Re: Is the flash size specified in MB or MiB?

Flash in general doesn't pull hard drive shenanigans, so a MB indicated there is 1024*1024 bytes.

Re: Phase matching timer interrupt sequence with LEDC PWM

The clock source is the same (usually the ABP clock of 80MHz) and as such if you start two timers with the same cycle time, they should be clocked at exactly the same frequency, but they are still two separate timers so any phase difference (=difference in time between starting the two) will be kept...

Re: Simple Semaphore as task delay with interrupt

That should work (given you uncomment the two lines in loop()). Two things of note:
- vTimerISR is unused in your code, and
- xSemaphoreGiveFromISR will work but is more useful for use in interrupt handlers. If you're not in an interrupt handler (ISR) you can use xSemaphoreGive instead.

Re: Accessing the Flash on SPI0 of esp32 -wroom-32

That depends on the partition layout you selected.

Re: How to program my ESP32 using WSL2?

You could possibly get away with this, but the reset and jump to bootloader are normally done with handshaking lines which won't be forwarded by socat. If you manually pull GPIO0 low, reset the ESP32 and try to upload, it might work.

Re: Partition table without factory partition

If there is no factory app, the bootloader will normally just always boot from the active OTA app.

Re: Debugging DevKitv3 with Visual GDB

Looks good to me. Sorry, I'm stumped then :/ You could try to use a 'scope to perhaps trace the JTAG lines, see if there's any obvious going on there.

Re: ESPNOW working on a router / Acces Point?

Not easily, as the access points WiFi stack should somehow allow you to send management frames. On top of that, you'd have to write something that sends out the specific management frames ESPNow expects.

Re: ESP_OTA: OTA image has invalid magic byte

Hard to say... are you sure your webserver doesn't use e.g. Javascript to redirect to the actual download? A webbrowser would follow that, Curl and the ESP32 would not. Grab the file using Curl and open it in a text editor, that should tell you enough. Given that cloud providers aren't really made f...
