Jetson 软件
JetPack Linux 32.7.6
Problem Description:
Physical Connection: Nano USB port → USB adapter card → SSD
Timeline:
‘t0: Normal → t1: R/W error → t2: reboot → t3: SSD not detected → t4: reboot → t5: SSD not detected → t6: power cycle → SSD detected normally’
t0: SSD read/write normal
t1: SSD read/write error

t2: System reboot
t3: SSD not detected after system boot
t4: Reboot again
t5: SSD still not detected
Attached Log 1:

The above log covers the kernel logs from t1 to t5.
t6: Power cycle (power off, then power on again) → SSD is detected normally
Attached Log 2:

t2: reboot系统
t3: 系统启动后无法识别ssd
t4: reboot
t5: 仍无法识别ssd
现象2-1 读写报错_软重启未报错未识别ssd.log (194.2 KB)
以上是t1~ t5的内核日志
t6:断电，再重新上电，可以正常识别ssd
现象2-2 断电才能重启识别ssd.log (92.9 KB)
以上是t6的内核日志。
