I’m a developer working with the Atheros AR6003 Wireless LAN chip. I recently updated the Linux kernel on my custom board to 3.0.0 and pulled the latest snapshot of the ath6kl driver from http://git.kernel.org/?p=linux/kernel/git/kvalo/ath6kl-cleanup.git;a=summary (as of 2011-07-25). I’m also using the latest firmware images from http://www.kernel.org/pub/linux/kernel/people/mcgrof/firmware/ath6k.tar.gz as recommended by http://wireless.kernel.org/en/users/Drivers/ath6kl?highlight=%28ar6003%29. After running 'insmod ath6kl.ko', the command line hangs. I’ve narrowed down the execution path to the function ath6kl_bmi_get_rx_lkahd (called from ath6kl_bmi_exeute after loading the OPT firmware). The parameter value of "need_timeout" is set to false. Without this timeout the function never returns. The call to ath6kl_hif_read_write_sync always returns 0, and the value of rx_word is always 0. My question is: What would cause the read from address RX_LOOKAHEAD_VALID_ADDRESS to always return a value of 0? My custom board is using an atmel at91sam9g45 microprocessor using the SDIO bus on mci1. Any information would be greatly appreciated.
