Crashing on begin() on MatrixPortal S3

[JetForMe]

I've got an Adafrui MatrixPortal S3 and 64x32 display that I had working with CircuitPython and rgbmatrix, but now I'm trying to do this with ESP32-HUB75-MatrixPanel-I2S-DMA and it gets into a reboot loop when I call begin(). I'm setting it up similar to one of the examples, like this:

static const uint8_t	kPinR1			=	35;
static const uint8_t	kPinG1			=	34;
static const uint8_t	kPinB1			=	33;
static const uint8_t	kPinR2			=	31;
static const uint8_t	kPinG2			=	32;
static const uint8_t	kPinB2			=	30;
static const uint8_t	kPinA			=	26;
static const uint8_t	kPinB			=	29;
static const uint8_t	kPinC			=	25;
static const uint8_t	kPinD			=	28;
static const uint8_t	kPinE			=	23;
static const uint8_t	kPinLatch		=	24;
static const uint8_t	kPinOE			=	22;
static const uint8_t	kPinClock		=	38;

MatrixPanel_I2S_DMA*	gDisplay;
uint16_t				gRed;

void setup()
{
	HUB75_I2S_CFG::i2s_pins pins={kPinR1, kPinG1, kPinB1, kPinR2, kPinR2, kPinB2, kPinA, kPinB, kPinC, kPinD, kPinE, kPinLatch, kPinOE, kPinClock};
	HUB75_I2S_CFG displayConfig(
		64,		// module width
		32,		// module height
		1,		// Chain length
		pins
	);

	gDisplay = new MatrixPanel_I2S_DMA(displayConfig);
	gDisplay->begin();
	//gDisplay->setBrightness8(40); //0-255
	//gDisplay->clearScreen();

	//gRed = gDisplay->color565(255, 0, 0);
	
	//gDisplay->fillScreen(gRed);
}

There’s nothing else going on on the chip except blinking an LED in the lop and some `Serial.println` during setup. Am I missing some config step?

Aaand I'm an idiot. I used the pin numbers, not the GPIO numbers. It should be:

static const uint8_t	kPinR1			=	42;
static const uint8_t	kPinG1			=	41;
static const uint8_t	kPinB1			=	40;
static const uint8_t	kPinR2			=	38;
static const uint8_t	kPinG2			=	39;
static const uint8_t	kPinB2			=	37;
static const uint8_t	kPinA			=	45;
static const uint8_t	kPinB			=	36;
static const uint8_t	kPinC			=	48;
static const uint8_t	kPinD			=	35;
static const uint8_t	kPinE			=	21;
static const uint8_t	kPinLatch		=	47;
static const uint8_t	kPinOE			=	14;
static const uint8_t	kPinClock		=	 2;
