Wrong build size when using custom factory and ota partitions

[kostuch]

I try to build for setup when I have custom small app factory partition and two ota. CASE1: When partition table has only factory partition, the compilation size reflect the partition size CASE2: When I add one or two ota partitions, the build (and probably upload) reflect the ota partition size. The code is just empty setup() and loop().

platformio.ini

[env:esp32-c3-devkitm-1]
platform = espressif32
board = esp32-c3-devkitm-1
framework = arduino, espidf
board_build.partitions = part_table.csv

part_table.csv

nvs,      data, nvs,     ,        0x4000,
otadata,  data, ota,     ,        0x2000,
phy_init, data, phy,     ,        0x1000,
factory,  app,  factory, ,        512K,
#ota_0,    app,  ota_0,   ,        1M,   #at this moment commented out and everything is fine
#ota_1,    app,  ota_1,   ,        1M,

After uncomment ota definition in part_tables.csv and build again

Setting offset to 0x10000 for factory makes no change to this behavior. This is for esp32c3, but for esp32 I have same situation. What can be done to force build and upload to factory partition, but have also ota deifinitions?

Thanks for reporting, should be fixed in the development branch.

@valeros Thank you for the immediate patch. How about flashing in such case? Will it also set the factory partition as a target for upload?

Flashing is completely different process, the default address for application is set to 0x10000 and is not affected by the values from the partition file.
