 ## Instructions
 
-Using the OpenMV IDE you can run [MicroPython](http://docs.MicroPython.org/en/latest/) scripts on the Portenta H7 board. MicroPython provides a lot of classes and modules that make it easy to quickly explore the features of the Portenta H7. In this tutorial you will first download the OpenMV IDE and set up the development environment. [Here](https://openmv.io/) you can read more about the OpenMV IDE. OpenMV comes with its own firmware that is built on MicroPython. You will then learn to write a simple script that will blink the on-board RGB LED using some basic MicroPython commands.

 ### 4. Creating the Main Loop in the Script
 
-Putting our code inside a while loop will make the code run continuously. In the loop we turn on an LED with `on`, then we use the `delay` function to create a delay. This function will wait with execution of the next instruction in the script. The duration of the delay can be controlled by changing the value inside the parentheses. The number defines how many milliseconds the board will wait. After the specified time has passed, we turn off the LED with the `off` function. We repeat that for each color.

 ### Next Steps
 
 -   Experiment with MicroPythons capabilities. If you want some examples of what to do, take a look at the examples included in the OpenMV IDE. Go to: **File > Examples > Arduino > Portenta H7** in the OpenMV IDE.

 ## Troubleshooting
 
 ### OpenMV Firmware Flashing Issues
 
 - If the upload of the OpenMV firmware fails during the download, put the board back in bootloader mode and try again. Repeat until the firmware gets successfully uploaded.
-- If the OpenMV IDE still can't connect after flashing the firmware, try uploading the latest firmware using the "Load Specific Firmware File" option. You can find the latest firmware in the [OpenMV Github repository](https://github.com/openmv/openmv/releases). Look for a file named **firmware.bin** in the PORTENTA folder.

 - If you experience issues putting the board in bootloader mode, make sure you first update the bootloader to the latest version using the **STM32H747_updateBootloader** sketch from the examples menu in the Arduino IDE.
 - If you see a "OSError: Reset Failed" message, reset the board by pressing the reset button. Wait until you see the blue LED flashing, connect the board to the OpenMV IDE and try running the script again.
 - In bootloader versions 17 and older there was a bug that could put the Portenta into a boot loop when the transmission aborted while flashing a large firmware file. This was fixed in the bootloader version 18.
