How to properly do it? Like many parts of IDF, the documentation is lacking, and the only thing I know is that I have to call `esp_netif_set_ip_info` with the DHCP client not running. Is there no way to kickstart the netif library with this information loaded already, or do I really have to start it...

I'll risk a guess and say it's something related to the OS scheduler plus the fact that `spi_device_queue_trans`, as implied by the name, queues interrupt transactions providing non-blocking transactions, at the expense of time to service the interrupt when the transactions are done. Also, your pre ...

https://docs.espressif.com/projects/esp-idf/en/latest/get-started/linux-setup.html#install-prerequisites 1- Is the different lists of dependencies per distro due to some of them being already pre-installed on that distro or what? 2- What is the bare minimum? By minimum I mean enough to run 'menucon...
Awesome. A couple more questions... https://docs.espressif.com/projects/esp-idf/en/latest/api-reference/peripherals/timer.html#interrupts When handling an interrupt within an interrupt serivce routine (ISR) I don't really get the wording here. Interrupts are handled inside ISRs, right? Since that's ...
Oh well, I just posted another closely related question on the forums and I can't find it due to it being submitted to approval, because I thought this one had not been posted and I didn't see any notification until after I did it. I would like the discussion to continue on the other thread, as I go...
1. What is the point of a prescaler anyway? From what I understand, it scales down the clock count, which basically reduces the resolution of the counter. 2. Why would that be good or intended? There must be a very good reason why hardware makers would put that in a CPU, and why is that? Moving on t...
https://docs.espressif.com/projects/esp-idf/en/latest/api-reference/peripherals/timer.html#introduction The ESP32 chip contains two hardware timer groups. Each group has two general-purpose hardware timers. They are all 64-bit generic timers based on 16-bit prescalers and 64-bit up / down counters ...

What exactly performs this action? And when is it performed?If newer firmware (v3.2) sees the NVS partition produced by older firmware, it will automatically update the format of the partition.
Is it one of the python scripts at building time, or automatically at boot time? Or what?
