I don't think I need the industrial temperature range but am considering ordering a A64-OLinuXino-2Ge8G-IND for the 2GiB RAM (I don't need WiFi either). "-e8G" suggests it uses 8GiB eMMC flash but that's not entirely clear to me from the product page (https://www.olimex.com/Products/OLinuXino/A64/A64-OLinuXino/open-source-hardware), could you please confirm that's the case?
I'd like to boot from that flash chip and also use UEXT, and from the schematics (https://raw.githubusercontent.com/OLIMEX/OLINUXINO/master/HARDWARE/A64-OLinuXino/1.%20Latest%20hardware%20revision/A64-OLinuXino%20hardware%20revision%20E/A64-OlinuXino_Rev_E.pdf) I understand that's only possible for eMMC. Also, I'd like all GPIO pins to be available, and as far I understand PC4 and PC7 are not available when a NAND flash chip is installed. Is UEXT usable on then A64-OLinuXino-2Ge8G-IND when booting from the 8GiB flash chip, and are all its GPIO pins available?
Yes, "-e8-" means 8GB eMMC memory.
Yes, using latest Olimage Linux images you can boot from the eMMC. Yes, all UEXT pins are available and also a lot of the pins at the GPIO1 header - notice that both UEXT and GPIO1 come without connector - these are just pinholes.

Awesome, thank you for confirming!
