linux – coral dev board hdmi arc Input/output error

I’m trying get the Coral Dev Board to receive audio from my TV over HDMI ARC. I’m pretty sure I have ARC enabled on the TV side but I think there’s something missing on the Coral Linux side. Can anyone help me get this working? Has anyone else got this working?

I modified the phanbell device tree to enable spdif2 and sound-hdmi-arc.

sound-hdmi-arc {
    compatible = "fsl,imx-audio-spdif";
    model = "imx-hdmi-arc";
    spdif-controller = <&spdif2>;
    spdif-in;
};

&spdif2 {
    assigned-clocks = <&clk IMX8MQ_CLK_SPDIF2>;
    assigned-clock-parents = <&clk IMX8MQ_AUDIO_PLL1_OUT>;
    assigned-clock-rates = <24576000>;
    status = "okay";
};

The arc device shows up in Linux but I get an error message when I try to record from it.

arecord -D hw:CARD=imxhdmiarc,DEV=0 -r 48000 -f S24_LE -c 2 -d 3 ~/arc.wav
Recording WAVE '/home/mendel/arc.wav' : Signed 24 bit Little Endian, Rate 48000 Hz, Stereo
arecord: pcm_read:2145: read error: Input/output error

I get the same error message if I connect the Coral Dev Board so some audio test equipment. The command does work if I set an audio equipment setting to disable ARC link negotiation and force the audio to be on. This leads me to believe there’s some kind of link negotiation on the Coral Linux side missing.

Let me know if anybody can help. Thanks.

Does Icelandair board front to back or back to front?

I’m flying Icelandair soon and I’m trying to select a seat. I prefer to board earlier in order to increase the chances of getting overhead bin space. Does Icelandair board passengers in the front seats first, or the back seats?

(It’s a round trip from JFK to Reykjavik, in case this matters.)

real id – Is my US Drivers License valid to board an airplane?

In May, I received a new US State Drivers license. This Driver’s license is not a Real ID, and is marked with NOT FOR FEDERAL IDENTIFICATION. According to TSA RealID Info I believe that this License is valid to be used as identification until 2023.

If I go to a US-Domestic airport, will this Identification be accepted?

How would I find out for sure?

(Background, I also need to renew my passport which is my primary form of identification when boarding a plane. I would like to renew it soon, but then I won’t have it for my next few flights that are coming up).

agile – How does your team manage user stories on the board?

Would like to get your thoughts on this: when working in an agile team, which of the below options works best for you’re team when managing user stories? (and please tell me why if you can). For each feature or CR, do you guys create:

  • 2 Stories – Dev/BA creates a dev story, and UX creates their own design story.

  • 2 Stories – UX creates their design story, and when that’s done, Dev/BA creates a dev story for it.

  • 1 Story – Dev/BA creates just one story with the design tasks and dev tasks part of the same story.

python – Connect4 Game Board (console mode)

I want to connect the def checkForWin function to the board to check for a win. The drawField function combines with the currentField lists to create the board. However, I can’t seem to get the checkForWin function to work with the board.

def drawField(field):
    for row in range(6):
        #i.e. 0,1,2,3,4
                # We map:      0,.,1,.,2
        #if row%2 == 1:
        #newRow = 6  # to convert any float number to integer
        # print(" | | ")
        for column in range(7):  # i.e. 0,1,2,3,4
                                # We map:  0,.,1,.,2 to match our moves columns and rows

        # if column % 2 == 1:
        #     newColumn = int(column / 2)  # to convert any float number to integer

        if column != 7:
            print(field(column)(row), end="")
        else:
            print("")

    else:
        print("")

    Player = 1
    
    currentField = ((" "," "," "," "," "," "),(" "," "," "," "," "," "),(" "," "," "," "," "," "),(" "," "," "," "," "," "),(" "," "," "," "," "," "),(" "," "," "," "," "," "),(" "," "," "," "," "," "))
    
    print(currentField)


    drawField(currentField)
    while(True): # means while(True == True)
        print("Player's Turn: ",Player)
    
        moveColumn = int(input("Please enter a column number (Hint: 0 - 6): n"))
    
        if Player == 1:
            moveRow = 6
            tile = "X"
            for i in reversed(range(moveRow)):
                moveRow = i
            # Make move for Player 1
    
                if currentField(moveColumn)(moveRow) == " ":
                    currentField(moveColumn)(moveRow) = "X"
                    #checkForWin(currentField)
                    break
    
                else:

                        print("Column is full. Select another column: ")
    
    
    
            drawField(currentField)
            Player = 2


        else:
            moveRow = 6
            tile = "O"
            # Make move for Player 2

I need help checking my code, and how best I can link it to the board. I know there are more efficient ways but I want to use the knowledge I have so far to achieve the same results since I am a beginner.

    def checkForWin(field):
        # Checking for horizontal tiles
        boardHeight = len(currentField(0))
        boardWidth = len(currentField)
    
        for y in range(boardHeight):
            for x in range(boardWidth - 3):
                if field(x)(y) == field(x + 1)(y) == field(x + 2)(y) == field(x + 3)(y):
                    print("PLAYER",Player,"WINS!")
                    return
                # else:
                #     continue
    
        # Checking for vertical tiles
        for x in range(boardWidth):
            for y in range(boardHeight - 3):
                if field(x)(y) == field(x)(y + 1) == field(x)(y + 2) == field(x)(y + 3):
                    print("PLAYER",Player,"WINS")
                    return
    
    
        # Checking for positive diagonal tiles (/)
        for x in range(boardWidth - 3):
            for y in range(3, boardHeight):
                if field(x)(y) == field(x + 1)(y - 1) == field(x + 2)(y - 2) == field(x + 3)(y - 3):
                    print("PLAYER",Player,"WINS")
                    return
                # else:
                #     continue
    
        # Checking for positive diagonal tiles ()
        for y in range(boardHeight - 3):
            for x in range(3, boardWidth):
                if field(x)(y) == field(x + 1)(y + 1) == field(x + 2)(y + 2) == field(x + 3)(y + 3):
                    print("PLAYER 1 WINS")
