Have you had a look at the documentation? https://docs.espressif.com/projects/esp ... -v-program

Espressif chips are not "hardened" to the extent that you could use them, e.g. in a bank, medical or defense environment (to my knowledge anyway). As a consequence, a dedicated adversary would likely always be able to extract your firmware, possibly by means of an electron microscope, laser attacks ...

However, because I have no CS line, it seems that the : err = spi_slave_transmit(SPI2_HOST, &Transaction, portMAX_DELAY); never exits. That api seems to expect transactions delineated by C's changes. Two options that come to mind: - toggle the CS state on a fake pin by setting their pull-up and pul...

So you mean that it is not possible to use the RISC-V ULP Copro as an extra code and do processing while the other cores are running ? Even in normal mode ? No I mean the ULP is not a third core for additional processing power or more IO peripherals. It's a minimal subsystem intended to allow selec...

So my question is the following, is it possible to flash the Esp32-S3 (With ESP-IDF) using the UART pins directly ? (Without the USB connector and the UART/USB transceiver) ? Yes, all the usb/uart transceiver does is allow your PC to "speak" uart. If you can access the serial pins directly, there i...

My understanding is that the ULP does not support the SPI peripheral, at least not via an API. I doubt that it would be able to access the SPI peripherals via memory mapped IO, but even if it could, you said all the SPI's are already in use. This would mean that you would need to bitbang SPI. If you...

Quick additional question: is the an idf.py command I'm missing to compile the component to a static archive? Or does that always have to occur in the context of compiling a project. (Sorry if this is obvious to people who put in the effort to understand the cmake process, I realize I'm being lazy

We're currently organizing some of the boilerplate code we use frequently into idf components to facilitate reuse. Functionality such as network setup boilerplate, sensor drivers, basic infrastructure for ota device configuration, etc. The component template generated by `idf.py create_component` se...

Some hosts don't respond to pings. Some network configurations may filter the necessary ICMP packets.

- Can you ping the target from a laptop connected to the same Wifi?
- Can you ping a different target from your device?
- Can you open a network connection (e.g. HTTP) from your device?

Just a guess: what is the antenna situation? It seems like maybe your device expects a ufl antenna, but nothing is attached and the reception on the windows side is bad. Apart from that, try to use a sample firmware and see if that works to eliminate the possibility that the cause of the problem is ...
