器件型号: AM6422
尊敬的 TI 专家:
我们使用 AM6422 定制板。 我想进行内联 ECC ddrss 测试。
2.并按照 https://git.ti.com/cgit/ti-u-boot/ti-u-boot/commit/?h=ti-u-boot-2023.04-next&id=af5609db6d1124e046cf623f80e00c3d27ff5fec 在 uboot 中编译 ddrss cmd。
当我进行 ddrss 测试时、1 位错误行为与发行说明中的描述相同。
=> ddrss ecc_err 82400000 1
Testing DDR ECC:
ECC test: Disabling DDR ECC ...
ECC test: addr 0x82400000, read data 0x0, written data 0x1, err pattern: 0x1, read after write data 0x1
ECC test: Enabled DDR ECC ...
ECC test: addr 0x82400000, read data 0x0
ECC test: DDR ECC 1-bit error
ECC test: 1-bit ECC err count: 1
ECC test: 1-bit error in [0x2400000:0x2400008]
=> ddrss ecc_err 82400000 1
Testing DDR ECC:
ECC test: Disabling DDR ECC ...
ECC test: addr 0x82400000, read data 0x1, written data 0x0, err pattern: 0x1, read after write data 0x0
ECC test: Enabled DDR ECC ...
ECC test: addr 0x82400000, read data 0x0
=>
但多位错误和多个单个位错误行为是不同的。
=> ddrss ecc_err 82400000 3
Testing DDR ECC:
ECC test: Disabling DDR ECC ...
ECC test: addr 0x82400000, read data 0x0, written data 0x3, err pattern: 0x3, read after write data 0x3
