器件型号： AM62A7-Q1
您好、TI 专家
环境：
SoC：AM62A7-Q1
SDK：mcu_plus_sdk_am62ax_10_01_00_33
DDR：Micron 2GB 200b-z42m-automotive-lpddr4x-lpddr4.pdf
DDR 配置：1865MHz DDR_cfg (am62a7_2GB_1865_MT)。zip
问题：
启用内联 DDR ECC 后、我们进行了应力测试并遇到 ECC 错误中断、
禁用内联 DDR ECC 后、使用 memtester 时没有异常。 我想问一下、保证金是否不足、或时间是否过于激进？
DDR 启用过程：
1.在 SBL1 中设置 DDR ECC 配置
2.应用补丁
4、读取寄存器 0x0f300120 显示 ECC 已启用。

3.更新 u-boot-spl & u-boot & kernel 中的 dtb4、读取寄存器 0x0f300120 显示 ECC 已启用。
