Okay. solved.

esptool.py modifies the images before writing. needs and update to a recent version and a parameter for the flash size : --flash_size 16m-c1

why does it modifies the already correctly generated images is another topic ....

i have gui problems with the tool /it's layout is messed up/, so i'm using the command line, which is faster for development.

For 2MB flash i'm flashing with the esptool.py , like this:
./esptool.py --port /dev/ttyUSB0 --baud 115200 write_flash \
0x00000 "firmware/boot_v1.4(b1).bin" \
0x01000 firmware/user1.bin \
0x1fe000 sdk112/bin/blank.bin \
0x1FC000 sdk112/bin/esp_init_data_default.bin

flash addresses are from 2A-ESP8266__IOT_SDK_User_Manual__EN_v1.1.0.pdf .

i've changed the boot to be size 5: /the download tool when combining images does this/
00000000 e9 03 00 50 94 02 10 40 00 00 10 40 74 05 00 00 |...P...@...@t...|
^^^^ size_speed byte
user1.bin is too size 5:
00000000 ea 04 00 50 04 00 10 40 00 00 00 00 f0 14 05 00 |...P...@........|
^^^^ size_speed byte

What i'm missing?

Thanks for your support!

may be related to my spi_flash_* functions problem:
flash_size_map system_get_flash_size_map();
returns 0 which is 256/256 split and is wrong.

gen_appbin.py argument is 5 too. /see my other post/

Hex dump of the start of my user1.bin both irom and iram
00000000 ea 04 00 50 04 00 10 40 00 00 00 00 f0 14 05 00 |...P...@........|

00051510 00 00 10 40 21 ff ff 20 e7 13 c5 22 00 00 00 00 |...@!.. ..."....|

- it is correctly set to 5.
i'm flashing boot_v1.4(b1).bin .
