ESP32 - moved to 16MB version, added default 16MB partition in PIO.INI program crashes

PlatformIO IDE
1

I’ve cloned my project to start using a 16MB ESP32 WROOM instead of the 4MB.
If I compile and flash using the default partition table the 16MB module works fine ( as per 4MB module).
If I add the default 8MB or default 16MB table then the program crashes.

What should I be looking for?
This is the Error ( repeating continuously)

This is the PIO.INI.
The ONLY difference between a working project is the board_build_partitions line being included or not included.
The new module DOES have 16MB as I’ve checked the memory using (ESP.getFlashChipSize());
as well as the module marking.

I have the same issue while using custom board config for esp-wrover-e 16mb Flash

and using this partition

Please correct me if I’m wrong here, but I seem to recall that the ESP32 has a 4MB memory window limit.

Try reducing the app partitions from 6.25MB to 4MB and see if the error still occurs.

Hi rob,
I have the same issue while I using ESP-WROOM-32UE 16MB flash. Do you find the solution of this?

6

hi，i meet the same problem，did you solve it ？ :grinning:

8

You probably have a similar problem, but completely different conditions.
Please post the contents of your platformio.ini!

My actual development board is ESP32S3N16R2 , which is different from adafruit_feather_esp32s3 . Could the board selection be the issue? Even though I’ve already specified flash_size = 16MB , I still get an error.

[env:adafruit_feather_esp32s3]
platform = espressif32
board = adafruit_feather_esp32s3
framework = arduino
board_build.partitions = partition.csv
board_build.flash_size = 16MB
monitor_speed = 115200
board_build.f_cpu = 240000000L
board_build.flash_mode = qio

and while change the official partition table will still report an error，

This is a complex configuration with many potential sources of error! To find the cause of the error, please use a simple “Hello World” sketch with the simplest possible configuration.

Which board do you have exactly?

The correct configuration for an ESP32-S3-N16R2 is

[env:esp32-s3-devkitc-1]
platform = espressif32
board = esp32-s3-devkitc-1
framework = arduino

board_build.arduino.memory_type = qio_qspi
board_build.flash_mode = qio
board_build.psram_type = qio
board_upload.flash_size = 16MB
board_upload.maximum_size = 16777216
board_build.partitions = default_16MB.csv
board_build.extra_flags = 
  -DBOARD_HAS_PSRAM

Additionally you can set a different or custom partition table as well as other flags like

  -DARDUINO_USB_CDC_ON_BOOT=1
  -DARDUINO_USB_MODE=1

and so on.

The ESP32-S3 doesn’t need -mfix-esp32-psram-cache-issue!

12

No error is shown there.
But the log seems to be incomplete.

13

i have esp32s3n16r2， I used the configuration you provided and selected the esp32-s3-devkitc-1 development board environment configuration, and it worked successfully. Was this indeed an issue with the development board environment selection? Previously, I created a new project with the esp32s3box environment, created a new partition file, and flashed it onto the same ESP32S3N16R2 module, but the program would crash. Or, if I used a different development board environment configuration, such as esp32s3n16r8 , the program would run correctly after adding the partition, but it couldn’t find the specified PSRAM.

14

The esp32s3box is using a different PSRAM configuration (octal). That’s the reason why it crashes instantly when the PSRAM is enabled.
