Firmware for ESP32-C3 - Githubissues

robostart-io commented 2 years ago

Good day, dear Michael and creators of microlite! Thanks for your wonderful project. This is a very handy item. It seems to me that his appearance is a very big event in the world of micropython. Let me ask you, is it possible to create a firmware for the increasingly popular ESP32-C3 based on RISC-V?

mocleiri commented 2 years ago

At the moment I'm not building for all boards only the ones that people ask for and can verify. If you have an ESP32-C3 to test with I can add a build for it.

Normally I copy the board configs from micropython and then customize as needed for the microlite module. Which board config are you using?

robostart-io commented 2 years ago

We use the ESP-C3-M1 KIT 4M board to study microcontrollers and create educational projects.

ESP-C3-M1 KIT has a small width and length and can be installed on any solderless breadboard, even the SYB-170 mini. It has an RGB LED, which is convenient to use as a multi-color indicator without resorting to additional elements. At the same time, it is very cheap and quite powerful.

We are programming in MicroPython using a programming environment I made for learners and beginners. Now I'm making a variant for Linux. You might also like this IDE.

https://github.com/micropython/micropython/discussions/9333

I would be very grateful if you could build a microlite for this board. My students also join my gratitude.

I've started work on this but the build isn't quite working yet. You may also want to take a look at https://github.com/espressif/tflite-micro-esp-examples

Which is Espressif's tflm repository, the only downside is you have to compile using C/C++ instead of using micropython.

The C3 is only a single core so you may need the acceleration library integrated there to get acceptable speed.

Its a work in progress to get the esp_nn library merged into this repo. I tried a few months ago but it locked up my normal esp32's when trying to run inference and I haven't been back around to try again.

robostart-io commented 1 year ago

Thank you so much for getting started! Unfortunately, working with ESP-IDF is problematic for many reasons for beginners. So far, we are using your build for a regular ESP32 under MicroPython and are very happy with it. We are ready to wait as long as necessary, and will make every effort to test and debug it. Thank you very much again.

I thought how I could be useful to your project? Decided to make a logo for it. Logo for Tensorflow Micropython Examples

Hmmm, Link does not work for me.

robostart-io commented 1 year ago

Sorry, added access

mocleiri commented 1 year ago

@robostart-io my latest change built the firmware successfully. Can you download the applicable zip from here: https://github.com/mocleiri/tensorflow-micropython-examples/actions/runs/3662193220

You have to unzip the file and then flash using the different parts. This comment shows how the bits in the zip file can be combined into a flashable .bin file:

https://github.com/mocleiri/tensorflow-micropython-examples/issues/99#issuecomment-1272576632

There are a couple of more changes needed for the other ports before this work will merge down into the main branch. But you should be able to confirm if the build is producing working firmware or not.

After turning off the power and turning it back on, the COM port does not respond and does not output anything.

mocleiri commented 1 year ago

Can you try flashing at a slower baud rate? Sometimes that can help.

I found this esp-idf issue that had the same error message which might help: https://github.com/espressif/esp-idf/issues/9005

Changed the cable. Changed the board with ESP32c3. Сhanged computer. Changed the terminal program. The result is the same.

Yesterday I wrote: "After turning off the power and turning it back on, the COM port does not respond and does not output anything". This is not entirely true. After turning off the power and turning it on again, the port in some cases receives a constantly recurring invalid header: 0xffffffff.

How else could I test to help make the build?

robostart-io commented 1 year ago

I used two types of boards for testing

ESP-C3-M1-Kit

ESP-C3-32S(4M)-KIT

robostart-io commented 1 year ago

I tried with old versions of esptool, but I get it again invalid header: 0xffffffff.

mocleiri commented 1 year ago

What board config do you use from micropython? For the microlite C3 images I am building directly from the micropython GENERIC_C3 and GENERIC_C3_USB configurations.

To troubleshoot I just made a new image for the esp32s2 as I do have this board https://docs.espressif.com/projects/esp-idf/en/latest/esp32s2/hw-reference/esp32s2/user-guide-devkitm-1-v1.html

Mine got stuck at the power on step until I removed the usb configuration as this dev board has the serial chip. Have you been flashing the generic_c3 image?

robostart-io commented 1 year ago

For C3 I used a GENERIC_C3. I'm flashing the microlite-esp32c3-firmware.

On the page https://micropython.org/download/esp32c3/ with the firmware for esp32c3 it says

From then on program the firmware starting at address 0x0

Maybe that's the problem?

mocleiri commented 1 year ago

Good catch, Can you try with the firmware starting at 0x0?

I built the MICROLITE_C3 images directly using the upstream board config so any guidance on the placement should be the same.

It looks like its an esp32c3 particularity as some of the other c3 boards also say to flash from 0x0 instead of 0x1000 which is used for the xtensa based boards.

robostart-io commented 1 year ago

If I write 0x0,

python esptool.py -p COM6 -b 115200 --before default_reset --after hard_reset --chip esp32c3 write_flash --flash_mode dio --flash_size detect --flash_freq 40m 0x1000 bootloader/bootloader.bin 0x8000 partition_table/partition-table.bin 0x0 micropython.bin

then there is an overlap:

esptool write_flash: error: argument <address> <filename>: Detected overlap at address: 0x1000 for file: bootloader/bootloader.bin

Maybe need to do something with the partition-table?

robostart-io commented 1 year ago

I tried to flash with the key -z

python esptool.py -p COM6 -b 115200 --before default_reset --after hard_reset --chip esp32c3 write_flash -z --flash_mode dio --flash_size detect --flash_freq 40m 0x1000 bootloader/bootloader.bin 0x8000 partition_table/partition-table.bin 0x10000 micropython.bin

mocleiri commented 1 year ago

@robostart-io can you retry using the firmware available on the latest main branch: https://github.com/mocleiri/tensorflow-micropython-examples/actions/runs/3727394123

I integrated @uraich's script which builds a unified firmware binary that should be directly flashable using the micropython instructions.

Now there will be a single firmware.bin file in the zip file that can be flashed.

I tested flashing the standard esp32 microlite firmware and it worked so I think the c3 version should also work.

esptool.py --chip esp32c3 --port COM6 --baud 460800 write_flash -z 0x0 firmware.bin

I bought an esp32c3 board to further investigate this issue. https://www.seeedstudio.com/Seeed-XIAO-ESP32C3-p-5431.html

I was able to successfully flash micropython 1.19.1 but get the same load access fault error when booting on microlite.

I need to look at the espressif tflite-micro repo to see if they are doing anything special for esp32c3. On the tensorflow side the generator isn't doing anything xtensa specific.

There is a way to decode the fault or I might need to solder the JTAG pins to debug in visual studio to try and understand where the error is coming from.
