4.3.3 eMMC Read & Write

For this test, the AM62L EVM's on-board eMMC device is being written and read from.

To execute the write sequence:

root@am62lxx-evm:~# dd if=/dev/urandom of=<eMMC block device> bs=1M status=progress count=10000

To execute the read sequence:

root@am62lxx-evm:~# dd if=<eMMC block device> of=/dev/null bs=1M status=progress
