Problem Description

I created a nvs partition hardware of 0x1000
Partition table binary generated. Contents:
*******************************************************************************

# Espressif ESP32 Partition Table

nvs,data,nvs,0x9000,16K,
otadata,data,ota,0xd000,8K,

*******************************************************************************

I created a csv file with
key,type,encoding,value
gpio_space,namespace,,
PIN_NUM_MISO,data,u8,19
PIN_NUM_MOSI,data,u8,23
PIN_NUM_CLK,data,u8,18

When i want to create a bin i have this error:
$ python C:/msys32/home/jp/esp/esp-idf/components/nvs_flash/nvs_partition_generator/nvs_partition_gen.py standard.csv standard.bin 4KB
Size parameter is insufficient.

With 8KB partition (0x2000) it works.
Why a 4KB size is not accepted?

Nvs needs at least 2 sectors
