TTGO T8 V1.7 ESP32 board lacks PSRAM management

[robertoseno]

Circuitpython releases 9.1.4 and 9.2.0 manage apparently correctly the 4MB Flash but both lack PSRAM management.
You can find in circuitpython-main/ports/espressif/boards/ttgo_t8_v1_7/mpconfigboard.mk that there is no PSRAM declaration:

CIRCUITPY_CREATOR_ID = 0x000C303A
CIRCUITPY_CREATION_ID = 0x00320005

IDF_TARGET = esp32

CIRCUITPY_ESP_FLASH_MODE = qio
CIRCUITPY_ESP_FLASH_FREQ = 80m
CIRCUITPY_ESP_FLASH_SIZE = 4MB

CIRCUITPY_ESPCAMERA = 0

Looking at Adafruit FeatherS2 for example you can see:
USB_VID = 0x239A
USB_PID = 0x80EC
USB_PRODUCT = "Adafruit Feather ESP32S2"
USB_MANUFACTURER = "Adafruit"

IDF_TARGET = esp32s2

CIRCUITPY_ESP_FLASH_MODE = qio
CIRCUITPY_ESP_FLASH_FREQ = 80m
CIRCUITPY_ESP_FLASH_SIZE = 4MB

CIRCUITPY_ESP_PSRAM_SIZE = 2MB
CIRCUITPY_ESP_PSRAM_MODE = qio
CIRCUITPY_ESP_PSRAM_FREQ = 80m

Please can you add PSRAM management for TTGO T8 V1.7 ESP32 board too?
Thanks

Do you feel like you could submit a PR? Most of us don't have this board available to test.

I added support for this board, but I am not sure how to add support for that. Any idea?
Edit 1: On another note, are you sure you mentioned the right file? It actually looks like this: https://github.com/adafruit/circuitpython/blob/main/ports/espressif/boards/ttgo_t8_v1_7/mpconfigboard.mk

CIRCUITPY_CREATOR_ID =  0x000C303A
CIRCUITPY_CREATION_ID = 0x00320005

IDF_TARGET = esp32

CIRCUITPY_ESP_FLASH_MODE = qio
CIRCUITPY_ESP_FLASH_FREQ = 80m
CIRCUITPY_ESP_FLASH_SIZE = 4MB

CIRCUITPY_ESPCAMERA = 0

Edit 2: It looks like the config you posted is meant to be the fixed mk file? Anyway it has some references to Adafruit Feather ESP32S2, if you could fix that and add send a PR (As I originally did :P) it would help a lot.

I tried adding the following 3 lines:

CIRCUITPY_CREATOR_ID =  0x000C303A
CIRCUITPY_CREATION_ID = 0x00320005

IDF_TARGET = esp32

CIRCUITPY_ESP_FLASH_MODE = qio
CIRCUITPY_ESP_FLASH_FREQ = 80m
CIRCUITPY_ESP_FLASH_SIZE = 4MB

CIRCUITPY_ESP_PSRAM_SIZE = 4MB   <--------------------------
CIRCUITPY_ESP_PSRAM_MODE = qio   <--------------------------
CIRCUITPY_ESP_PSRAM_FREQ = 80m   <--------------------------

CIRCUITPY_ESPCAMERA = 0

but I get the following warnings:

Any idea why?

Hi,I am sorry but I stopped trying for similar reasons.I don’t know internal structure of micropython  tool chain use to build the final file and don’t know where to look at for further critical points.Without adafruit support no hope to solve the problem, at least from my point of view.Best regards and good luckIl giorno 23 nov 2024, alle ore 01:15, aguaviva ***@***.***> ha scritto: I tried adding the following 3 lines: CIRCUITPY_CREATOR_ID = 0x000C303A CIRCUITPY_CREATION_ID = 0x00320005 IDF_TARGET = esp32 CIRCUITPY_ESP_FLASH_MODE = qio CIRCUITPY_ESP_FLASH_FREQ = 80m CIRCUITPY_ESP_FLASH_SIZE = 4MB CIRCUITPY_ESP_PSRAM_SIZE = 4MB <-------------------------- CIRCUITPY_ESP_PSRAM_MODE = qio <-------------------------- CIRCUITPY_ESP_PSRAM_FREQ = 80m <-------------------------- CIRCUITPY_ESPCAMERA = 0 but I get the following warnings: -- Project sdkconfig file /home/raul/repos/circuitpython/circuitpython/ports/espressif/build-ttgo_t8_v1_7/esp-idf/sdkconfig Loading defaults file /home/raul/repos/circuitpython/circuitpython/ports/espressif/esp-idf-config/sdkconfig-ble.defaults...

Did you do make clean BOARD=ttgo_t8_v1_7 before redoing the build, after adding those lines? It looks like the sdkconfig is inconsistent with other settings.

Or, the esp-idf submodule is out of date. Try updating the usbmodules. I use this alias:

alias gitsubupdate='git submodule sync --quiet --recursive && git submodule update --init --filter=blob:none'

[aguaviva]

After a few unsuccessful attempts I deleted everything and started from scratch and same thing. BTW It would help if the sequence of commands to compile the espressif modules where one after the other, otherwise one needs to go fishing around

I just tried this on a clone of adafruit/circuitpython, on the tip of main, in Ubuntu 24.04. It builds for me both without and without the three PSRAM lines in mpconfigboard.mk, doing a make clean in between.

I'm not sure what to suggest trying next. If you are working on your fork, maybe there is something out of date about it. Try building in a clone of adafruit/circuitpython rather than your fork.

I revised the instructions in https://learn.adafruit.com/building-circuitpython/espressif-build slightly yesterday, to update them about python venv's.

[robertoseno]

Thanks DanI will retry with a fresh clone and following your suggestionsIl giorno 23 nov 2024, alle ore 16:15, Dan Halbert ***@***.***> ha scritto: I just tried this on a clone of adafruit/circuitpython, on the tip of main, in Ubuntu 24.04.

Nice comment about the venv I think it is safe to assume people are using venvs these days as it helps keep a clean installation.
Also, I was working on a clone of adafruit/circuitpython, not on main but on the 9.2.1 branch, in Ubuntu 24.04.

Another one is that there are two pages that explain how to build the firmware:

• https://learn.adafruit.com/building-circuitpython/espressif-build (the one you mentioned)
• https://github.com/adafruit/circuitpython/blob/main/ports/espressif/README.rst the one I was using and that might feel more natural as it is part of the repo
  So these instructions might be different and probably conflicting as things tend to get out of sync, so it might be great to have the build instructions in just one place, ideally in the repo as it is there where usually are.

An finally, if all compiled fine for you (it worked for me despite of the warnings) please consider merging #9824
