The protected kernel linker (kernel-space.ld) placed the octal (OPI) flash bring-up helpers -- esp_rom_spiflash / esp_rom_opiflash_*, spi_flash_oct_flash_init, mmu_hal, mspi_timing_*, bootloader_flash*, efuse_hal/efuse_utility, esp_mmu_map and esp32s3_spi_timing -- in mapped flash. During configure_cpu_caches() / spi_flash_init_chip_state() in __start these run while the flash mapping is being reconfigured, which faults (illegal instruction) on octal-flash modules such as the ESP32-S3-WROOM-2. Quad-flash parts never exercise the OPI path, so the problem was latent. Place those functions in .iram0.text (mirroring the flat sections script) so they are safe to execute during flash reconfiguration.
