According to references the EP32-WROOM-32D should have a DOWD version of the chip. Both v1.2 and v3.1dev of esptool.py return DOWDQ6. The boards are from Aliexpress marked ESP32_Devkitc_v4 Az-Delivery. The Az-delivery.de site says that they have 2 cores which means they really are not a 32D(DOWD).
Does esptool.py not report the correct chip revision?
ESP32-WROOM-32D, DOWDQ6 or DOWD

Re: ESP32-WROOM-32D, DOWDQ6 or DOWD
If you ran that esptool command on a ESP32-WROOM-32D or 32U then you have the same chip revision as I do. Both the ESP datasheet and Wikipedia say that it should have a DOWD chip.
Also, comments about the number of cores in those versions do not seem consistent.
Thanks for checking.
