Problem when trying to upload the code to arduino UNO from the browser with mLink in Windows 10


#1

Hi, I can perfectly run programs in Live mode to Arduino UNO from google Chrome in Windows 10.
But when I try to upload the code, it doesn’t work and throws the following error:

Command failed: avr-toolchain/bin/avr-g++ -c -g -Os -w -fno-exceptions -ffunction-sections -fdata-sections -fno-threadsafe-statics -MMD -mmcu=atmega328p -DF_CPU=16000000L -DARDUINO=10605 -DARDUINO_AVR_UNO -DARDUINO_ARCH_AVR -I"/app/src/external/arduino/avr-library/variants/standard" -I"avr-library/cores/arduino" -I"arduino-libraries/makeblock/src/" -I"arduino-libraries/makeblock/src/utility/avr/" -I"avr-library/libraries/Wire/src/utility/" -I"avr-library/libraries/Wire/src/" -I"avr-library/libraries/EEPROM/src/" -I"avr-library/libraries/SPI/src/" -I"avr-library/libraries/SoftwareSerial/src/" -I"arduino-libraries/arduino/WiFi/src/" -I"arduino-libraries/arduino/SD/src/" -I"arduino-libraries/arduino/Bridge/src/" -I"arduino-libraries/arduino/Temboo/src/" -I"arduino-libraries/arduino/Servo/src/" -I"arduino-libraries/arduino/Ethernet/src/" -I"arduino-libraries/arduino/TFT/src/" -I"arduino-libraries/arduino/SpacebrewYun/src/" -I"arduino-libraries/arduino/LiquidCrystal/src/" -I"arduino-libraries/arduino/GSM/src/" “/root/mblock-avr/temp/build/code.cpp” -o “/root/mblock-avr/temp/build/code.o” sh: 0: getcwd() failed: No such file or directory /bin/sh: 1: avr-toolchain/bin/avr-g++: not found

Failed to compile file code.cpp

Arduino compile finish.

Any help would be appreciated!

Hi jolosan,
Please download and install the mBlock5 software to your computer and try.
https://www.mblock.cc/en-us/download

By the way, please share me the code that you are trying to upload.
Also please show me a screenshot of the error message.

Yes, I have the same problem too. It must be a recent bug with the online mBlock because it didn’t do this before.

Uploading with the Windows/macOS version of mBlock 5 is fine, but I tend not to use this version since I cannot sign out and sign in with different accounts, unlike the web version.

In the ‘Upload Progress’ window, I get this:

Good news for now: The problem appears to have been fixed! It is now possible to upload code from mBlock via. mLink to the boards again. Many thanks.

@pcmarriott, Good news.
@jolosan, please confirm if your problem also fixed.


#7

Same here. can anybody help?

Hi ericchiu,
Please share me the code that you are using.
I will test it on my side.
Thanks.
