Can't Flash ESP32-C5 - Chip Revision In Range [v0.0 - V0.99] (this Chip Is Revision V1.0)

by ADMIN 91 views

Introduction

The ESP32-C5 is a popular microcontroller developed by Espressif, known for its high-performance capabilities and low power consumption. However, some users have reported issues flashing the chip, particularly when the chip revision is outside the range of [v0.0 - v0.99]. In this article, we will explore the issue and provide a solution to help users overcome this problem.

Problem Description

The issue arises when trying to flash the ESP32-C5 using the ESP-IDF (Espressif IoT Development Framework) and the esptool.py utility. The error message indicates that the bootloader requires a chip revision in the range of [v0.0 - v0.99], but the actual chip revision is v1.0. This prevents the user from flashing the chip, even when using the latest version of the ESP-IDF.

Possible Causes

There are several possible causes for this issue:

  • Incompatible chip revision: The ESP32-C5 chip revision may not be compatible with the current version of the ESP-IDF.
  • Outdated ESP-IDF version: The user may be using an outdated version of the ESP-IDF, which may not support the latest chip revisions.
  • Incorrect esptool.py configuration: The esptool.py configuration may not be set up correctly, leading to the error.

Steps to Reproduce the Issue

To reproduce the issue, follow these steps:

  1. Connect the ESP32-C5 board to the computer using a USB cable.
  2. Open the terminal or command prompt and navigate to the ESP-IDF directory.
  3. Run the following command to flash the bootloader and firmware:
/home/grigio/.espressif/python_env/idf5.4_py3.9_env/bin/python /home/grigio/esp/v5.4.1/esp-idf/components/esptool_py/esptool/esptool.py -p /dev/ttyUSB0 -b 460800 --before default_reset --after hard_reset --chip esp32c5 write_flash --flash_mode dio --flash_freq 80m --flash_size 2MB 0x2000 bootloader/bootloader.bin 0x10000 blink.bin 0x8000 partition_table/partition-table.bin
  1. Observe the error message indicating that the bootloader requires a chip revision in the range of [v0.0 - v0.99].

Solution

To solve this issue, follow these steps:

  1. Update the ESP-IDF version: Update the ESP-IDF version to the latest release, which may include support for the latest chip revisions.
  2. Use the --force option: Use the --force option when flashing the bootloader and firmware to override the chip revision check.
  3. Check the esptool.py configuration: Check the esptool.py configuration to ensure that it is set up correctly for the ESP32-C5 chip.

Conclusion

The issue of flashing the ESP32-C5 chip revision in range [v0.0 - v0.99] can be resolved by updating the ESP-IDF version, using the --force option, and checking the esptool.py configuration. By following these steps, users can overcome this problem and successfully flash their ESP32-C5 boards.
