Security Bit

For ATSAMD5x/E5x systems that make use of the “Security Bit” of the ATSAMD5x/E5x SoC, custom openocd commands may be required in the YAML test plan.

Example: Set ATSAMD5x/E5x Security Bit

title: "Set ATSAMD5x/E5x Security Bit"
suite:
- title: DUT power
  steps:
  - command: power off
  - command: ground 1
  - command: sleepms 50
  - command: power 3V3 on
  - command: sleepms 500
- title: Enable security on SAMD5x/E5x
  steps:
  - command: openocd ATSAME5
    with:
    - ftdi_init_samd_cold_plug
    - init
    - reset halt
    - atsame5 set-security enable
    - exit

Example: Erase secured ATSMD5x/E5x (including user page)

title: "Erase secured ATSAMD5x/E5x"
suite:
- title: DUT power
  steps:
  - command: power off
  - command: ground 1
  - command: sleepms 50
  - command: power 3V3 on
  - command: sleepms 500
- title: Disable security and erase SAMD5x/E5x
  steps:
  - command: openocd ATSAME5
    with:
      - ftdi_init_samd_cold_plug
      - init
      - atsame5 chip-erase-secured

User Page

For Microchip SAMD program targets that require modifications to the “Smart EEPROM” user page during production programming, custom openocd commands may be required in the YAML test plan.

Example: Write ATSAMD5x/E5x User Page

- title: "Write ATSAMD5x/ATSAME5x User Page"
  steps:
  - command: openocd ATSAME5
  - with:
    - init
    - reset halt
    # Write 2 to SEESBLK and 4 to SEEPSZ fields but leave other
    # bits unchanged (setup SmartEEPROM of virtual size 8192
    # bytes)
    - atsame5 userpage 0x4200000000 0x7f00000000
    - exit
