Thank for this quick answer, So I have remove the line cape_disable=capemgr.disable_ partno=BB-BONELT-HDMI,BB-BONELT-HDMIN,BB-BONE-EMMC-2G
In addition yes I have connected the PIN P9_29 (spi1_d0) and P9_30 (spi_d1) And I'm trying to use the derek molloy program : https://github.com/derekmolloy/exploringBB/tree/master/chp08/spi/spidev_test ./spidev_test -D /dev/spidev2.1 and also ./spidev_test -D /dev/spidev2.0 However I'm alway having the answer : spi mode: 0 bits per word: 8 max speed: 500000 Hz (500 KHz) 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 And I'm supposed to received bits per word: 8 max speed: 500000 Hz (500 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 I received this when I do that with SPI0 and connected P9_18(spi0_d0) and P9_21(spi0_d1) So I still don't get where did the problem come.
