Hi Guys, I hope this is the right mailing list for help on bugs. Here are the detail: - have kernel 2.6.35.13 running on imx27, trying to use a TL-WN722N dongle (Atheros AR9271). - compiled ath9k_htc (tried both as statically linked and as kernel modules, same problem) - using firmware htc_9271.fw (rev 1.3)...also tried older ones with same result - firmware is loaded successfully by being compiled with the kernel (a menuconfig option, directory /firmware)
- using REG_READ to get device registers returns always the same value: 0x01020101 this is why I get timeout on reading RTC register 0x7044 (probably the first read that uses ath9k_hw_wait function). here is my printout: [ 4.200000] fsl-ehci fsl-ehci.0: Freescale On-Chip EHCI Host Controller [ 4.200000] drivers/usb/core/inode.c: creating file 'devices' [ 4.200000] drivers/usb/core/inode.c: creating file '001' [ 4.200000] fsl-ehci fsl-ehci.0: new USB bus registered, assigned bus number 1 [ 4.200000] fsl-ehci fsl-ehci.0: reset hcs_params 0x10011 dbg=0 ind cc=0 pcc=0 ordered ports=1 [ 4.200000] fsl-ehci fsl-ehci.0: reset hcc_params 0006 thresh 0 uframes 256/512/1024 park [ 4.200000] fsl-ehci fsl-ehci.0: park 0 [ 4.200000] fsl-ehci fsl-ehci.0: reset command 080b02 park=3 ithresh=8 period=1024 Reset HALT [ 4.200000] fsl-ehci fsl-ehci.0: ...powerdown ports...
