On the WROOM32 it will indeed be 4MB (= 32Mbit). Thanks. Does wroom32 have rtc crystal onboard? Data sheet says yes, but hdk module reference design doesn't have it. So reference design is intended for lowest cost modules like ai-thinker esp-3212, but wroom32 design is different? Thank you very much!

Edit: Ah, never mind, I can reproduce the problem. I'll see if I can fix it for future datasheets.

Thanks very much for your help!
