器件型号:TDA4VM
Thread 中讨论的其他器件:CSD

工具与软件:

1、我们进行了16小时的高温和低温压力测试,发现我们的睡眠文件在压力测试后损坏

root@j721e-evm:~# ls -l /bin/
[ 7052.671361] EXT4-fs error (device mmcblk0p2): ext4_lookup:1851: inode #39: comm ls: iget: bad extended attribute block 141733921779
ls: cannot access '/bin/sleep': Structure needs cleaning

2 μ s 与、的睡眠文件 MD5相比、发现了更改

3、log

4、eMMC 压力测试出现问题后、读取和写入无异常

    您好、Kong:

    有多少个样本显示此行为?

    您是否在高温条件下对 eMMC 进行过任何读取/写入操作?

    什么是数据睡眠文件?

    您正在进行什么样的压力测试?

    此致
