Re: S3 BootLoop Revisited

After much digging, I should know better. Something similar has bitten me before. ESP32-S3-WROOM-2-D3N32R8V ESP32-S3-WROOM-2-M0N32R8V The WROOM-2 still have problems with a few things. The biggest is flashing the image, so while I could flash an image via UART, I could not do it via OTA. Additionall...

Re: S3 BootLoop Revisited

Hmm, this is frustrating. I just pinned it to the 5.1.0 version and it still bootloops.

S3 BootLoop Revisited

ESP32-S3-DevKitC-1 I am working on a small web server project with OTA update capability. I'm trying to use the official packages, and am not sure if I'm not doing something right, or perhaps the S3 isn't supported like I think it should be. My platformio.ini file: [env:esp32-s3-devkitc-1] platform ...

Re: Boot Loop on ESP32-S3

Changing the ldscript from esp32s3_out.ld to esp32_out.ld seems to be a fix, but not the fix. It's like there is residual information from load to load.

Re: Boot Loop on ESP32-S3

This is interesting. The stock esp32-s3-devkitc-1.json doesn't work, whereas it used to. Following your posts, I used this file: https://github.com/platformio/platform-espressif32/blob/develop/boards/esp32s3camlcd.json#L5 I flashed, and the program ran correctly as expected. I then started picking o...

Re: Boot Loop on ESP32-S3

Thanks for the reply. I have two boards, D3N32R8V One is working, the other not. I'm planning on searching for a way to read the eFuse, to see if that's the issue. I'm also suspicious of my partitions. I'm fairly new to ESP32, and I don't know if I even need partitions unless I'm doing NVRAM. So, I'...

Boot Loop on ESP32-S3

In troubleshooting a USB problem, I've somehow stumbled into a condition that I don't know how to recover from. I'm using an ESP32-S3-DevKitC bare, nothing connected but a USB cable to UART connector. VSCode, PlatformIO, Arduino framework. After flashing, I get the following infinite loop on the USB...

ESP32-S3 delicate USB on GPIO19 and GPIO21?

In developing for the S3, I'm using the ESP32-S3-devkitC. Out of ten units, I've damaged about two of them now. It looks like I am destroying the native USB drivers on the chip at GPIO19 and 21, not the CP210 UART. I can still program through the CP210, so the processor is still alive, but my board ...

Re: esp32-C3 usb serial/jtag for flashing AND serial console output

I'm using the S3, so these options may help: in your platformio.ini: build_flags= -DARDUINO_USB_MODE=1 -DSERIALCONS=USBSerial Depending on my target SERIALCONS changes, but in my code, I use SERIALCONS and place I would normally use Serial. I'm also including these, but not sure if they are needed f...
