Re: DNS not resolvable if hosting provider is using QUIC

You don't really want raw packet debugging did you turn on LWIP_DNS_DEBUG

Re: DNS not resolvable if hosting provider is using QUIC

I doubt this has anything to do with QUIC. You should check the response using a command line dns lookup not a browser. And turn on lwip debugging to see why the error happens on esp32.

Re: Why would streaming UART traffic break wifi?

Using a while loop to empty the fifo is not a problem, the idf driver does the same thing. The fact that your interrupt runs every 2 bytes is not great though since bit times get smaller with higher baud rates.

Re: flash encryption not happening at first boot

Nothing wrong with those efuses. Encryption and secure boot are enabled. What does bootloader log say? Are you sure those plaintext aren't leftover from a previous flash because you didn't do a full flash erase?

Re: Factory app partition write protection

It is possible to write protect flash chip regions using the chip's hardware features if you set flash chip status register. Or you could get some protection by modifying esp_partition_main_flash_region_safe function.

Re: More than 320Kb of Sram possible?

esp32 chips have 520kb sram but only 328kb is on the data bus and some memory is reserved for certain purposes. You didn't say how you are expecting to be able to use the memory in your app. If you need more ram the best option is to buy a board with external psram.

Re: Extra memory after "run FreeRTOS only on first core"

It does default to the pro cpu. If you are not running freertos on the app cpu then you are not using the app cpu.
