Re: Flash write/read issue
Could it be that your code is running without you seeing it? Could be that between flashing and opening the monitor (which resets the processor), the CPU gets to execute code for a little bit.

Re: Espressif and product upgrade path
Well that's an MCU without any connectivity, and is even less suited than what's out there already. Note that the intent of the P4 is for it to easily and transparently pair up with one of our C-series chips (e.g. the C3 or C6 or in the future the C5) allowing it to connect to things in the same wa...

Re: ESP32-C3-DevKitC-02 SPI issue
I would just have a question before closing the topic, How can I configure this SPI communication to use DMA? What would be the maximum size of data I could send? You already have the answer to both questions in your code: you use SPI_DMA_CH_AUTO and set .max_transfer_sz to whatever the maximum is ...

Re: Generate signal with timer
Do you have an issue specific with the LEDC? If so, you can also use the MCPWM or the RMT, or even hack stuff up using e.g. I2s, to generate such a signal. If you specifically want to generate a signal using a software interrupt, it would really help if you would tell us why exactly. (And the answer...

Re: FreeRTOS Task causes TWDT triggered
Hm, no clue. Any other tasks doing anything with lvgl? Wondering if you may have some sort of concurrency issue.

Re: Download from S3 bucket
While the buffer's argument is char in esp_http_client_read(esp_http_client_handle_t client, char *buffer, int len), the content_length is assigned to the buffer with that size since esp_http_client_get_content_length(client); returns int. based on the content_length while allocating the buffer You...

Re: ESP32-C3-DevKitC-02 SPI issue
FWIW, I see nothing wrong with your code... I assume running it does not spit out any errors? Perhaps you're measuring the wrong pins or something?

Re: Is the 8266 processor supported ?
I'd like to be ahead of the troops, but it seems there is no suitable RISC-V version for me yet. The "mini" boards that I like (2.54 mm pitch pins but still very small) are all with S2 orc S3. So I guess that will be for a future project. I don't think the P4 will be very cheap (as an end-user-prod...

Re: Protect counter variable by portENTER_CRITICAL vs <atomic>
Atomics are supported, and as long as you use a 32-bit atomic, access is a lot faster as the hardware will take care of atomicity rather than needing code for critical sections.
