Hi @dlakatos847,

did you managed to find solution to your problem?
I have exact same problem - using espflash rust program, which works, using esptool results in illegal instruction

I have non-C bare metal application which I want to run from flash of the ESP32-C3. I don't want to use bootloader nor partitions.

Flashing that application to the MCU works with unofficial tools. I am interested in doing that with official esptool (take .elf, do "something with it" and flash it to ...

Is it possible to use esptool.py for flashing non-IDF bare metal (without bootloader and partition) binaries?
I tried:

esptool --chip esp32c3 erase-flash
esptool --chip esp32c3 elf2image --flash-mode dio --flash-freq 80m --flash-size 2MB --min-rev 3 --min-rev-full 3 --max-rev-full 199 -o fw.bin fw ...

Is it possible to have 3 USBs at the same time on ESP32-P4?
GPIO24,25 - USB JTAG and UART (hard coded)
GPIO25,26 - USB device (eg keyboard or storage)
DP, DM - USB host or device

The best I got is 24,25 as JTAG and DP,DM as device (eg, IDF/examples/peripherals/usb/device/tusb_msc).

Hi,

Could you try to use ESP-IDF without Arduino and see if it works there?
If not, paste error message here (as text, not as a screenshot)

Try it without SD card, and it will work. Or specify SDIO1 (slot 0) because examples use same SDIO2 for both SD card and SDIO WIFI.

I had same worries trying to fix my SD card, but LDO is okay, I still have that error and my SDIO WIFI (and SD card) works:

There is also this https://en.wireless-tag.com/product-item-56.html
But I don't see schematic of the module

You could power it without flash attached, put it in download mode, and burn fuse

My board was working okay. Tested HW things: UART, GPIO, SPI LCD, I2C, ...
And how I can add SD card on that list! :mrgreen:
It is HW fault. Again...
LDO VO4 was indeed 3.3V, but there is transistor between that voltage and VCC SD. VCC SD was at 1.1V regardless is transistor's gate set to low or ...
