How to Erase my MCU (RA4M2)?
I might be incorrect, but unfortunately it seems like your MCU is locked forever, I hope to be incorrect, and probably my associates will correct me also, but seems like you accidentally set one of those bits in your FW and therefore locked your MCU. Can you recall the sequence of operation and optiRead more

I hope to be incorrect, and probably my associates will correct me also, but seems like you accidentally set one of those bits in your FW and therefore locked your MCU.
See lessCan you recall the sequence of operation and options that you used to flash you MCU the first time? perhaps this will help to understand what have happed.

See lessDoes Alexa solution have certain requirements for environmental noise?
The current Espressif voice solution can meet the environmental requirements of a signal-to-noise ratio of less than 5dB, and for some fixed noise scenarios, it can also be less than 0dB (need to be optimized for the actual product).

Hi,
To install the Arduino extension enter “Cntrl+Shift+x” to display the Extensions viewer and type “vscode-arduino” into the search bar. This should return just one result. Press the “Install” button to install.
Not all VS Code’s functionality is accessible via menus. Instead, VS Code has a command-line-type facility for interfacing with extensions called the Command Palette.
To run the Command Palette, type “Cntrl+Shift+p” to display a drop-down box that you can enter commands in. Type “Arduino Examples” into the command palette and press return. This will open up a link to the familiar example projects – navigate to “01.Basics” and then double click on “Blink” to open the world-famous Blink project.
We need to change a few system settings before we can start programming. All of these can be accessed via VS Code’s interface.
Once you have opened up an Arduino .ino file, VS Code reconfigures in an Arduino mode, and gives access to special functionality in its bottom blue margin, as shown in the image below.
Click on <Select Programmer> and select AVR ISP (Arduino AVR Board)
Click on <Select Board Type> and select Arduino/Genuino Uno
To set the serial port that VS Code will communicate with your Arduino Uno we need to open up the Command Palette (Cntrl+Shift+p) and then type “Arduino Select Serial Port”. You should then select which USB port your Uno is connected to.
Hope its clear.
