Go dead loop using large partions with lastest realeases (4.2.0 ~ 4.3.0 )- no issue with arduino ide or old version (1.0.1)

Hi, Thank you for the 4.3.0 to support latest esp32-arduino 2.0.3, I have issue that did not happen with older releases neither with arduino IDE. I have checked doc and usage seems not changed so I am guessing there is a bug.

I am using unmodified wifiAccessPoint.ino from esp32-arduino sample as MCVE and just add platformio.ini to use 16MB partition because my board has 16MB flash My board is a FYSECT E4 with 16MB flash, so I use esp32dev board, I have also checked with another board I have : Lolin32Pro 16MB flash.

Here the configuration file I use

[platformio]
default_envs = esp32dev

[env:esp32dev]
platform = espressif32@4.3.0
;platform = espressif32@1.0.1
board = esp32dev
framework = arduino
monitor_speed = 115200
board_build.f_cpu = 240000000L
board_build.f_flash = 80000000L
board_build.flash_mode = qio
board_build.partitions = default_16MB.csv
upload_speed = 115200
monitor_speed = 115200

I use the default_16MB.csv from esp32-arduino core, but same behavior happen with default_8MB.csv and ok with default 4MB

# Name,   Type, SubType, Offset,  Size, Flags
nvs,      data, nvs,     0x9000,  0x5000,
otadata,  data, ota,     0xe000,  0x2000,
app0,     app,  ota_0,   0x10000, 0x640000,

spiffs,   data, spiffs,  0xc90000,0x370000,

Then with 4.3.0 I go to dead loop reboot after flashing

Configuring access point...

Is it a bug ? or do I miss new setting that is not clearly documented? I enclose the MCVE WiFiAccessPoint.zip

@valeros board_upload.flash_size = 16MB did the trick thank you I think it worth a note in https://docs.platformio.org/en/latest/platforms/espressif32.html @Jason2866 thank you for the help too

[valeros]

It should be board_upload.flash_size = 16MB not board_build.flash_size = 16MB.
