[Arm-dev] RPI / kernel config

[Stephan Guilloux]

OK, thx.

     [root at RPI-C9A58C ~]# ll /proc/config.gz
     ls: cannot access /proc/config.gz: No such file or directory
     [root at RPI-C9A58C ~]# modprobe config
     modprobe: FATAL: Module config not found.
     [root at RPI-C9A58C ~]# modprobe configs
[root at RPI-C9A58C ~]# ll /proc/config.gz
     -r--r--r--. 1 root root 36621 Aug  6 15:31 /proc/config.gz
     [root at RPI-C9A58C ~]# zcat /proc/config.gz | head
     #

     # Linux/arm 4.14.52-v7.1.el7 Kernel Configuration
     #
     CONFIG_ARM=y
     CONFIG_ARM_HAS_SG_CHAIN=y
     CONFIG_MIGHT_HAVE_PCI=y
     CONFIG_SYS_SUPPORTS_APM_EMULATION=y
     CONFIG_HAVE_PROC_CPU=y
     CONFIG_STACKTRACE_SUPPORT=y
     [root at RPI-C9A58C ~]#

Was trying "modprobe config" too, but it's "modprobe configs" ...
Grrr ;-)
