2 分区表 #
使用 idf.py partition-table 来显示分区表内容。
使用 gen_esp32part.py 工具来将 CSV 分区表转换为烧写到 FLASH 的 bin 格式。
# Erase partition with name 'storage'
parttool.py --port "/dev/ttyUSB1" erase_partition --partition-name=storage
# Read partition with type 'data' and subtype 'spiffs' and save to file 'spiffs.bin'
parttool.py --port "/dev/ttyUSB1" read_partition --partition-type=data --partition-subtype=spiffs --output "spiffs.bin"
# Write to partition 'factory' the contents of a file named 'factory.bin'
parttool.py --port "/dev/ttyUSB1" write_partition --partition-name=factory --input "factory.bin"
# Print the size of default boot partition
parttool.py --port "/dev/ttyUSB1" get_partition_info --partition-boot-default --info size
