I need to add ulab lib in micropython and have executed the following build.sh script. The script is executed successfully and it indicates to run the following command to flash binaries in esp32-c3_usb:

export BUILD_DIR=$(pwd)

echo "--- CLONING ULAB ---"
git clone --depth 1 https://github.com/v923z/micropython-ulab.git ulab

echo "--- CLONING MICROPYTHON ---"
git clone --depth 1 https://github.com/micropython/micropython.git

echo "--- CLONING ESP-IDF ---"
cd $BUILD_DIR/micropython/
git clone --depth 1 -b v4.3.2 --recursive https://github.com/espressif/esp-idf.git

echo "--- INSTALL ESP-IDF ---"
cd $BUILD_DIR/micropython/esp-idf
./install.sh
. ./export.sh

echo "--- MPY-CROSS ---"
cd $BUILD_DIR/micropython/mpy-cross
make

echo "--- ESP32 SUBMODULES ---"
cd $BUILD_DIR/micropython/ports/esp32
make submodules

echo "--- PATCH MAKEFILE ---"
cp $BUILD_DIR/micropython/ports/esp32/Makefile $BUILD_DIR/micropython/ports/esp32/MakefileOld
echo "BOARD = GENERIC_C3_USB" > $BUILD_DIR/micropython/ports/esp32/Makefile
echo "USER_C_MODULES = $(BUILD_DIR)/ulab/code/micropython.cmake" >> $BUILD_DIR/micropython/ports/esp32/Makefile
cat $BUILD_DIR/micropython/ports/esp32/MakefileOld >> $BUILD_DIR/micropython/ports/esp32/Makefile

echo "--- MAKE ---"
make

The command used to flash binaries on ESP32-C3:

esptool.py -p COM3 -b 460800 --before default_reset --after hard_reset --chip esp32c3 write_flash --flash_mode dio --flash_size detect --flash_freq 80m 0x0 bootloader.bin 0x8000 partition-table.bin 0x10000 micropython.bin

Error received:

I tried to change the frequency to 40m in the above command, but no luck. Please help, what is wrong here?
