Hello,
I am trying to integrate the TI WL1271 Wi-Fi module with a custom OMAP-L138 SOM board. We successfully tested the system using EVM modules and Linux kernel v3.3-rc7. I am now trying to get other subsystems running on our custom board with kernel-v3.3-rc7, but I am experiencing problems during USB device initialization. The Linux kernel is failing to enumerate the USB device and assign a user-space interface (i.e. ttyUSB0 ). When I execute "lsusb" nothing is returned. I have verified that VBUS power is applied to the device.
I was previously using kernel v2.6.32-rc6 successfully, but there was no board level support for the WL1271. This seemed to be properly added in v3.3.
Should I expect such problems with this kernel version 3.3 and OMAP-L138? Is CPPI41 DMA still supported for DA8xx devices? I can't seem to remove the MUSB_PIO_ONLY option, which I thought was the cause of this USB issue. At this point, I am curious if this is expected behavior or am I missing a configuration parameter.
Any help would be appreciated.
Thanks!
