Just saw this .. Thanks for your reply :-) We ended up writing our APP layer in Lua which lives in SPIFFS files. This way we can achieve much more granular OTA updates and smaller sizes (besides writing highlevel stuff in Lua is just so much nicer :-) Anyway regarding your bullets: The "system" part...

Thanks a million! This saved my day!!

Answering myself .. Found the solution: Do it the same way entrypoints from the internal ROM. Ie. w. PROVIDE() in .ld files. Fi. looking at tzset: > ag tzset esp-idf/components/newlib/include/time.h 82:_VOID _EXFUN(tzset, (_VOID)); 83:_VOID _EXFUN(_tzset_r, (struct _reent *)); esp-idf/components/esp...

Knock, knock ..
An offical stance on this would be really nice ..

Thanks for the reply. The plan was to set aside a big chunk of static ram for use with a custom allocator for Lua. As it turns out it is easier to just add this static chunk to the heap like so: uint8_t APPLuaHeapBuf[50 * 1024]; ... heap_caps_add_region((intptr_t) APPLuaHeapBuf, (intptr_t) (APPLuaHe...

Hello It looks like the available ram space is a roundly even split between heap and static allocations. Is there a way to increase one of these (at the cost of the other of course). Specifically, we do not need 187 KB heap space, but could do with a bit more than 180kB static allocations Cheers /Fl...

I am contemplating using the ESP32 for a Lora appliance ie. with very low network bandwidth. However it would be nice to still be able to update the main application part over the network (OTA). For this to work I would like to compile/link the lower layers of the SW into a separate partition and th...
