Multiple bootable SD cards on the SDHC1 controller

[dstepanov]

Hello!

Looks like it is possible to connect several SD cards to the same SD controller (SDHC1) on LX2160A SoC since it supports  ALL_SEND_CID broadcast command which allows to select SD card to operate with. Is it correct?

If yes, is it possible to do such a trick and to somehow select a proper boot source during boot process selecting one of SD cards connected to the same SDHC1 controller?

Thanks!

In theory, it is possible to do that. However, we have not done any validation on this. We do not have any board designed such way.
I would not mess around about the boot source as the BOOTROM is fixed in silicon.
