal BROM.

There is priority order. SD > eMMC > SPI flash > USB. The first place that the boot process finds proper boot sequence is the selected one. Read here:
