esp32_flash_loader's Issues

Analysis off by 1 byte

When performing analysis, not enough padding is used, i.e. for the function at 400d43fc analysis start at 0x400d43f
Any way to fix this?
I also want to remove the label and perform reanalysis at the correct address, but I cannot define a function on Data.
Any tips on how to do this in ghidra?

This is the incorrect analysis as the first 0 should have been ignored.
If analysis is performed at address 400d43fc, not 400d43fb then things make more sense.

ESP32 specific language spec missing

Hello, Where is it possible to find the ESP32 specific language spec?
I like the esp32_rom.elf loading but cannot find the ESP32 specific spec for ghidra.
