Thanks for asking, ESP_Sprite. Yes, C7 & C8 are not populated.

lbernstone, many thanks for your suggestions.

I tried using your tool settings: the board programmed and I began seeing the expected serial output!

I then increased the Flash Size to 8MB and the partition scheme to "Minimal SPIFFS (1.9MB APP with OTA/190KB SPIFFS)" (I believe I'm using ESP32-S3 ...

Using Arduino 1.8.16, I'm trying to program this ESP32S3-Mini-1:

My tools setup is:

***NOTE: I've also tried this with Flash mode set to QIO 80MHz & QIO 120 MHz
I've simplified my setup code to simply:
void setup(void) {
pinMode ...

Back after a long break...



You can read those partitions using esp_partition_* API calls.

When the ESP boots, it tends to use a CRC or hash to figure out if the current OTA partition is corrupted; it'll try to boot the other OTA partition (if valid) and then the factory partition if that ...

Thank you, mbratch, I appreciate the helpful affirmation!

I want to add Matter functionality to my next-generation hardware. But I can't find any description of the minimum requirements for program and data memory for any of the modules. Does this exist yet, and if so, where can I find it?

Thanks a heap!

Thank you for your responses mbratch and ESP_Sprite. mbratch, you suppose correctly about my intended operation.

Based on my limited research, it seems that the charge in Flash cells gradually dissipates, and eventually errors are likely, if not certain. I would like to assure the proper operation ...

Is the ESP32 able to read its program memory for comparison to OTA memory? I want to make a memory scrubber to maintain program integrity for the longest possible time.
Thanks!
