Hi Forum,

The default eMMC chip on DragonBoard410c is now out of production. We couldn’t find a compatible replacement. My question is if we replace it with a different/larger eMMC chip, how to change the software/parameters to boot it?

My understanding is that with larger size of NAND flash and DDR, we have to modify sbl1.mbn to match the new chip, But the source code is not available. Is it possible to provide additional list of supported eMMC chips? Or any suggestions are highly appreciated!
