hi,
I try to use this tool to disable mux for JTAG pin. : devmem
But I have no /dev/mem folder.
hardware : Ubiquity unify AP ( AR7241 + AR9287 )
firmware used : lede-17.01.2-ar71xx-generic-ubnt-unifi-squashfs.bin
If I install openwrt ( openwrt-15.05.1-ar71xx-generic-ubnt-unifi-squashfs.bin ) /dev/mem is present and I have access to memory via devmem or scripts !
I think an option is missing on the lede build.
I can build my own lede ( and openwrt ) firmware, but I don't know what to add to lede build !
I already tried to add these options with no success :
In kernel menuconfig, Device Drivers, Character devices : /dev/mem virtual device support and /dev/kmem/ virtual device support.
Can you help me ?
Thanks in advance
