issues VS ezDV

The root cause seems to be https://github.com/esphome/issues/issues/3904. How do people get the idea to publish such shit?

For the record, this is my display's YAML configuration (please, bear in mind that the rest of the IDs and components are also present. You can get a full copy of my YAML file in here):

https://github.com/esphome/issues/issues/2646 suggests that ESP-IDF changed a couple years ago, try this tweak

I have tried PlatformIO and Arduino IDE with various libraries from the bog standard ESP32 devkit to obscure packages on github: https://github.com/Murkas94/arduino-esp32-solo/tree/version_update/2_0_9 and here: https://github.com/lbernstone/arduino-esp32-solo along with something made by Tasmota. I went spelunking through various github issues and stackoverflow questions based on google searches and still can't seem to find a configuration that works.

Everything I'm reading says that if you tried to flash a 4MB image onto a 1MB ESP, that you'd receive this error. In this thread the user was encountering the error and it turned out what they thought was a 16MB ESP was actually a 4MB and it refused to flash it. So I'm questioning your claim that you successfully flashed a 4MB firmware onto a 1MB ESP.

I found this: https://github.com/esphome/issues/issues/2634

Is my mistake trying to use a docker container? There is an issue against this. https://github.com/esphome/issues/issues/3357 Which actually list some other boards that are also having the same type of issue. /u/jesserockz has https://github.com/esphome/esphome/pull/3564 . Is there a way perhaps that we could just get the board list updated https://github.com/esphome/esphome/pull/3564/commits/03f6cd54abec53e00ddc5d5a3ab42163f10be26a ?

Okay, thishelped

I've been working on a handheld device that interfaces with a ham radio and effectively acts as a modem for HF digital voice (specifically FreeDV). It's basically a ESP32S3 combined with a TI TLV320 codec chip and some C++ code to link it all together (with HTML/CSS/JS for the configuration Web interface). It even has enough horsepower to communicate with a few radios that can trigger TX/RX and send/receive audio over Wi-Fi. :)

My ESP32 based FreeDV solution uses the TLV320AIC3254 codec chip and I'm satisfied with the audio quality. I'm also not using anywhere near all of its functionality (for instance, there are a couple of miniDSP cores in there too). FWIW, so far JLCPCB hasn't had problems getting stock when I order prototype runs.

Anyway, the photo is my oscilloscope connected to a tinyCurrent, which itself has 3.7V going through it to the battery header on the board I'm working on. Right now I'm having the ULP execute every 100ms to check the state of a button press, with it being held down for more than a second triggering booting the main processor. While I seem to measure in the ~45uA range with a multimeter, there are definitely peaks of multi-hundred uA while the ULP is running.

Current full schematic

I use PSRAM for my audio related project and it seems to work well enough. Granted, I'm using an ESP32-S3 with a TLV320 audio codec chip, so YMMV if you try to use the built in ADC/DAC of the original ESP32 or something.

Source code and schematics are at https://github.com/tmiw/ezDV. Along with eliminating the need for a separate ESP32 dev board (thanks JLCPCB for finally getting the S3 in stock!) there's also support for battery charging and measurement. Surprisingly I got the USB connection right-ish on my first try (to the limits of my test capability here at home, anyway); my Mac seems to report only 500mA max current in System Information (despite having the correct USB-C resistors for 5V/3A) but the board itself doesn't seem starved for power so ¯\_(ツ)_/¯
