I have implemented ARM M4 to a SoC, but it's unfortunate that there's no memory.
Is there any chance that I can use MicroSD card as memory?
If it's possible, can someone show me how?
To be specific, I have QUAD-SPI (ARM - Flash memeroy) pins on PCB connected to a MicroSD Memory Card Connector attached with an SD Card that I am intend to use as Flash for ARM.
What should I write to the SD card? and how?
You can use spi flash as Winbond 25q64.
