Memory and Flash-Test

  • RAM:

    - Our NBoot usually contains a small undocumented RAM test feature. Simply type 't'.
    - U-Boot has a built-in RAM-Test by calling mtest
    - You can add the "memtester" package to BuildRoot to have a RAM test available in Linux at runtime


    - In U-Boot, you can call 'nand bad' to show the bad block table

    Other than that there is no additional test. Usually the NAND is checked when writing data and blocks are marked bad when erasing or writing to them fails. So NAND is actually tested by using it.
