Waveshare S3 touch 3.5 - mpremote cp crashed

[quantrpeter]

Hi
I used these commands to build the image and burn to waveshare s3 touch 3.5 device, i can use mpremote to enter the shell. If i copy a 277kb image to device, it crashed at 14%

ok, do you have enough flash storage?

If you look near the end of the build output it should tell you what the partition sizes are. lets make sure there is enough space,

[quantrpeter]

hi @kdschlosser the "mpremote df" show i have 14.1MB free space. The spec said the device has 16MB flash.

I have set 16MB "--flash-size=16" during the python3 make.py and i saw

To flash firmware:
Replace `(PORT)` with the serial port for your esp32 and run the following command.

/home/peter/.espressif/python_env/idf5.4_py3.13_env/bin/python -m esptool --chip esp32s3 -p (PORT) -b 460800 --before default_reset --after hard_reset write_flash --flash_mode dio --flash_size 16MB --flash_freq 80m --erase-all 0x0 /home/peter/workspace/lvgl_micropython/build/lvgl_micropy_ESP32_GENERIC_S3-16.bin

[kdschlosser]

the flash size is not detected it is something that you set. If you have set the size wrong MicroPython is going to report it wrong. what is the ESP32 model you are using?

[lanmark7]

I am getting issues creating a build that actually works as it disconnects any time a file is transferred to the device and only part of the file is transferred. One thing I noticed is when I run the make.py and look at the output like yours above I see that ESP-IDF 5.4 is being used, however looking at micropython's documentation it states that only up to 5.2.2 is supported... so I am wondering if that could be the issue.

Is there a way to specify the ESP-IDF version? I tried removing the esp-idf folder and cloning the 5.2.2 but when I run a make it looks like it is back to 5.4.

[kdschlosser]

you cannot specify a version...

I do know that there have been issues with mpremote and the ESP32 MCU's especially if they are using USB CDC instead if a UART. The S3 defaults to using USB CDC and that could be what your issue is.

Optionally you can use a library like ampy to transfer files to the ESP32. I know that ampy can be glitchy sometimes when running it sometimes requiring it to be run more than once to get it to connect but it does get the files uploaded without issue.

I believe that the latest release of MicroPython has fixed the issues with mpremote and I was waiting a few weeks to make sure that nothing severe showed up in the latest release in terms of bugs. I will take a look and see if there is any new issues with the latest release and if there isn't anything major and issues have been sorted from the release before it I will update the micropython version being used within the next few days.

Cool?

[lanmark7]

I am not sure it is USB CDC as wouldn't using the build flags be a resolution?

--enable-cdc-repl=n
--enable-jtag-repl=y
--enable-uart-repl=y

When transferring files to the device it seems to stop exactly at 1kb (1024 bytes). No matter what file I transfer it stops right at 1024 bytes. I have tried every combination of the above flags and it does not seem to change the result as well as trying it on Pycharm and Thonny. I haven't yet used ampy to rule that out.

[kdschlosser]

--enable-jtag-repl=y is similiar to USB-CDC.

How many USB ports are there on the board you are using?

[kdschlosser]

don't use thonny or PyCharm. use the command line.

[lanmark7]

--enable-jtag-repl=y is similiar to USB-CDC.

How many USB ports are there on the board you are using?

Single USB on both boards I am trying.

This variety of board:

[kdschlosser]

ok you should be using USB CDC and not the UART or JTAG.

--enable-cdc-repl=y --enable-jtag-repl=n --enable-uart-repl=n

and you will also want to add --flash-size=16 to your build command as well. The MCU you are using doesn't have any FLASH that comes with the MCU. It is an addon that WaveShare put in. So I am not going to be able to tell you how the compatibility is or the quality of the SPI connection to the MCU.

The display IC is JD9853 and the touch IC is AXS5106L. There are drivers written for both of those and you need to add those drivers to your build by adding DISPLAY=jd9853 and INDEV=axs5106 to your build command as well.

[lanmark7]

I bought a C6 version (https://www.waveshare.com/esp32-c6-touch-lcd-1.47.htm) of the same board with the JD9853 driver.. did a build using just the following:

python3 make.py esp32 clean --flash-size=8 BOARD=ESP32_GENERIC_C6 DISPLAY=JD9853

Flashed the board and do not experience any of the same issues the two ESP32S3 are experiencing. I am able to copy the same files as before to the device. Do you have any ideas on why the S3 version would be having the issues.?

[kdschlosser]

it's because the C6 doesn't have pins to connect a UART to it only has JTAG or CDC.

I have also not checked to see if the flash chip for the MCU you are using is internal to the ESP32 or if it's external. I suspect that it is internal so it is going to be tested thoroughly by Espressif to ensure it's compatibility and that it is functioning properly prior to shipping. The S3 variant of your board uses and ESP32 that doesn't have any internal FLASH storage, it is all external and that could be what is causing the issue. You could have a faulty FLASH memory chip or a setting might need to be adjusted to get it to work properly. That's the only thing I can come up with.

There are a heap load of settings for using external flash chips and you would need to do the research to find out what needs to be done for that specific chip that is being used and set the CONFIG_* settings correctly. Those settings are able to be passed to the build system using the build command. or you can optionally make a custom board definition to set the settings

I am ok on C6 too, just S3 not working

[lanmark7]

ok you should be using USB CDC and not the UART or JTAG.

--enable-cdc-repl=y --enable-jtag-repl=n --enable-uart-repl=n

The display IC is JD9853 and the touch IC is AXS5106L. There are drivers written for both of those and you need to add those drivers to your build by adding DISPLAY=jd9853 and INDEV=axs5106 to your build command as well.

Using these build parameters does not work. When plugging in the device the boot.py doesn't even show up and transferring anything to the device causes a crash / reboot / disconnect.

[quantrpeter]

added "--enable-jtag-repl=y" but got these:
