Tool/software: Linux
When we turned on the product after turning it off, it didn't start.
I have checked the serial output of the product. It stopped with a bad CRC error.
There may be hardware failure (NAND failure) or software failure (setting error and U-Boot bug).
・In this version, do bugs cause any symptoms?
・Can you determine the countermeasure from the log?e?
※NANDは以下製品から変更しています。MT29F2G08AADWP-D→MT29F2G08ABAEAWP:E
変更前製品では、この症状の報告はありませんでした。
※ NAND has been changed from the following products.
MT29F2G08AADWP-D → MT29F2G08ABAEAWP: E
There were no reports of this symptom before changing the NAND.
