I'm using Jorjin WG7311-2A on my custom board and I also have EVMSK with LBEE5ZSTNC-523(WL1271L). My kernel version is 3.14.0-rc4-12737-gefb78a0-dirty. Where do I get 8.8.0.0.13? AFAIK I'm using the latest firmware from here: https://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/tree/ti-connectivity

This is either wl127x-fw-5-sr.bin or wl127x-fw-5-mr.bin
