Show partitions says reading partitions and then exits

[mpsOxygen]

Hello,

I am trying to dump a esp32 binary image from a Xiaomi IR remote, unfortunately it isn't working.

Any ideas why this is happening?

(venv) [user@fedora esp32_image_parser-master]$ ./esp32_image_parser.py show_partitions chuangmi.remote_2.0.6_0006.v2.bin
reading partition table...
(venv) [user@fedora esp32_image_parser-master]$

From what I can tell my magic isn't matching what is in the script:

>>> f.seek(0x8000)
32768
>>> magic = f.read(2)
>>> magic
b'av'

The images is a valid esp32 bin:

(venv) [user@fedora irtest]$ esptool --chip esp32 image_info chuangmi.remote_2.0.6_0006.v2.bin

For me, even #3 does not help:

may be you have the ESP32 RISC-V based #12

Which image are you using? If you don't have the device at hand, you can reconstruct the image in the flash with dd using the application's binary, bootloader/bootloader.bin, and partition_table/partition-table.bin.

In my case, it was returning nothing because I was trying to show_partitions on the app_0.bin dump, not on the full flash dump.
