3.3 Read SSD
Select '2' to send Read command to NVMe PCIe SSD. Three inputs are required for this
menu.
1) Start LBA: Input start address of SSD in sector unit. The input can be decimal unit or add
"0x" as a prefix for hexadecimal unit.
2) Sector Count: Input total transfer size in sector unit. The input can be decimal unit or add
"0x" as a prefix for hexadecimal unit.
3) Test pattern: Select test pattern to verify data from SSD. Test pattern must be matched
with the test pattern which is used during write test. Five types can be selected, i.e. 32-bit
increment, 32-bit decrement, all 0, all 1, and 32-bit LFSR counter.
Similar to write test if all inputs are valid, test system will read data from SSD. Test
performance, total size, and total time usage are displayed after end of transfer. "Invalid
input" will be displayed if some inputs are out-of-range.
Figure 3-8 and Figure 3-9 show the error message when data verification is failed. "Verify
fail" message is displayed with error address, expected data, and read data. User can press
keyboard to cancel read operation or wait until all read process complete.
"RESET" button must be pressed to restart the system when user cancels the operation.
