Circuitpython 9.2.1 fails to run on EPS32P4-Function-EV board

[ralphrmartin]

CircuitPython version

9.2.1 for ESP32 P4
Also tried later development versions with the same outcome.

Code/REPL

Didn't get a repl

Behavior

After successfully flashing circuitpython 9.2.1 (for esp32 p4) using esptool, I get no repl, and the serial monitor just shows

SP-ROM:esp32p4-eco2-20240710
Build:Jul 10 2024
rst:0x10 (CHIP_LP_WDT_RST),boot:0xf (SPI_FAST_FLASH_BOOT)

repeatedly.

Description

Using ESP32 P4 Function EV board with connected camera and lcd.

Additional information

I also cannot get a repl using thonny.

[ralphrmartin]

I have successfully run esp's own examples for the board, so the hardware is OK.

Did you erase the flash before loading the .bin?

Try 9.2.0 from here: https://adafruit-circuit-python.s3.amazonaws.com/index.html?prefix=bin/espressif_esp32p4_function_ev/

[ralphrmartin]

Yes, I erased the flash first. I get the same result with 9.2.0.

In Thonny it reports

Device is busy or does not respond. Your options:

  - wait until it completes current work;
  - use Ctrl+C to interrupt current work;
  - reset the device and try again;
  - check connection properties;
  - make sure the device has suitable MicroPython / CircuitPython / firmware;
  - make sure the device is not in bootloader mode.

but I get the same after pushing RST.

[ralphrmartin]

The latest version does not work either.

[ralphrmartin]

Further info - the web installer does not recognise the chip,

Detecting chip type... unknown!
Error: Cannot read properties of null (reading 'getChipDescription')

so I used e.g.
esptool.py --port /dev/tty.usbserial-210 write_flash -z 0x0 /Users/ralph/Downloads/adafruit-circuitpython-espressif_esp32p4_function_ev-en_US-9.2.0.bin

[dhalbert]

@tannewt has this board and did the port. I don't, unfortunately, so I think we'll have to wait for his return from break in early January.

I loaded 9.2.1 by connecting to the type C connector labeled: USB-UART and running this command:

python ~/micros/bin/esptool.py --chip esp32p4 --port /dev/ttyUSB0 write_flash -z 0x0000 ~/Downloads/adafruit-circuitpython-espressif_esp32p4_function_ev-en_US-9.2.1.bin

After the firmware was flashed I was able to connect to the REPL using tio on the /dev/ttyUSB0 port. If after flashing the firmware I connected to the type C connector labeled USB-OTG no serial port was created and of course the CIRCUITPY drive didn't show up presumably because that PR hasn't been merged in to "stable" yet.

I also loaded the "Absolute Newest" via the USB-UART type C connector using:

python ~/micros/bin/esptool.py --chip esp32p4 --port /dev/ttyUSB0 write_flash -z 0x0000 ~/Downloads/adafruit-circuitpython-espressif_esp32p4_function_ev-en_US-20241222-main-PR9906-53f76c5.bin

After which, the REPL was not available on the created /dev/ttyUSB0 port, but if I plugged into the type C connector labeled USB-OTG the port /dev/ttyACM0 was created and provided REPL access. Also the CIRCUITPY drive was mounted.

Edit: I have the Camera and LCD disconnected so if you can't get the REPL using the connectors I was using, perhaps try disconnecting the peripherals.

[ralphrmartin]

Before starting, I had the P4 on /dev/tty.usbserial-210 when plugged into the USB-UART.
I downloaded using
esptool.py --chip esp32p4 --port /dev/tty.usbserial-210 write_flash -z 0x0000 /Users/ralph/Downloads/adafruit-circuitpython-espressif_esp32p4_function_ev-en_GB-9.2.1.bin
After downloading, I checked for other serial ports, but I could only still see /dev/tty.usbserial-210, with no REPL. I can see no tty on connecting to the USB-OTG port. Doing
screen /dev/tty.usbserial-210 115200
gives no REPL, just the output reported above.

After again erasing flash, I tried doing the same again, but with the latest version
esptool.py --chip esp32p4 --port /dev/tty.usbserial-210 write_flash -z 0x0000 /Users/ralph/Downloads/adafruit-circuitpython-espressif_esp32p4_function_ev-en_US-20241222-main-PR9906-53f76c5.bin
with the same result: no tty on the USB-OTG port, and no REPL on /dev/tty.usbserial-210. Also the the CIRCUITPY drive did not show up.

This is all under MacOS 15.2, in case that matters.

[ralphrmartin]

Furthermore, I am using esptool from esp-idf 5.5, in case that is relevant.

[ralphrmartin]

My ESP-32 P4 board is version v1.4

[ralphrmartin]

I tried disconnecting the display, but it made no difference. (I didn't want to disconnect the camera as I dont want to risk mangling the fragile edge connector). I also tried adding external power on the usb-c POWER-IN port, but that did not help.

[dhalbert]

So something is different. It sounds like you are using the same ports, but here's a picture -- maybe you can both describe exactly which ports you are using:
(from https://docs.espressif.com/projects/esp-dev-kits/en/latest/esp32p4/esp32-p4-function-ev-board/user_guide.html)

What is the version number printed on the board?
What is the part number of the ESP32-P4?
What is the part number of the flash chip that's on the board?

I don't see any jumpers to change.
