The uploader doesn't care. It is your running firmware that complains about it being single core, and that is looking at the hardware. Maybe you can ask DigiKey if they have a lot number from what they sold you that you can match to what you received. Thank you for the explanation. I will contact D...

Just like any electronics, buy them from a reliable source, and you will get a reliable product. Mouser sells the MINI, and they list it as dual core. If they ship you single core (which they won't), they have a service department, and they will make it right. If you buy from Aliexpress, well, you ...

Hello all, I speced ESP32-MINI-1's for a custom PCB's due to size limitations and the need for dual core (which is stated in the associated data sheet). As I worked through a few troubleshooting issues, I realized that the MINI's were behaving (and recognized in Platformio) as single core - whereas ...

It sounds like platformio is not using the correct platform. Go into ~/.platformio/platforms and (re)move any esp32 platforms from there. Make sure you are using the platformio.ini as shown at https://github.com/Jason2866/esp32-arduino-lib-builder/blob/main_idf442/README.md This should make it so t...

I don't know enough about the Arduino side of things, but I can confirm this is a single-core issue. You probably aren't seeing the issue on the devboard because it has a newer MINI-1 module on it: at some point in production we changed the chip inside it to a dual-core one. Thanks for your reply E...

Hello all, I have been working on this issue for weeks and I could really use some help. I have a custom PCB prototype that I need to prove and okay for assembly ASAP and I am pulling my hair out over this. I am using a ESP32-MINI-1U-N4 due to space limitations. My custom board uses UART for uploadi...

Hello, I am transferring a ESP32 WROOM code to a C3. I updated all the pins to my new configuration (missed a few the first time) but when the C3 tries to boot, it gets stuck in a booting loop (see below). I did some research, and it looks like this is likely a pin mapping issue, I confirmed that al...

Hello, I am working on a custom PCB with a ESP32-C3FH4. I have only made 2 other custom PCB's and neither had a built in wifi antenna. I have read all the Espressif docs on the subject and I think I understand all the placement and noise reduction recommendations (option 3 in my case) but I would be...
