Hacking need help: switch lite always can't boot into emunand

[jzhoulon]

Hi,
I have a switch lite with SX core. I downgrade it from 11.0.1 -> 11.0 through atmosphere. And then I create emunand with boot3.1.0. Here is the situation:
1. I can boot in to OFW normally
2. direct boot the machine or click CFW with emunand enabled, It ways boot in to Original Sysnand (without SXOS enabled), but have a small chance it can boot into emunand successfuly.
3. I can always boot into SXOS in OFW(disable emunand) successfuly.
And I have tried:
1. format sd card as Fat32 and exfat , nothing different.
2. change sd card(changed 5 sd card with different vendor and size, nothing different)
3. create emunand in file or hidden parition: nothing different.
Does any one knows what happend? will it have issue in hardware? Thanks very much

How do you know if its booting into sysMMC or emuMMC?

have you checked if your SD Card is getting recognized correctly when booting into Sysnand?
Might be SD reader...
