Dear all,
Our system has problem that a system reboots on an aging test to CSPI NOR Flash.
(aging test: Read/Write/Compare)
Our system uses i.MX6Solo.
The OS is based on fsl-yocto-3.10.53-1.1.0.tar(NXP BSP).
When reboot occurs, the following error is displayed by log.
We tested with ten systems, but only one has this problem.
When Watchdog timer is disabled, the system is not rebooted.
Only this 1 system has a CRC error of JFFS2
<<CRC error>>
jffs2: notice: (169) check_node_data: wrong data CRC in data node at 0x00395134: read 0x17320e73, calculated 0xb1a11cae.
We do not understand the cause of these errors.
Would you tell me the factor thought about?
What should we confirm to narrow down the cause of a problem?
May I have advice?
