I have new toy, ESP-WROOM-32 module; it is ESP-WROOM-32 with UART CH9102X, it has micro-USB connector and module has 30 pins, 2 buttons (BOOT, EN) and two small LED diodes (RED for power, BLUE is connected to GPIO).
I flashed ESP-WROOM-32 module with firmware v1.6.3 for ESP32-devkit
I see errors in console during device boot, Invalid pin selected:
It can mine at hasharate about 50 kHps, Blue LED flashes (mining status)...
This is boot log from ESP-WROOM-32 module, it has UART cp210x, 30 pin, 2 buttons (EN, BOOT), 2 small LEDs.
It can mine, hashrate is about 50 kHps, blue LED blinks (mining status)...
It is interesting that errors related to GPIO pins are not there:
This is the firmware, all 4 files were flashed with esptool.py:

Firmware in git repository is not the same as firmware used by WebFlasher
Files used by WebFlasher are the same except the main firmware, that has different md5 checksum (and is significantly shorter):
$ md5sum 0x10000_firmware.bin
799c71b1b0f2292b67e77bac909997b6 0x10000_firmware.bin
$ ls -l 0x10000_firmware.bin

I miss explanation why I was flashing firmware from git repository. I have two modules with ESP-WROOM-32 and UART CH9102X. They look the same, they were bough with the same order. It is interesting, that MAC addresses are very different, like devices from different manufacturers. Other difference is that one device cannot be flashed with WebFlasher (I tried many times); that is why I start to use esptool.py flasher and files from git repository. I cannot explain, what is the difference, but one of modules just cannot be flashed with WebFlasher. The modules looks like the same device, no visible difference...
I am not sure why but maybe that may git was not updated. I missed one file.
File 0x10000_firmware_v1.6.3.bin is the same as 0x10000_firmware.bin from the WebFlasher. Fiie 0x10000_firmware.bin in the git repository is different and it reports errors to the serial console...

UPDATE. I updated firmware, I used esptool.py and flashed 4 images from github reporistory. I see errors after update:

When I flash firmware from the web, I do not see the error:
