Answers checklist.

• I have read the documentation ESP-IDF Programming Guide and the issue is not addressed there.
• I have updated my IDF branch (master or release) to the latest version and checked that the issue is present there.
• I have searched the issue tracker for a similar issue and not found a similar issue.

General issue report

a small bug has sneaked into the IDF v4.4.5, which leads to ugly warnings when building:

/esp-idf/components/soc/include/soc/soc_memory_types.h:140:25: warning: comparison of integer expressions of different signedness: 'intptr_t' {aka 'int'} and 'uint32_t' {aka 'unsigned int'} [-Wsign-compare]
     return ((intptr_t)p >= drom_start_addr && (intptr_t)p < SOC_DROM_HIGH);
             ~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~

Hello, @Andste82!

Thank you for sending the issue report. I was investigating this issue but unfortunately could not reproduce it on the ESP-IDF v4.4.5 tag.

We have suppressed all Wsign-compare warnings here - are you using any special C/CXX flags while compiling your example?

Hi @laukik-hase
thanks for you're response.

i use "vanilla" cmake in my projects because i don't like the "component magic" when using idf.py very well.
since the file with the warning is a header file, it is possible that my libs, with unsuppressed warnings, includes it.

i usually build my libs as follows:

target_compile_options(fancylib
	PRIVATE -Wall -Wextra -Wno-unused-parameter
)

the warning is not too bad, but since i want to handle every warning, and the headerfile is often included, the waning pops up very often during the build process.
