Hello,
Is there any way to physically extract the emmc memory chip and boot successfully the Angstrom linux distribution just/only from microSD card ?
Do you have any advice for this problem ?
Thank you in advance.
are you aware that the eMMC chip is a ball-grid package? It’s possible to unsolder it, of course, with skill and hot-air repair station. I am not sure if the boot sequence stops on failing to detect the eMMC presence ; I suspect it’s possible to force the SD boot using the usual keypresses that work with eMMC present.
Yes, of course, with hot-air and with very much attention. I don’t know exactly if I need to make any changes to the board schematics, to boot without problems from sd card.
