Summary0006564: aStoneMX8MP: SDHC eMMC read/write speed is low
DescriptionUsing the tool CrystalDiskMark, you can measure the read and write speeds of the eMMC. The speeds are typically around ±40 MB/s. This is due to the fact that the voltage level of the lines is set to 3.3V. To achieve faster read and write speeds, the voltage needs to be adjusted to 1.8V.

This can be done by modifying the "Regulator1V8Exist" parameter in the ACPI table in the dsdt-sdhc.asl file.
