Can find the Ubuntu_Luckfox_Pico_Ultra_W_SPI_NAND ,Ubuntu_Luckfox_Pico_Ultra_W_FLASH,can share?
Looking for Ubuntu_Luckfox_Pico_Ultra_W_FLASH
The Luckfox_Pico_Ultra does not have a reserved SPI_NAND interface, and Ubuntu does not support Flash (due to insufficient space and lack of file system support).
