KeyError: '.flash.rodata'

Similar to #8 I get this error

C:\Desktop\badge\esp\esp32_image_parser>python esp32_image_parser.py create_elf new.bin -partition app0 -output app0.elf
Dumping partition 'app0' to app0_out.bin

any ideas?

Are you using firmware from an ESP32-S3 or S2? I'm having same issue with ESP32-S3.

Output below seems to indicate that we are not dealing with an esp32

Warning: Unexpected chip ID in image. Expected 0 but value was 9. Is this image for a different chip model?

I think this repo is getting out of date with all the newer chips.

I changed this line

diff --git a/esp32_image_parser.py b/esp32_image_parser.py
index 6503cf7..ef487c4 100755
--- a/esp32_image_parser.py
+++ b/esp32_image_parser.py

     return p_flags
 
 def image2elf(filename, output_file, verbose=False):
-    image = LoadFirmwareImage('esp32', filename)
+    image = LoadFirmwareImage('esp32s3', filename)
 
     # parse image name
     # e.g. 'image.bin' turns to 'image'

and now I get different output and chip ID warning is gone

Looking into #9 #11 and #17

[rcorsi]

I got idea to change the chip ID in #12

I think this fork might have what is needed to solve the problem https://github.com/precurse/esp32_image_parser

Look in the extra 2 commits.
