I changed baud rate to 115200. Now I can connect via UART on this speed on linux.
On the commit 0049b5d615f233b82d3ac4005fe9b85535e758cb the value of parameter UART_BAUT_RATIO was changed from 115200 to 74800. I don't know exactly why it was necessary, but currently everything works well. Thank you.

I have merged your achievement, thanks very mush for what you did for mesh.

Now I can debug why it is problem with connection (flush ssid: pwd:@▒▒?@▒▒?) - it don't recognize my ssid..., but this is case to another topic.

In conclusion, I try on 3 machines (2 linux based and one with windows installed) to upload firmware on various methods (using esptool and espressif gui tool for windows). All methods of downloading firmware work correctly. The problem is with connecting via UART on machines with linux. I used putty on linux and windows and I get reasonable information only on windows. On linux I tried also another software: minicon (which is recommended by espressif) but it dosn't suport baud rate 74880, cu but I get the same "rubbish" as when I use putty. What is strange I have some devices with firmware created a few days ago (baud rate 115200) and I can connect to it by putty in linux. Probably it's bug.

you can modify the UART_BAUT_RATIO to support 115200.

Than I connect via putty on speed 74880.

Do you have any other idea?

Sorry, I have no idea.
Tomorrow, i shall schedule another guy to try to fix the problem.

1. please use 115200 to download default.init.bin, blank.bin, boot.bin, user1.bin
2. use 74880 to get txt information about com.

I set parameters as you told but it still don't work correctly.
To download firmware I use commands as follows:

Code:

sudo python ~/esp-open-sdk/xtensa-lx106-elf/bin/esptool.py --port /dev/ttyUSB0 erase_flash

Code:

sudo python ~/esp-open-sdk/xtensa-lx106-elf/bin/esptool.py --port /dev/ttyUSB0 write_flash -fm qio -fs 8m -ff 40m 0xfc000 ~/ESP8266_MESH_DEMO/bin/esp_init_data_default.bin

Code:

sudo python ~/esp-open-sdk/xtensa-lx106-elf/bin/esptool.py --port /dev/ttyUSB0 write_flash -fm qio -fs 8m -ff 40m 0xfe000 ~/ESP8266_MESH_DEMO/bin/blank.bin

Code:

sudo python ~/esp-open-sdk/xtensa-lx106-elf/bin/esptool.py --port /dev/ttyUSB0 write_flash -fm qio -fs 8m -ff 40m 0x00000 ~/ESP8266_MESH_DEMO/bin/boot_v1.4\(b1\).bin

Code:

sudo python ~/esp-open-sdk/xtensa-lx106-elf/bin/esptool.py --port /dev/ttyUSB0 write_flash -fm qio -fs 8m -ff 40m 0x01000 ~/ESP8266_MESH_DEMO/bin/upgrade/user1.1024.new.2.bin

There are binary files which I download to esp device: http://rojek.cc/esp_firmware.zip

Do you have any idea what's wrong?

Only change was that I get user1.1024.new.2.bin, not user1.1024.new.1.bin due to that spi size and map: 1024 (512KB + 512KB) is option 2 not 1.
Then I take esp device and upload firmware on it (using esptool.py on Linux and ESP8266 Flash Download Tool for Windows). Devise don't connect to my AP and when I connect it to UART I get response as on the image below:

I try to connect to it on different speeds as follows: 9600, 115200, 74880.

What should I do to upload id correctly?

Download speeds is 115200
UART speeds is 74880
