ESP32-S3 with 4MB of FLASH cannot run LeafMiner

[PSLLSP]

LeafMiner 0.0.13

Mini module ESP32-S3-Zero, it has chip ESP32-S3, USB-C connector, 18 pins, on-board antenna, RGB LED and two buttons.

LeafMiner flashed with these commands:

esptool.py --baud 115200 write_flash 0x0000 bootloader_esp32-s3.bin

esptool.py --baud 115200 write_flash 0x10000 firmware_esp32-s3.bin

Device doesn't mine and I see in console that flash is corrupted:

It is strange that 4MB of FLASH is not enough to run LeafMiner. NerdMiner_V2 1.6.3 (M5-StampS3) was running at this device for some time...

I think there's something wrong in the flash procedure, but I was lately flashing using Platformio tool and it worked fine for me ( I have two ESP32-S3 running since a few weeks) worth double check

[PSLLSP]

I found different module, it has 16 MB of FLASH. Module has ESP32-S3-WROOM-1 chip, two USB-C ports, 44 pins and RGB LED. I tried to flash NerdMiner but I doesn't work, there is no compatible firmware for this board. It has to be build from the source code...

I flashed it with the same procedure. It cannot mine but it complains with different error:

The error message is in firmware_esp32-s3.bin file. The same applies to error Core dump flash config is corrupted:

$ strings firmware_esp32-s3.bin | grep "PSRAM chip not found"
E (%u) %s: PSRAM ID read error: 0x%08x, PSRAM chip not found or not supported, or wrong PSRAM line mode

I finally find device that can be flashed with LeafMiner for ESP32-S3. LILYGO T-QT. It has 8MB of FLASH and it can run LeafMiner. Display is not used, it is blank. NerdMiner has version for this device, it uses display to show clock and hashrate, just very basic. I think this proofs that the binary firmware of LeafMiner in release cannot be run on device with only 4MB of FLASH...

This is LILYGO T-QT mini display:

But question, still relevant, did you try to build from source using platformio and use it to upload the firmware? I think it can be that the issue is with with flash address at this point

[PSLLSP]

I have not build LeafMiner from source code. I just tried to use binary files downloaded from "Release page". I assumed that I can use these binary files on any board that has compatible chip (ESP32-S3) but that is not the case. And that points to other issue. Documentation of LeafMiner doesn't specify what devices are compatible with release files; what was the development board used to test it, what is reference hardware...
