After doing some more resting, I found one of my pointers wasn't allocated correctly. Now the writes to the partition and reading through accessing the variable work great so looks like I'm all set!

Ok, so I've gotten basics of initializing and writing the flash paritition based on the paritition_mmap example (https://github.com/espressif/esp-idf/tree/master/examples/storage/partition_api/partition_mmap). On the readback, if I generate a void* pointer from esp_partition_mmap and cast it to a st...

Awesome, I'll give that a shot. That will at least give us a few MB of space to work with and test out. Thanks!

Thanks ESP_Sprite, I appreciate it. Yeah, that was what I expected. We're considering some of the -S3 variants with the onboard PSRAM (ours is the MINI :-/)

On the internal flash, we do have a good chunk of our 8MB free. How would we go about memory mapping that?

Cheers,
Matt

Hi all, I'd like to process some large chunks of data on the ESP32-S3, but of course running malloc() on several MB of data is well past the limit of the onboard RAM. We do have an SD card connected, so is there a way to map the SD card such that we could use it for memory space? I understand with t...

Thanks ESP_Sprite, I found that to be true when I fully erased the devkit and the boot loop occured there as well. It's a bummer that's an issue, but I think we can live with that. As for the auto programming portion, I found that esptool wasn't auto detecting my chip, so it was setting default_rese...

Hi all, I'm using the ESP32-C3-MINI-1-N4 on a custom PCBA. Before designing the board, I used the ESP32-C3-DevKitM-1 devkit to prove out USB serial programming. From what I read, it's possible to program via USB using either 1) a USB-to-serial converter chip (FTDI) or 2) directly connecting to USB. ...
