Wifi Firmware partition does not work in secure boot mode?

[richard9999999999]

I have application which uses "Wifi Firmware" partition functionality:

pico_use_wifi_firmware_partition(efis NO_EMBEDDED_PT)

The partition definition is as follows:

 {
		"name": "Wi-Fi Firmware",
		"id": "0x776966696669726d",
		"start": "3500k",
		"size": "240K",
		"families": ["data"],
		"permissions": {
		  "secure": "rw",
		  "nonsecure": "rw",
		  "bootloader": "rw"
		},
		"link": ["owner", 0],
		"ignored_during_riscv_boot": true,
		"no_reboot_on_uf2_download": true
	  },

It works well but not in secure boot mode. The same firmware works on module without secure boot (works including Bluetooth functionality), but it doesn't work on module with secure boot enabled, it fails in partition check:

            uint32_t* workarea = malloc(0x1000);
            picked_p = rom_pick_ab_partition_during_update(workarea, 0x1000, picked_p);
            free(workarea);
            #ifdef __riscv
                // Reset bootrom stack
                rom_set_bootrom_stack(&stack);
                free(stack.base);
            #endif

            if (picked_p < 0) {
                if (picked_p == BOOTROM_ERROR_NOT_FOUND) {
                    CYW43_DEBUG("Chosen CYW43 firmware partition was not verified\n");

picked_p is BOOTROM_ERROR_NOT_FOUND

I found I have to add:

"ignored_during_arm_boot": true,

So I guess the problem is only that I didn't have wifi firmware binary signed..
