lyrat 4.3 schematic

[benbiles]

does anyone know what the pins are used for on lyrat 4.3?
Are they unconnected because they are 1.8v only ?

SPI_SD0
SPI_SD1
SPI_SD2
SPI_SD3
SPI_CMD
SPI_CLK

the TF_CARD uses these pins shared with JTAG connector
IO15
IO14
SD_IO13
SD_IO12
IO4
IO2
IO34

I removed the SD card and removed the 10k pullups so I can configure these pins for SPI an external peripheral.
IO15
IO14
IO4
IO2
IO34 maybe but input only

just wondering why these were not used for the SD CARD , avoid a logic level translator translator?
SPI_SD0
SPI_SD1
SPI_SD2
SPI_SD3
SPI_CMD
SPI_CLK

Those pins are used for the internal flash and can't be used for SD cards.

OK, thanks. I'll stick to using the SDCARD IO pins as I might need JTAG debugger

EDIT: Just in case anyone else is looking to add a SPI port and use JTAG debugger , IO12 and IO13 ( SD card slot CMD and CLK) are used by JTAG so best scavenge a few GPIO pins from switches or touch pads that are 3.3v capable and IO ( not input only )
