我启用了CoreDump，串口输出分区表如下：
I (79) boot: Chip Revision: 1
I (80) boot_comm: chip revision: 1, min. bootloader chip revision: 0
I (41) boot: ESP-IDF v3.3.1 2nd stage bootloader
I (41) boot: compile time 09:32:10
I (41) boot: Enabling RNG early entropy source...
I (45) boot: SPI Speed : 26.7MHz
I (50) boot: SPI Mode : DIO
I (54) boot: SPI Flash Size : 4MB
I (58) boot: Partition Table:
I (61) boot: ## Label Usage Type ST Offset Length
I (69) boot: 0 nvs WiFi data 01 02 00009000 00004000
I (76) boot: 1 otadata OTA data 01 00 0000d000 00002000
I (84) boot: 2 phy_init RF data 01 01 0000f000 00001000
I (91) boot: 3 factory factory app 00 00 00010000 00100000
I (98) boot: 4 coredump Unknown data 01 03 00110000 00010000
I (106) boot: 5 ota_0 OTA app 00 10 00120000 00100000
I (113) boot: 6 ota_1 OTA app 00 11 00220000 00100000
I (121) boot: End of partition table
I (125) boot: Defaulting to factory image
随后串口打印：
I (295) esp_core_dump_flash: Init core dump to flash
I (301) esp_core_dump_flash: Found partition 'coredump' @ 110000 65536 bytes
E (308) esp_core_dump_common: Failed to mmap core dump data (260)!
该如何解决呢？谢谢。
