SPI NAND Interference

Some Luckfox Lyra boards include SPI NAND flash memory. The RK3506G2 boot ROM always tries NAND first, so if your board has NAND with any firmware on it, the boot ROM will ignore your SD card completely.

Quick Check: - Lyra models with "SPI NAND" or "Lyra B" or "Lyra Plus" have NAND - Check your purchase specifications - If unsure, try booting - if SD card is ignored, you likely have NAND

Solution: You must erase the SPI NAND flash. See the comprehensive SPI NAND Erase Guide for detailed step-by-step instructions covering:

  • Windows method (RKDevTool)
  • Linux method (upgrade_tool)
  • MaskRom mode recovery
  • Troubleshooting failed erases

Critical: Data Loss

Erasing SPI NAND will permanently delete all data on the NAND flash. This cannot be undone. Ensure you understand the implications before proceeding.
