Hello,
How do I know if I have the right card as shown here
https://olimex.wordpress.com/tag/sata/
to make olinuxino-sd-to-sata work
On my card I read A20 olinuxino micro rev F.
How are complements like -e16Gs16M indicated ?
Hint: my card was bought about 6 or 8 years ago.
You need to inspect what is placed empirically - compare what you see with the hardware revision of your board but your board has no SPI flash unfortunately. SPI flash was being placed in newer revisions. Lack of SPI might be is a problem when booting from some mediums but I believe it should not affect and it also affects the ability to boot from SATA disk.
It requires some software fixes to enable it.
