According to elinux
GPIO 8-11 is indeed for the I2C/SPI slave function on the RPi4.
GPIO 10: I2C_Slave_SDA
GPIO 11: I2C_Slave_SCL
GPIO 32-33 UART0 for BT
GPIO 34-38 SD1 for Wifi
GPIO 42 GPCLK1 for Ethernet 25MHz output
GPIO 43 GPCLK2 for Wifi 32kHz output
GPIO 128 BT_ON
GPIO 129 WL_ON
How did you get that? The firmware dt-blob.dts on github has not yet been updated.gregeric wrote:Looks real enough to me, and matches what I see in firmware.
