Flashing with esptool #3

Closed hankman13 closed 5 years ago

hankman13 commented 5 years ago

Hi, I just wanted to flash your binary file from the release to an ESP32, but I didn't get it right working. Could you provide the right flashing command for the ESP32? I would like to do this the esptool. Thank you!

Hi, do you have any more informations? Maybe a .bin File i could flash on my ESP?

hankman13 commented 5 years ago

I used the .bin File from the release page. https://github.com/softypit/esp32_mqtt_eq3/releases/download/v1.0/eq3_trv_control.bin

Hi Hankman, Did you get this working? I uploaded the new binary with partition config and bootloader. I have never uploaded directly to the esp so I can't offer any advice there. I always build with the idf tools and upload using 'make flash' from the command line. I believe you should be able to use the esp32 download tool with these files.

Hi softypit, I tried following, I've downloaded the binaries and tried a command which I found in the Ka-Radio32 project.

esptool.py \ --chip esp32 --/dev/ttyUSB0 --baud 460800 --before default_reset \ --after hard_reset write_flash -u --flash_mode dio \ --flash_freq 40m --flash_size detect \ 0x1000 bootloader.bin \ 0x10000 eq3_trv_control.bin \ 0x8000 partitions.bin

But I'm not sure if the address for the binaries is right (just copied and pasted it). Anyway I can see something is running on the serial, and a AP is opened and I can connect. I see the config page for wifi. More I will try later and report it.

So back again. I set up the configuration, but afterwards I'm not sure if its working. Because I got no MQTT Message after all. It would be great if the ESP32 could provide a status webpage with the information of used broker, Wifi SSID and topic name. Will there be any information if I connect it to a serial monitor? (I did not tried out)

softypit commented 5 years ago

Serial monitor will show connection information. This will be WiFi assoc indications, BLE scan results and mqtt connectivity attempts. There should be enough information there to debug any connectivity issues.

hankman13 commented 5 years ago

Thank you for that information, I will recheck my setup.

On a Macbook and default python 2.7 I installed pyserial and esptool with pip and this worked for me:

sudo esptool.py --chip esp32 --port /dev/cu.SLAB_USBtoUART --baud 921600 --before default_reset --after hard_reset write_flash -u --flash_mode dio --flash_freq 80m --flash_size detect 0x1000 bootloader.bin 0x10000 eq3_trv_control-3.bin 0x8000 partitions.bin
