Flashing error / Lilygo T-Beam ESP32 v1.2 / psRam/v8.0.0

[emge65]

Tried to flash my T-beam as described in the user guide document without success.
Maybe there is a bug, or I did something wrong or the new v1.2 board is not supported also.

/psRam/ is the correct directory for T-beam, I guess ?!

In the v8.0.0 folder is no boot_app0.bin!
I used the one i found in the "/master/bin"

T-beam spec.:
MCU: Esp32
Flash: 4MB
PSRAM: 8MB
Serial Chip: CH9102
PMU: AXP2101
868Mhz, Soldered Oled

USB port: serial ch9102 (COM11)

Flash Tool 3.9.7

Got this error:

Uploading stub...

Not sure why this overlap is coming up. An alternative flashing method is using Chrome and https://espressif.github.io/esp-launchpad/. Just connect, then DIY, add your files and flash ...

Hi,
Tried to flash it today with settings in bin-folder (GxAirCom/bin/psRam/flash_settings.png) and it worked out of the box.
Also tried it with the link from @emge65 and it worked.
Have you choosen ESP32 as ChipType ?

[emge65]

Servus Gerald,
yes, i used the settings as shown in "flash_settings.png". (see image)
and chose the ESP32. Did everything carefully with double check, because i am not a coder, just good in hang gliding 😉
Tried the web interface flash tool and got an error msg too. "offset field is not a valide Adresse" (see video)
Changed the usb cable, changed the file path, checked the file permission, jumped around the computer, thought this could maybe help 😁

You need to enter the addresses in hex format, e.g.

• 0x1000
• 0x8000
• 0xE000
• ...

yea, recognized this already. (by myself) but thank you...

Looks like the upload worked without errors.
Just i do have problems to restart the board. Unplugged the usb, plugged in again, tried on/off. Screen is still black.
Flashing log last line shows "hard resetting via rst pin..."

Now it is time for you to read the manual, p.10/10:

Configuration Menu for GXAirCom
You can enter the configuration menu of GXAirCom in order to set or change some parameters
according to your needs, or even use the “send messages” feature of the device to send short
messages to other pilots using GXAirCom and LK8000.
To access the configuration menu follow this steps:

1. Power on the GXAirCom
2. 3. Search for available wifi on your phone (or pc) and select GXAIRCOM-XXXXXX
      Connect to the network using 12345678 as default password (you can change it on the
      settings but is not recomended as if you lose it you need to do a full flash). The phone
      could show a message saying internet is not available. Ignore the message and keep
      the connection (Wifi icon on the phone will show an exclamation mark).
3. Open up the browser and type 192.168.4.1 on the address bar and navigate to it (enter,
   go, ok).
   You will see the configuration menu on the screen.

In the settings you then can enable the OLED.

Hi, perfect simple to understand description.
Just, my phone and the laptop does not find the wifi. Google can not help me...
Red led below the screen is on.
By the way, i did a meshtastic flashing last week, everything was fine, connection to phone and app did work.

If you can solve this, i will send you a 🍺

Let's try it over the phone, just drop me an email: [email protected] and then let's continue there. Where are you based? I am based in Bavaria ...

[emge65]

Jep, super, will drop you an mail...
Thank you!

[emge65]

Flashing problem fixed!😁
It was more as simple!
Big thanks to VirusPilot!
As first time user of GitHub, i did download the bin files with mouse right click, "link save as..." as usual...
(don't blame me🤦‍♂️ )
It might be helpful to note this in the GxAirCom installation document, to avoid this "stupid trap".
