Hi, I'm about to buy a JTAG debugger. The ESP32 docs says that Espressif have used the Flyswatter2 and TIAO-devices, but would any JTAG device supported by OpenOCD-esp32 work, i.e. any device listed on the page https://github.com/espressif/openocd-esp32 ? Can anyone recommend a good debugger, beside...

Thanks

Anyone? I'd really appreciate some feedback on these two questions.

Perhaps its just me, but solely relying on OTA is like asking for trouble imho. I'd definitely add a place for a pin header in the design, just to be sure that it is possible to restore a bricked item. You don't even have to fit it in production, but it is there when/if you need it. Just my 2 cents.

Hi, Based on the array GPIO_PIN_MUX_REG in this source file , it seems any GPIO, including the input-only pins, can be used as an interrupt source, which is great. It also seems that any interrupt can be set either level or edge triggered using gpio_set_intr_type . However, section 2.3.2 of the Tech...

Ok thanks, now I can stop trying to make sense of the names, and just accept them as-is.

That only states that they're # 2 and #3, not the meaning of H and V, which is what my question is about.

Hi,

HSPI and VSPI are referenced throughout the documents and this forum, but I've seen no explanation as to what the H and V actually stands for - could someone please enlighten me?

Ok, at least I'm thinking about it correctly.

Ok, so that means that I can't have both JTAG and Ethernet running at the same time since they both use the MTMS-pin (17), right? By pulling MTDO/GPIO15 low, you can disable the debug logging on U0TXD, but if doing that by grounding it, you also prevent MTDO to be used by anything else unless you ha...
