Hi,
I enabled SPI0 in uEnv optargs=quiet capemgr.disable_partno=BB-BONELT-HDMI,BB-BONE-EMMC-2G,BB-BONELT-HDMIN capemgr.enable_partno=BB-SPI0-01 pingroups shows ... group: spi0_pins_s0 pin 84 (44e10950) pin 85 (44e10954) pin 86 (44e10958) pin 87 (44e1095c) end tried the spitest.c with success ./spidev_test /dev/spidev1.0 spi mode: 0 bits per word: 8 max speed: 1500000 Hz (1500 KHz) FF FF FF FF FF FF 40 00 00 00 00 95 FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF DE AD BE EF BA AD F0 0D But my python test script (loop 18-21 patched) doesnt work. Who can I debug deeper ? Or where is my fault ? from Adafruit_BBIO.SPI import SPI import pprint as pp spi = SPI(0,0) spi.mode = 0 spi.msh = 1500000 spi.bpw = 16 spi.open(0,0) print spi.xfer2([0x80,0x50]) spi.close() -> output [[...]] And also I’m not able to use a variable for the result data=spi.xfer2([0x80,0x50]) print data raises a fault also… dmesg says...
