Data log on Ubuntu #2

Closed shawnlobo96 closed 7 years ago

shawnlobo96 commented 7 years ago

How to get data log on Ubuntu? After searching through the code I managed to get it working. Please mention in the wiki that the WiFi credentials have to be added in the user_main.c file. Great job on the code gotta say that!

By data log do you mean serial debug output?

Also, could you please care to elaborate how you fixed the issue mentioned in an earlier edit of this issue?

I was successful in building the ESP8266-HomeKit and ESP8266-HomeKit-Demo and got the two files "eagle.flash.bin" and "eagle.irom0text.bin". On running the esptool flash tool, the files were successfully written to the ESP8266 NodeMCU 1.0 at the addressed "0x00000" and "0x14000". After resetting (pressing the reset button) the board, the led on the NodeMCU board kept flashing rapidly and writing gibberish data to the serial monitor on the Arduino Serial Monitor. I wasn't able to get it running. What could be the problem? Is there any configuration that I may have missed?

Wifi instructions added, good point! As for Ubuntu serial programs, try Coolterm. Realise that it needs to support 74880 baud which is not obvious. Coolterm can if adding a special file (see its help files).

Please confirm if it worked?

@AdySan I managed to get it working on NodeMCU 1.0 by following the below steps:

  1. Following the build steps for ESP8266-HomeKit, I successfully generated the two files libhkc.a and hkc.h
  2. Assuming that you have previously cloned the ESP8266-HomeKit-Demo repository, switch to the ESP8266-HomeKit-Demo repository $ cd ../ESP8266-HomeKit-Demo
  3. Edit the user_main.c file located in ESP8266-HomeKit-Demo/user/ to set the WiFi credentials.
  4. Uncomment the user_init routine (line 197 of user_main.c file) and fill in the SSID and password of your home network.
  5. After saving the file, follow the build instructions as stated in the ESP8266-HomeKit-Demo wiki.
  6. Following the above step, running $ ./gen_misc.sh should create two files eagle.flash.bin and eagle.irom0text.bin in the bin directory.
  7. Connect the ESP8266 NodeMCU 1.0 (or equivalent chip) to the computer.
  8. Erase the flash using the command $ esptool.py -p /dev/ttyUSB1 erase_flash (*set the appropriate port)
  9. Write the file blank.bin and esp_init_data_default.bin to the address 0x3fe000 and 0x3fc000 (or other addresses depending upon the flash size).$ esptool.py --baud 230400 -p /dev/ttyUSB1 write_flash 0x3fe000 bin/blank.bin 0x3fc000 bin/esp_init_data_default.bin (*set the appropriate port) (the files blank.bin and esp_init_data_default.bin** come along with ESP8266_RTOS_SDK and is present in the bin directory)
  10. Following the above step will prevent the module from rebooting/crashing.
  11. Finally flash the two generated files eagle.flash.bin and eagle.irom0text.bin at the address 0x00000 and 0x14000 respectively $ esptool.py --baud 230400 -p /dev/ttyUSB1 write_flash 0x00000 ../bin/eagle.flash.bin 0x14000 ../bin/eagle.irom0text.bin (*set the appropriate port)
    1. After the two files are flashed to the module, I reset the module by pressing the reset button. After a few seconds, a new accessory should show up in the Home App.

Some of the main steps I followed and weren't mentioned in the wiki page were step 3 and step 9

Hope this helps! Please let me know if it worked or didn't for you.

Yep @AdySan serial debug output. @HomeACcessoryKid I tried using PUTTY and set the baud rate to 74880 but it returned gibberish data.

AdySan commented 7 years ago

@shawnlobo96 Thanks for the recovery procedure after erasing flash, I'll update the wiki.

Regarding the It is possible your USB-Serial chip doesn't support that baud rate for some reason, can you try changing the default baud rate in the SDK?

Hello, I am having kind of a problem getting the code run, I forked the repository and followed the travis instructions, it looks it generates some kind of binary but when I connect it to a serial console, all I can see is this:

ets Jan 8 2013,rst cause:2, boot mode:(3,6)

load 0x40100000, len 29960, room 16 tail 8 chksum 0x42 load 0x3ffe8000, len 2860, room 0 tail 12 chksum 0xff ho 0 tail 12 room 4 load 0x3ffe8b40, len 4528, room 12 tail 4 chksum 0xd7 csum 0xd7

Any ideas on what step I did wrong? the only step I didn't follow is 1) from @shawnlobo96 because I ran a travis build

I think you should first check your setup and get a hello world to work. There are many places that explain how. Consider starting from scratch…
