When booting from NAND fails, boot9 will then attempt to boot from Wifi SPI-flash(this only triggers when the wifi module hw is properly accessible/connected, which is normally the case). The base offset for spiflash FIRM is 0x400. Note that this region is write-protected by the spiflash.

When booting from NAND fails, boot9 will then attempt to boot from Wifi SPI-flash(this only triggers when the wifi module hw is properly accessible/connected, which is normally the case). The base offset for spiflash FIRM is 0x400. Note that this region(all data prior to offset 0x1F300) is write-protected by the spiflash(not writable from 3DS-mode / DS-mode).
For non-NAND booting, NCSD / FIRM-backup is not used.
