Hi guys , I've face a problem with a sudden dead emmc on a corona motherboard , I had spare emmc's from another devices liying around (and I didn't want to buy and wait for them to arrive) and decided to try what would happen and after facing various errors finally was able to make it work , now console boots fine and recognizes 32gb as internal memory .I guess it supports any size of emmc . Console has rgh installed of course .
