Upload_speed not respected

Development Platforms
1

Hi, i’ve just started using platformio on visual studio code on Mac OS Ventura, but when changing the upload_speed value inside the ini file is not respected.

It fails uploading to an LILYGO TTGO ESP32-Paxcounter LoRa32 .

extract from .ini:

[env:usb]
upload_protocol = esptool
upload_speed = 115200
monitor_speed = 115200

the log displays:

What is the full platformio.ini?

PlatformIO definitely respects upload_speed by passing the wanted value into the esptool.py invocation. For example,

[env:esp32dev]
platform = espressif32
board = esp32dev
framework = arduino
upload_speed = 74880

When doing a verbose upload (project tasks → Advanced → Verbose Upload), it prints

“/home/xxxxxxx/.platformio/penv/bin/python” “/home/xxxxxxx/.platformio/packages/tool-esptoolpy/esptool.py” --chip esp32 --port “/dev/ttyACM0” --baud 74880 […]

Do the same in your project. Does it pass 921600 or 115200? In the first case, another extra_script may have overwritten your upload_speed directive, such as

In the second case (esptool.py gets passed 115200 but stil uses 921600), it’s an esptool.py issue, not PlatformIO.

ok I see baud at 921600 in command.

Looking build.py it uses:

myboard = mykeys["board"]
myuploadspeed = mykeys["upload_speed"]
env.Replace(BOARD=myboard)
env.Replace(UPLOAD_SPEED=myuploadspeed)
print('\033[94m' + "Target board: " + myboard + " @ " + myuploadspeed + "bps" + '\033[0m')

ok found: the related file has a comment in the first lines which declare the value of the upload speed, and it parse that file getting the speed (never seen used a comment as a param but now i manage to upload). Thank you for the support.

Thank you.
