Thank you for the reply,
Now it makes sense to me on what is happening under the hood.
So the only method of converting char* to a base address is by mapping?
I'll study the macro's a bit more, the documentation about them was quite sparse.

Event Loop Base issues
Hi, I've been trying to implement the Event Loop Library. Posting and registering events using a hardcoded static string works fine. When the string is dynamic and identical to the base it fails to trigger. I'm registering an event using: esp_event_handler_instance_register("COMMANDBASE1", 0, comman...

How to invoke RUN_USER_CODE from stub loader? (esptool)
My board has a ESP32-S3 that I want to reset after uploading. Based on the the documentation a stub loaders is send to supplement the bootloader found in ROM. This stub has the option to run user code (effectively a soft-reset). My platformio .ini files looks like this: [env] platform = espressif32 ...

Re: ESP32-S2 outputs in parallel to increase max current.
And If the load was purely resistive load instead? Would sharing the current break a single pin?

ESP32-S2 outputs in parallel to increase max current.
40mA is the maximum current sourced by a single pin as specified in the datasheet. I have a relay (FH42L-LCSC) that requires 83.3mA (±10%) for about 15ms.
Can I put 5 output pins in parallel to share the load or would one pin fail/break?

Re: Initial flash needed for download boot over internal USB?
So this would work?
Flashing a binary file with IDF on a new/fresh/empty ESP32-S2 over the internal USB (USB-OTG) peripheral.

Initial flash needed for download boot over internal USB?
I want to design a minimal PCB around the ESP32-S2-MINI with just: Crystal circuit Boot/Reset button USB connector directly on D+ and D- Voltage regulator Can I use IDF to download a fresh/new/empty ESP32-S2-MINI with just the internal USB? OR do I need JTAG/UART for the initial flashing?
