I am follow the step from
https://docs.espressif.com/projects/esp ... onfig.html
Perform below command on esp-idf folder :
And then meet problem :
Code: Select all
Unknow CMake command ‘idf_build_set_property’
And find no answer by google also.
I flash the esp32-idf3-20191220-v1.12.bin to a 4M flash esp32 board ,and it work well .
And can't boot when i flash esp32-idf3-20191220-v1.12.bin to a 2M flash esp32 board.
Code: Select all
rst:0x3 (SW_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)
configsip: 0, SPIWP:0xee
clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_drv:0x00,hd_drv:0x00,wp_drv:0x00

load:0x3fff0018,len:4
load:0x3fff001c,len:5012
load:0x40078000,len:10404
ho 0 tail 12 room 4
load:0x40080400,len:5680
entry 0x400806bc
E (540) esp_image: Image length 1339808 doesn't fit in partition length 1114112
;31mE (541) boot: Factory app partition is not bootable
E (543) boot: No bootable app partitions in the partition table

Have a look at the DW2D board configuration -- ports/esp32/board/GENERIC_D2WD and see how it uses partitions-2MiB.csv instead of the regular partition table.
Note that "idf.py menuconfig" isn't part of building MicroPython as it doesn't use the IDF build system.

I had try to flash /build-GENERIC_D2WD/firmware.bin to my 2M esp32 board.
It can flash and verified ok, but still boot on fail.
Code: Select all

configsip: 0, SPIWP:0xee

E (69) flash_parts: partition 3 invalid - offset 0x200000 size 0x200000 exceeds flash chip size 0x200000

Here are the code i perform:
Code: Select all
sudo /home/luke/esp/esp-idf-v3.3.1/components/esptool_py/esptool/esptool.py --chip esp32 --port /dev/ttyUSB0 --baud 2000000 write_flash -z 0xf000 build-GENERIC_D2WD/firmware.bin
And the result here:
Code: Select all
esptool.py v2.8-dev
Serial port /dev/ttyUSB0

Is your chip actually a D2WD though? (i.e. on-chip flash rather than the external spiflash).
I was more just giving example of a config that uses a 2MiB partition table.
You'll likely need to make a board config based on GENERIC with the partition-2MiB.csv file.

The chip on my board is ESP32 D0WDQ6 and link to a external 2M flash
I had try it with partition-2MiB.csv , but fail.

Then you have to create your own board config which uses a partition.csv which matches your needs, because the D2WD board config assumes that the 2MB are embedded.
