i have MCIMX6SX-SDB (Machine model: Freescale i.MX6 SoloX SDB RevB ) type board with Linux version 4.1.15 (gcc version 5.4.0 20160609 (Ubuntu/Linaro 5.4.0-6ubuntu1~16.04.9)
I try use wi-fi modules Intel 4965AG and Ericsson H039R but no success.
In my starting kernel log i have:
imx6q-pcie 8ffc000.pcie: phy link never came up
imx6q-pcie 8ffc000.pcie: failed to initialize host
imx6q-pcie: probe of 8ffc000.pcie failed with error -22
lspci command returns nothing.
I do not see "pcie treaning sets" ( interrogation on PCIE_TX_N & PCIE_TX_P pins, i try it by osciloscope with 600MHz bandwidth)
in my config file i have options:
#Bus support
#
CONFIG_PCI=y
# CONFIG_PCI_DOMAINS_GENERIC is not set
CONFIG_PCI_SYSCALL=y
CONFIG_PCI_MSI=y
# CONFIG_PCI_DEBUG is not set
