import wifi crashes on ESP32-S3 DevKitC N8R2, with CP 8.2.0.

[dhalbert]

Please reopen this issue, as I have it on ESP32-S3 DevKitC N8R2, with CP 8.2.0.

I did apply this PR #5858 on CP 8.2.x and it solved my issue!!

@casainho I have created a new issue. And the new problem is that a simple import wifi crashes?

So you're saying the old change from #5858 fixes your new problem? Was the change from #5858 lost? Thanks.

the current content seems to be:

    config ESP_PHY_ENABLE_USB
        bool "Enable USB when phy init"
        depends on USB_OTG_SUPPORTED || IDF_TARGET_ESP32C3

which is different than either side of #5858. It may have been changed by

    Update ESP-IDF to fix PinAlarm
    
    Fixes #5973

it's a bit hard to tell from git history when submodules are involved.

96dd11a seems to have caused ESP_PHY_ENABLE_USB to start being defined when building for BOARD=espressif_esp32c3_devkitm_1_n4

[dhalbert]

The current submodule choice for ESP-IDF is

circuitpython/.gitmodules

Lines 143 to 146 in fad86bf

	[submodule "ports/espressif/esp-idf"]
	path = ports/espressif/esp-idf
	url = https://github.com/adafruit/esp-idf.git
	branch = release/v4.4-circuitpython

, which is different from the older choices above (our fork, new branch)

[dhalbert]

According to https://docs.espressif.com/projects/esp-idf/en/latest/esp32c3/api-reference/kconfig.html#config-esp-phy-enable-usb, it is correct to have CONFIG_ESP_PHY_ENABLE_USB=y for ESP32-C3. When I build the board with the tip of main, that value is set in sdkconfig.

@casainho Getting back to the original problem with ESP32-S3 DevKitC N8R2:

I loaded the 8.2.0 .bin from https://circuitpython.org/board/espressif_esp32s3_devkitc_1_n8r2/

I am unable to cause a crash by a simple import wifi:

Adafruit CircuitPython 8.2.0 on 2023-07-05; ESP32-S3-DevKitC-1-N8R2 with ESP32S3
>>> 
>>> 
>>> import wifi
>>> 

Please describe what you did in more detail, and confirm that you are using the N8R2 S3 board, and that you have the right .bin or .uf2 (and if .uf2, that you have the right UF2 bootloader loaded).

[casainho]

@dhalbert , it resets here (not that my safemode.py is resetting the board):

But with the modified CP as I told:

[casainho]

The code with the issue is here: https://github.com/OpenSourceEBike/EBike_EScooter_modular_DIY/tree/issue_wifi/diy_main_board/firmware

And here the CP binary where the issue do not happen: https://github.com/OpenSourceEBike/EBike_EScooter_modular_DIY/blob/issue_wifi/diy_main_board/firmware/circuitpython_binary/adafruit-circuitpython-espressif_esp32s3_devkitc_1_n8r2-en_US-8.2.x-built_issue_import_wifi.bin

[casainho]

Other interesting thing, is that even with original binary CP 8.2.0, the board appears as N32R8, but is is a N8R2.

[jepler]

I'm sorry for creating confusion by referring to a board with esp32-c3 when this is about a board with an s3 microcontroller (that just happens to have a c in product name too)

[dhalbert]

@casainho I have both the N32R8 board and the N8R2 board. If you look on the tin case of the module in the lower left, there is a stamping that includes either N32R8 or N8R2. Mine identify properly in lsusb. Could you look at the the one that you have and see what it says? Also the N8R2 says ESP32-S3-WROOM-1, and ESP32-S3-WROOM-2 on the N32R8 board.

I am not sure which line is causing the issue from the screen shots. Could you give me a source link to the line in the repo? Click on the line number to get a "...", then click on that and choose "Copy Permalink".

Are you building 8.2.0, or did you try the download version? The submodules have changed a bunch of times, both in terms of URL and branch used.

lsusb says "303a:7003 Espressif ESP32-S3-DevKitC-1-N8R2", so I guess that plugin for Visual Code Studio is showing the wrong data.

But I think the issue seems to be about something that is happening in parallel, and after some time, it resets the board - and not a issue on some specific line of code.

I found this issue when I tried to change the board MAC Address with this code:

import wifi
wifi.radio.enabled = True
my_mac_address = [0x68, 0xb6, 0xb3, 0x01, 0xf7, 0xf2]
wifi.radio.mac_address = bytearray(my_mac_address)

I am using that same code on ESP32-S2, and it works as expected.

Are you building 8.2.0, or did you try the download version? The submodules have changed a bunch of times, both in terms of URL and branch used.

I was using the 8.2.0 from the CP download page. Just now I did built my own version to add the previously mentioned changes.

That photo does not look at all like https://docs.espressif.com/projects/esp-idf/en/latest/esp32s3/hw-reference/esp32s3/user-guide-devkitc-1.html or the photos here: https://www.adafruit.com/product/5310. The buttons are in a completely different place. Could you give a link to the board that you purchased?

[casainho]

This is the board, I bought on Aliexpress:

@casainho Are you using a settings.toml file. If so, what is in it (fine to redact SSID and password)?

@dhalbert My settings.toml is empty, 0 bytes file.

Closing for now as this is old. Please reopen if you have new info.
