Hi, I am trying to communicate with a device (ADS1299à by using the Beaglebone black but without success. First I have to enable spi dev entries in /dev. There are plenty of blog/tuto which are giving dtc file to generate our own dtbo. But dtc files seems to not be always the same.
In fact I can see that there are already some dtbo files in /lib/firmware : root@beaglebone:~# ls /lib/firmware/ | grep SPI ADAFRUIT-SPI0-00A0.dtbo ADAFRUIT-SPI1-00A0.dtbo BB-SPIDEV0-00A0.dtbo BB-SPIDEV1-00A0.dtbo BB-SPIDEV1A1-00A0.dtbo So I want to use only SPI0 because I know that SPI1 is already used by HDMI. Can I used theses dtbo files ? Is it better to write my own ? It is quite strange, when I enable one of theses dtbo files, I get not only one but two entries in /dev ?? Currently I want to validate my wiring between the two boards. I found a piece of code to read the device id in register of the device though SPI. But when I try to read this register, I can only get 1 or only get 0 (depends of the dtbo files) Any advice of the good way to process here ?
