Thank you. That suggestion worked. I installed a pre-compiled kernel *4.4.27-ti-r62.*
I'm trying to find a kernel which supports these 3 things 1. Runs Xenomai 2. Power management with the wireless adapter (the current issue) 3. Power management features in kernel (CPU freq, CPU idle, Suspend-to-Ram, Runtime PM) With *2*, manually patching and compiling xenomai with an existing Linux kernel from scratch didn't work (gave up due to time constraints). I had to install a pre-compiled kernel* 3.8.13-xenomai-r79 *and then installed the xenomai userspace (xenomai 2.6.4). That worked perfectly. With *3*, I would like to suspend the CPU and then wakeup using GPIO. *Any chance there is a 4.4.x precompiled Xenomai kernel which supports 2 and 3?* Appreciate your help. Took me a while to figure out this wireless issue. Thanks.
