While this works for the old ESP32:

Boot bin file - 0x1000
Partition bin file - 0x8000
App bin file - 0x10000

The S3 boot file needs to be:

Boot bin file - 0x0

These are not using encryption

Thanks a milion, worked like a treat.

Strange dev choice (to me) to make it per project rather than global, but hey, it works.

Noted. Thanks for your help. I'll use the low frequency for now and mess around with the higher frequencies when I get around to production quality video lighting tests. Might need a different MCU or go analogue.

Thanks, that make perfect sense. Does that mean I would have to remove vTaskDelay and block the core for that single task or probably better still, use an ISR timer with call back to run LEDC for higher frequencies?

That is entirely probable, I am a beginner. This is the code in case it is something obvious. Still wouldn't mind knowing the other information if anyone knows.

#include <stdio.h>
#include <math.h>
#include "freertos/FreeRTOS.h"
#include "freertos/task.h"
#include "freertos/queue.h"

I have some code using LEDC_TIMER_10_BIT with a frequency of 1kHz that runs but causes watchdog errors. The errors continue if I drop the freq to 500Hz so I tried 50Hz which worked. My understanding is that LEDC_TIMER_10_BIT should support up to about 78kHz, but I also understand that some of the ...

I have tried to find an answer both here and for the Eclipse IDE but I have not found the answer so far. I have turned nearly everything off in the Window > Preferences section and still get the description added to the code snippet below.

The italics is auto-filled and cannot be edited or even ...

So no luck. I have looked at the datasheet for both the 32D and the S3 as well as the S3 technical reference manual and cannot find anything about the memory locations. I also checked the esptool online guide and the local man pages.

After bouncing around the website trying to find these memory ...

So after some more research I was right on both counts. I did not understand both how the firmware is flashed and how to use the esptool command. I need to flash the bootload.bin, partition-table.bin and my-app.bin. I saw an example where 0x0, 0x8000 and 0x10000 as the memory locations. I am having ...

I am moving from the Arduino IDE to Eclipse with ESP-IDF due to limitations and am having some boot issues. The device boots fine with Arudino code but not sample code from Eclipse.
I Installed Eclipse and ESP-IDF, then opened a new workspace and project. I was prompted to import ESP-IDF which I ...
