Arduino leonardo infinite uploading on windows 10 - arduino

I'm trying to build a midi controller using an Adafruit Trellis and an arduino leonardo. When it comes to run the code, the uploading status freezes and doesn't complete. I've tried to run a hello world using both an arduinoleonardo and a uno but I still had the same problem. I've deleted the IDE, reinstalled it but nothing has changed. I think it's a driver problem but I actually don't know what to do.

Assuming your Uno is good (no defect), try to plug into a different USB port and try different COM #. Also make sure that you are selecting the correct type of Arduino.

Arduino code uploads fine, however avrdude output is not able to read / verify memory

Purchased some clone Arduino nanos a while ago and finally got to working with them.
Of the 3 i worked with, 2 of them upload and verify fine.
The third is able to upload (code functions properly), however it fails to read flash data.

Here is the output from a clone that worked:

Here is the output from the one with the issue:

What I've done so far:
Reflashed bootloader from working Arduino as ISP
CH340 driver installed
Used (old) bootloader when uploading
Tested on both Linux and OSX
Any suggestions or insight would be much appreciated.
If you have a working UNO or similar board, you could try uploading the bootloader using the Arduino IDE (https://www.arduino.cc/en/Main/Software), and see if you get different results. Sorry, I'm not familiar with using avrdude.
The link on sparkfun gives really good instructions on how to accomplish this task. Scroll about half-way down to where it says Upload Arduino as ISP https://learn.sparkfun.com/tutorials/installing-an-arduino-bootloader/all
Basically, you connect the UNO to your target as shown in the link, then select ArduinoISP in the examples menu, select the COM port and board, and upload the sketch. Then you select your target board in tools, and select Programmer, Arduino as ISP in tools, and finally, Burn Bootloader in tools.
I've had 100% success burning blank Atmega chips using this method.

Should I reinstall nodemcu firmware if I uploaded a arduino sketch?

I have a nodemcu v3 and I'm trying some basic stuff
I installed the esp8266 board in Arduino IDE and then I uploaded a blink example.
But now I'm trying to upload Lua code using ESPLorer but I doesn't work properly. I press in open and set the baud rate to 115200 but I just get some infinite Chinese letters.
Should I reinstall the firmare or something?
There is a very good answers at https://stackoverflow.com/a/43509569/131929 and https://stackoverflow.com/a/47510019/131929.
Should I reinstall the firmare or something?
First you should make up your mind whether you want to conveniently program in Lua or whether you want to stick with Arduino (running on the NodeMCU-clone board). It is an either-or question. Flashing on of them to the module will erase the respective other.
And no, in case you want to use the NodeMCU firmware, you should not use those outdates binaries from 2015. Build a recent version conveniently in the cloud: https://nodemcu.readthedocs.io/en/latest/en/build/.
P.S. if you're interested why I call yours a clone board you may want to read https://frightanic.com/iot/comparison-of-esp8266-nodemcu-development-boards/ from yours truly.
You must erase the flash of your NodeMCU before a new upload. If you ignore that, your software don't run appropriately. To do that, I'm using esptool:
python esptool.py --port COM9: erase_flash
In that example COM9: is the name of my USB/serial interface.
After that you can flash for example your ESP8266 with that line of code to add a boot part:
python esptool.py --port COM9: write_flash -fm dout 0x00000 boot_v1.5.bin
Use the preview line of code and adapt it to upload other parts of the map of the flash memory.

ESP8266 Not running Arduino code when uploaded

I have just recently got some ESP8266's and Ive been trying to use the Arduino IDE 1.8 to program them. (I have also used versions 1.6.5 and 1.6.9).
I have successfully ported a custom build from here and it runs perfectly, I upload Lua code and it runs with no problem.
But when I try to run the Arduino code (Such as the blink example found on this tutorial, with an LED on GPIO 2) that successfully uploads every time, the code never runs. In the Serial program on my PC, I won't see any text, (and the LED will be constantly on).
I followed several online tutorials saying pretty much the same procedure and no luck. Has anyone else experienced this issue and know the solution? Thanks!

Arduino hanging on upload

Getting this when I upload the blink example from the arduino getting started book. The file compiles but just hangs at this point. I have reset, restarted, reinstalled. Nothing seems to work.
It worked just 1 day ago and there have been no changes since.
System wide configuration file is "C:\Program Files (x86)\Arduino/hardware/tools/avr/etc/avrdude.conf"
Using Port : COM5
Using Programmer : avr109
Overriding Baud Rate : 57600
Most of the problems with uploading sketches to Arduino boards come down to communication problems.
Try using other USB ports, check if you selected the correct COM port in the Arduino IDE, also check that you selected the correct board in the IDE.
If all else fails, please check if you can upload the sketch on another PC.
this error might be caused from a mistake in connecting the wires or a problem in the program.So try to check the connection of the wires and if you uploaded the program just because you still don't know how to write arduino codes, I advise you to learn and experiment with the help of the tutorials on the arduino site and reference.I hope that my answer helped you.

Arduino littleBits

I am trying to download code to my littleBits Arduino module on IDE software. I am not able to find the port whenever I am trying to download the image to the board. Is this an internal issue, or an issue with my Arduino board?
You need to check if the arduino serial driver is properly installed in device manager. If arduino serial port is available in Ports then you can download program through IDE
For visual help: https://www.youtube.com/watch?v=4HqXAmV_Ock
Make sure you have proper drivers for your board. In Arduino IDE make sure you are selecting the proper target ie, littleBits Arduino board.
If you are using the Linux system you can use dmesg to see if your system detected the device properly.
If you are using windows system use device manager to make sure your device is properly connected.
Has it ever worked? Did it work for a while then stop?
Reason I ask, I had a problem where the Little Bit suddenly stopped accepting new code. Whenever I tried to download, the Arduino IDE started reporting Unknown USB Device.
Turned out, we had bricked the device. I blogged my steps for recovery here.
Check tools>ports and see if any are available, try them all, (check
while the board is connected)
if none are available check device manager under com ports there should be your device listed if not the you need to reinstall the drivers.
also check if the board is connected correctly (i.e. the connection cord is working properly)
