Hello,
I applied these commands:
fdtput --type s /boot/dtb-4.12.13-300.fc26.armv7hl/bcm2837-rpi-3-b.dtb /soc/spi@7e204000 status "okay"
fdtput --type s /boot/dtb-4.12.13-300.fc26.armv7hl/bcm2837-rpi-3-b.dtb /soc/spi@7e215080 status "okay"
fdtput --type s /boot/dtb-4.12.13-300.fc26.armv7hl/bcm2837-rpi-3-b.dtb /soc/spi@7e2150c0 status "okay"
And now I see spi_bcm2835 and spi_bcm2835aux modules started, after the reboot. But I can't see my /dev/spi* devices.
Do you have an idea of the missing step?
[root@raspchr-fed26 device-tree]# dmesg | grep spi
[ 93.646629] spi-bcm2835 3f204000.spi: no tx-dma configuration found - not using dma mode
[root@raspchr-fed26 device-tree]#
I still see other devices:
./soc/gpio@7e200000/spi0_gpio35
./soc/gpio@7e200000/spi0_gpio7
./soc/gpio@7e200000/spi1_gpio16
./soc/gpio@7e200000/spi2_gpio40
Do I need to activate them ?
Thanks for your help.
Christophe.
