Arduino ide - which board for DFROBOT ESP32-S2-DevKitM-1

Support
1

I just purchased a DFROBOT ESP32-S2-DevKitM-1 Development board. I setup as per Arduino IDE Setup | Adafruit Metro ESP32-S2 | Adafruit Learning System.
I am using the arduino ide version 2.0.0 rc8 and selected Adafruit Metro ESP32-S2 as the board.

I can download code but it does not run:I have tried blink and wifiscan

I see the following in the serial monitor.
…
14:41:07.946 → e[0;32mI (668) boot: Loaded app from partition at offset 0x10000e[0m
14:41:07.946 → e[0;32mI (668) boot: Disabling RNG early entropy source…e[0m
14:41:07.984 → E (695) psram: PSRAM ID read error: 0x00ffffff

I also tried “ESP32S2 Dev Module” as the board. The wifiscan program runs but I see the following in the serial monitor:

15:1:22.515 → SHA-256 comparison failed:
15:1:22.515 → Calculated: 8dce998efc3eb6dc43f3799a489dbcfbd5ada9828beadf71017c05c4a8d32bc3
15:1:22.515 → Expected: ffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff
15:1:22.515 → Attempting to boot anyway…

So this does not seem right either. What board should I select?

According to Adafruit’s guideline, we’re supposed to select Adafruit Metro ESP32-S2. But it failed in your case. May be a bad board. Let’s see what the Core team says.

I have copied the serial monitor output from loading the wifiscan program and the output from reset. I note that the image segments reported by load and reset are significantly different. This seems weird but I’m a complete novice with this device. The program does not run after either load or reset. This is using the Adafruit Metro ESP32-S2 board in the arduino ide.

Hi Russell,

Sorry for the delay in getting back to you!

Starting from the base page of Arduino IDE nagivate to Files > Preferences.

Then add https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json to the ‘Additional boards manager’

Then head to Tools > Board > Boards Manager > And search ‘esp32’
Wait for the menu to load and select the latest version, you’ll have all of the latest dev-kits available in the menu there!

Sorry for leading you astray with the Adafruit Metro board, that board features PSRAM so it wont compile correctly.

Hi Liam,
Sorry, I didn’t see your post because Outlook assigned it to junk.
I have been using “ESP32S2 Dev Module” as the board and ignoring the SHA warning.
Everything seems to be working as expected. So I presume that my selection is close enough.
