Espressif ESP32-S3 DevKitC-1-N32R8 #5999

anecdata · 2022-02-09T05:36:59Z

Draft for now. I can't get it to build.

This is the board in the shop. It uses an ESP32-S3-WROOM-2 module. 32MB flash & 8MB PSRAM:

espressif/esp-idf#7670

kmatch98 · 2022-02-15T03:45:17Z

For what it’s worth, I tried the latest ESP IDF version. When running idf.py menuconfig I only see an option for configuring a board with up to 16MB of flash.

See espressif/esp-idf#8365

anecdata · 2022-02-15T04:06:29Z

I had tried to flash N8R8 onto it before and it didn't work. Maybe some param I overlooked is different. But it will flash as a 16MB, so it's usable for now :-)
Adafruit CircuitPython 7.2.0-alpha.2-23-gd4c2ffea2-dirty on 2022-02-14; ESP32-S3-DevKitC-1-N32ishR8 with ESP32S3 Hm, no CIRCUITPY though.

kylefmohr · 2022-03-01T02:17:27Z

Any idea what next steps need to be done to get this working? @anecdata I also tried flashing the CircuitPython firmware for N8R8 on my N32R8 and got the same results, able to get to the REPL, but the CIRCUITPY drive doesn't show up.

anecdata · 2022-03-01T03:35:00Z

@kylefmohr All indications are that we are waiting for Espressif to complete the development discussed in the issue kmatch98 linked above.

kmatch98 · 2022-03-03T05:42:54Z

Possibly some progress here: espressif/esp-idf#7688

anecdata · 2022-03-03T14:54:12Z

Looks like there may still be some 16MB limitations. Do we wait until we update esp-idf, or try to incorporate Espressif's changes into CircuitPython sooner when it's ready enough?

kmatch98 · 2022-07-25T13:23:09Z

More progress here: espressif/esp-idf@04959af

I did not verify whether this was backported to v4.4.

anecdata · 2022-07-31T22:02:38Z

There are indications 32MB+ support is merged into 4.4 (though not sure what snapshot we use). Taking out of draft to see what happens. This is only a test.

tannewt · 2022-08-01T21:43:57Z

There are indications 32MB+ support is merged into 4.4 (though not sure what snapshot we use). Taking out of draft to see what happens. This is only a test.

We're using: https://github.com/adafruit/esp-idf/tree/circuitpython8

tannewt · 2022-11-15T23:20:25Z

@anecdata Do we have 32MB support now an updated version of the IDF? Or will we need IDF 5?

anecdata · 2022-11-18T02:46:12Z

I'm not really sure. If this is still our branch:
https://github.com/adafruit/esp-idf/tree/circuitpython8
We seem to be on 4.4.1?

igrr says here that support is in 4.4.2.

espressif/esp-idf merged / closed PR 7688 (link above) seems to be where the support is added. Issue 7670 is closed (link above), but oddly issue 8365 is still open (link above).

dhalbert · 2022-11-18T02:49:58Z

@anecdata The branch is now https://github.com/adafruit/esp-idf/tree/release/v4.4-circuitpython

anecdata · 2022-11-18T03:02:14Z

I see the "Update version to 4.4.2" comment there, so in theory it should work. I'm not set up to build and test for a while. Also very baffled about the conflicts... I thought I fixed it at one point (basically copying the then-new patterns), but there are a lot more diffs now that I don't grok at all. If someone else wants to jump in sooner, feel free.

anecdata · 2022-11-18T06:35:44Z

Thanks @microdev1!

tannewt · 2022-11-18T17:50:38Z

Does it work now?

anecdata · 2022-11-18T19:30:26Z

I may be flashing it wrong this time around, tried a few ways, but I get a boot loop:

ESP-ROM:esp32s3-20210327
Build:Mar 27 2021
rst:0xc (RTC_SW_CPU_RST),boot:0x18 (SPI_FAST_FLASH_BOOT)

load:0x403c9700,len:0x980
load:0x403cc700,len:0x25a0
entry 0x403c98a4

addendum: I'm able to flash an N8R8 with 8.0.0-beta.4, so I think my config is ok. But I used to be able to flash an N8R8 .bin onto the N32R8 and the REPL would be fine (just no drive), but now that also boot loops. So that's inconclusive... seems like something else may have changed since February to break that.

microdev1 · 2022-11-19T03:39:40Z

@anecdata I just pushed a commit reverting flash mode back to dio, can you do a re-test.

anecdata · 2022-11-19T05:03:10Z

Still boot looping:

ESP-ROM:esp32s3-20210327

rst:0xc (RTC_SW_CPU_RST),boot:0x18 (SPI_FAST_FLASH_BOOT)

The UART shows up correctly as CP2102N USB to UART Bridge Controller, but oddly the USB shows up as USB JTAG/serial debug unit (macOS). No REPL or CIRCUITPY.

microdev1 · 2022-11-19T05:11:47Z

Does the n8r8 definition still boot?
The current board definition is basically the same as n8r8 apart from obvious changes to accommodate 32MB flash.

anecdata · 2022-11-19T05:35:13Z

The N8R8 .bin artifact also boot loops on the N32R8 board. I've tried two N32R8 boards, just to make sure one wasn't flaky, and have erased before flashing each time. Something seems to have changed behind the scenes.

addendum: the 7.3.3 N8R8 .bin does still run REPL on the N32R8 board (and USB shows up correctly as ESP32-S3-DevKitC-1-N8R8), so something else has changed.

jepler · 2023-01-03T20:20:39Z

This might need to pull in espressif/esp-idf#7688 to our esp-idf fork.

microdev1 · 2023-01-26T05:55:40Z

This might need to pull in espressif/esp-idf#7688 to our esp-idf fork.

We now have those commits. This needs a re-test.

I just ordered an ESP32-S3-DevKitC-1-N32R8 and should get it Friday or Saturday.

anecdata · 2023-01-26T14:42:07Z

Erased flash and loaded the bin with esptool.py v4.4. No CIRCUITPY, no REPL. It's boot looping.

The USB connector shows up as USB JTAG/serial debug unit (not good) and repeatedly displays:

ESP-ROM:esp32s3-20210327

rst:0xc (RTC_SW_CPU_RST),boot:0x18 (SPI_FAST_FLASH_BOOT)

load:0x403cc700,len:0x2574
entry 0x403c98a4

The UART connector shows up as CP2102N USB to UART Bridge Controller (good) and repeatedly displays the same block as above.

N8R8 7.3.3 works as before (REPL, NO CIRCUITPY), N8R8 8.0.0-beta.6 also boot loops.

dhalbert · 2023-01-27T17:19:35Z

I got this branch and merged in the latest circuitpython main, which has the latest backports (as of late December) from release/v4.4 in upstream. I erased flash and loaded the .bin. I get:

ESP-ROM:esp32s3-20210327

and it boot loops.

dhalbert · 2023-01-27T18:42:41Z

I'm going to push this to 8.x.x unless we figure something out. It is not urgent for 8.0.0.

microdev1 · 2023-01-28T05:53:24Z

Switched the flash mode to dout:

# Note: we use esptool.py to flash bootloader in
# dio mode for QIO/QOUT, bootloader then upgrades
# itself to quad mode during initialisation
config ESPTOOLPY_FLASHMODE
    string
    default "dio" if ESPTOOLPY_FLASHMODE_QIO
    default "dio" if ESPTOOLPY_FLASHMODE_QOUT
    default "dio" if ESPTOOLPY_FLASHMODE_DIO
    default "dout" if ESPTOOLPY_FLASHMODE_DOUT
    # The 1st and 2nd bootloader doesn't support opi mode,
    # using fastrd instead. For now the ESPTOOL doesn't support
    # fasted (see ESPTOOL-274), using dout instead. In ROM the flash mode
    # information get from efuse, so don't care this dout choice.
    default "dout" if ESPTOOLPY_FLASHMODE_OPI
