If a certain memory structure is only addressed in 32-bit units, for example an array of ints or pointers, it can be useful to allocate it with the MALLOC_CAP_32BIT flag. This also allows the allocator to give out IRAM memory; something which it can’t do for a normal malloc() call. This can help to...

Link the application and examine the elf file: xtensa-esp32-elf-objdump -t -j .dram0.bss Hi, We have also faced this type of issue while adding some external source to compile int...
