Re: PS Ram Speed

char * rm = (char*)malloc(ramsize);
should be replaced by
char * rm = (char*)heap_caps_malloc(ramsize, MALLOC_CAP_SPIRAM);

Re: How do I use extram_bss in CMakeLists?

seem to be a Typo in Wiki.

.ext_ram.bss

seem to be the right one.

EXT_RAM_ATTR definition points to _SECTION_ATTR_IMPL(".ext_ram.bss", __COUNTER__)
