我买了Luckfox Lyra，烧录了BuildRoot文件夹内的SD卡update.img后，电脑就检测不到SD卡了，然后插入板子也没有反应

您好，请检查卡的规格是否是CLASS 10 ,同时检测读卡器是否正常，正常情况下SD卡会被识别到三个分区，如果确定读卡器是正常的有可能是SD卡读写过程中损坏了

I'm having the same issue, can't boot from the SD card now.

I was able to boot from the SD card at first, but after run for about a week, after a shutdown and restart, the device can't boot from SD anymore.

I think it's an Luckfox Lyra issue. I have tried 4 cards, including one of the latest Sandisk Extreme Pro U3 A2 card.

I was trying to do some debugging via the UART terminal. Nothing shows in there.

Hello, please check whether the device can be detected as a Maskrom device in RKDevTool when connecting it to the PC without the SD card inserted.
If it cannot be detected, it is possible that the Luckfox Lyra core board is damaged.

If it can be detected as a Maskrom device, try using RKDevTool to directly flash update.img (do not use SD_Firmware_Tool).
If the upgrade still fails, it is possible that the microSD card slot is damaged.
