eMMC Scripts #49

Closed gbalke closed 3 years ago

gbalke commented 3 years ago

These scripts build and load the necessary boot files to be able to run OVC off the integrated eMMC. This way there's no need for more than one SD card to program many devices!

I just ran a quick benchmark using hdparm:

# SD Card
(arm64-debian)root@zynq:~# hdparm -Tt /dev/mmcblk1p2

/dev/mmcblk1p2:
 Timing cached reads:   2072 MB in  2.00 seconds = 1036.13 MB/sec
 Timing buffered disk reads:  68 MB in  3.01 seconds =  22.57 MB/sec

# eMMC
(arm64-debian)root@zynq:~# hdparm -Tt /dev/mmcblk0p2

/dev/mmcblk0p2:
 Timing cached reads:   2318 MB in  2.00 seconds = 1159.09 MB/sec
 Timing buffered disk reads: 528 MB in  3.00 seconds = 175.85 MB/sec
