繼續 LilyGO TTGO T3 LoRa32 868MHz V2.1.6 ESP32 的討論:
I bought two TTGOO-LORA 32 screen prints T3_V1.6 20180606
I saw the video tutorial saying to upload the firmware, so I uploaded ttgo-lora32-v2-us-0.7.11.bin
But now the screen doesn’t show anything. The green light next to the switch also went out.
I’m a beginner. Thanks for your advice
Hi and welcome to community.
If you’re wanting to load the meshtastic firmware, you’ll need to flash the device with the tlora-v2-1-1.6 file of whatever version of meshtastic you’re choosing to flash.
The V2-1-1.6 board (label T3_V1.6 frequently) is a bit different than the previous V2 version of the board, which I believe has different pin mappings. That’s most likely why you’re seeing those issues.
Thebentern Hi! Thank you for your reply.
How do I flash the device?
Could you please give me some more guidance?
Is there a video tutorial?
Step 7
Can you check that you have the device driver installed? Right click on the start button and select Device Manager, then look at the ports section, you should see something like this.
If it doesn’t say Silicon Labs CP210x… then you need to install that device driver by visiting https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers
apt105
Great contributor
Hello, I install Silicon Labs CP210xUSB on my PC
The error cannot be resolved!
Can you try running ESPFlasher as admin? I’m not sure why it’s giving you a permission error. Are there any other devices attached to serial ports?
You’re still choosing the wrong file. Choose…
Firmware -tlora-v2-1-1.6-1.2.16.bin
Not sure if this will affect your permission issue but try and see what happens.
You should not need to “scrub” the current firmware, just follow the first time install directions.
Now firmware-ttgoo-lora32-v2-us-0.7.11.bin does not boot, what do I do?
How should I use the new one? Request help, thank you
Download from here
https://github.com/meshtastic/Meshtastic-device/releases/download/1.2.17/firmware-1.2.17.zip
Unzip and use the file
firmware-tlora-v2-1-1.6-1.2.17.bin
Download the latest ESPHome Flasher for your operating system
Connect your radio to your PC via USB and then open ESPHome Flasher. Choose the com port. It should automatically be in the drop down
Click Browse and select the firmware for your board from the package we just downloaded.
firmware-tlora-v2-1-1.6-1.2.17.bin
Click Flash ESP and wait until it’s finishing flashing the board.
I run into kind of the same problem.
My workaround is this:
first.
esptool.py erase_flash
download and unzip firmware 1.0.0
cd firmware-1.0.0
and in my case cuz im in EU:
./device-install.sh -f firmware-tlora-v2-1-1.6-EU865-1.0.0.bin
then download and unzip firmware firmware-1.2.28
cd firmware-1.2.28
./device-update.sh -f firmware-tlora-v2-1-1.6-1.2.28.bin
and this from the same firmware-1.2.28 folder, if you want the web part to work again:
esptool.py --baud 921600 write_flash 0x1000 system-info.bin
esptool.py --baud 921600 write_flash 0x00390000 spiffs-1.2.28.bin
Cheers,
Frank
ahh ok you are on windows and a gui. I missed that.
try downloading the 1.0.0 version first and install the firmware-tlora-v2-1-1.6-US-1.0.0.bin if you are in US.
then next download and update with the new version firmware-1.2.28 called firmware-tlora-v2-1-1.6-1.2.28.bin.
Hello, I have the 2.1.1.6 version of this board. When I run esptool.py erase_flash, i get the error failed to create process. Any suggestions?
Thanks!
Do you have the serial driver installed and verified it’s working?
