Esp32-S3 Firmware uploading Problem

[sheetaljain01]

Hi,

I have created custom firmware for the ESP32-S3 and obtained the following files: micropython.bin, bootloader.bin, and partition-table.bin.

While uploading the firmware using the following command:

python3 -m esptool --chip esp32s3 --port COM5 write_flash 0x1000 bootloader.bin 0x8000 partition-table.bin 0x10000 micropython.bin

my ESP32-S3 keeps rebooting and shows this error continuously:

ESP-ROM:esp32s3-20210327
Build: Mar 27 2021
rst:0x10 (RTCWDT_RTC_RST), boot:0x8 (SPI_FAST_FLASH_BOOT)
SPIWP:0xee

load: 0x20736177, len: 0x6c6c6163
Invalid image block, can't boot.
ets_main.c 329

This error keeps repeating. Can you help me troubleshoot the issue?"

You should have a firmware.bin after a build process. Then you can try:

python3 -m esptool --port COM5 --baud 460800 --before default_reset --after hard_reset --chip esp32s3  write_flash --flash_mode dio --flash_size detect --flash_freq 80m 0x0 firmware.bin

Thanks for your reply. I am compiling MicroPython with ADF support for the KORVO2V3 board. However, while building, I didn’t get the firmware.bin file in the build folder.

I am following this repository: https://github.com/espressif/esp-adf/tree/master/micropython_adf.

Could you help me resolve this issue?

Then please try:

python3 esptool --port COM5 --baud 460800 --before default_reset --after no_reset --chip esp32s3  write_flash --flash_mode dio --flash_size detect --flash_freq 80m 0x0 bootloader.bin 0x8000 partition-table.bin 0x10000 micropython.bin

The offset of the firmware is 0x0 and not 0x1000.

µController	Offset
ESP32	0x1000
ESP32S2	0x1000
ESP32S3	0x0
ESP32C3	0x0
ESP32C6	0x0
