Part Number: BEAGLEBK
Tool/software: Linux
Hello,
The BeagleBone Black has GPIO1_20 brought out to eMMC_RSTn. In our design we need to use a different GPIO, but I can't find any device tree configuration for the eMMC_RSTn or any driver support in ./drivers/mmc/host/omap_hsmmc.c - which now that I think about it doesn't make any sense since the eMMC would have to be initialized for the kernel or device tree to be loaded.
Is this GPIO1_20 actually used to pulse a reset to the eMMC, or does it just hold the eMMC in reset until the Boot ROM loads? In that case, can it be moved to a different GPIO or tied to SYS_RESETn?
