Hello, in my company we are using a Freescale imx35 based platform with a 3.7.6 Kernel. Currently I am trying to get the Silex SX-SDCAN (AR6003) module up and running on this platform. But I have some trouble. The module is connected via sdio. My first try was with the ath6kl_sdio driver module of our kernel (vanilla 3.7.6) which ends in the following error: root@generic-armv6:~# modprobe ath6kl_sdio cfg80211: Calling CRDA to update world regulatory domain cfg80211: World regulatory domain updated: cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp) cfg80211: (2402000 KHz - 2472000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) cfg80211: (2457000 KHz - 2482000 KHz @ 20000 KHz), (300 mBi, 2000 mBm) cfg80211: (2474000 KHz - 2494000 KHz @ 20000 KHz), (300 mBi, 2000 mBm) cfg80211: (5170000 KHz - 5250000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) cfg80211: (5735000 KHz - 5835000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) cfg80211: Calling CRDA for country: DE cfg80211: Regulatory domain changed to country: DE cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp) cfg80211: (2400000 KHz - 2483000 KHz @ 40000 KHz), (N/A, 2000 mBm) cfg80211: (5150000 KHz - 5250000 KHz @ 40000 KHz), (N/A, 2000 mBm) cfg80211: (5250000 KHz - 5350000 KHz @ 40000 KHz), (N/A, 2000 mBm) cfg80211: (5470000 KHz - 5725000 KHz @ 40000 KHz), (N/A, 2700 mBm) ath6kl: temporary war to avoid sdio crc error ath6kl: host only supports scatter of :1 entries, need: 16 ath6kl: ar6003 hw 2.1.1 sdio fw 3.2.0.144 api 3 ath6kl: abi version mismatch: host(0x1), target(0x0) mmc0: Timeout waiting for hardware interrupt. ------------[ cut here ]------------ WARNING: at drivers/net/wireless/ath/ath6kl/sdio.c:487 ath6kl_sdio_irq_handler+0x78/0x84 [ath6kl_sdio]() Modules linked in: ath6kl_sdio(+) ath6kl_core cfg80211 firmware_class ipv6 [<c0014860>] (unwind_backtrace+0x0/0xfc) from [<c03a5fa8>] (dump_stack+0x20/0x24) [<c03a5fa8>] (dump_stack+0x20/0x24) from [<c001ef14>] (warn_slowpath_common+0x5c/0x74) [<c001ef14>] (warn_slowpath_common+0x5c/0x74) from [<c001ef58>] (warn_slowpath_null+0x2c/0x34) [<c001ef58>] (warn_slowpath_null+0x2c/0x34) from [<bf10f56c>] (ath6kl_sdio_irq_handler+0x78/0x84 [ath6kl_sdio]) [<bf10f56c>] (ath6kl_sdio_irq_handler+0x78/0x84 [ath6kl_sdio]) from [<c02cbdec>] (sdio_irq_thread+0x1dc/0x288) [<c02cbdec>] (sdio_irq_thread+0x1dc/0x288) from [<c0041824>] (kthread+0xb4/0xc0) [<c0041824>] (kthread+0xb4/0xc0) from [<c000e5c8>] (ret_from_fork+0x14/0x20) ---[ end trace af8071666a83a3e8 ]--- mmc0: Timeout waiting for hardware interrupt. ------------[ cut here ]------------ WARNING: at drivers/net/wireless/ath/ath6kl/sdio.c:487 ath6kl_sdio_irq_handler+0x78/0x84 [ath6kl_sdio]() Modules linked in: ath6kl_sdio(+) ath6kl_core cfg80211 firmware_class ipv6 [<c0014860>] (unwind_backtrace+0x0/0xfc) from [<c03a5fa8>] (dump_stack+0x20/0x24) [<c03a5fa8>] (dump_stack+0x20/0x24) from [<c001ef14>] (warn_slowpath_common+0x5c/0x74) [<c001ef14>] (warn_slowpath_common+0x5c/0x74) from [<c001ef58>] (warn_slowpath_null+0x2c/0x34) [<c001ef58>] (warn_slowpath_null+0x2c/0x34) from [<bf10f56c>] (ath6kl_sdio_irq_handler+0x78/0x84 [ath6kl_sdio]) [<bf10f56c>] (ath6kl_sdio_irq_handler+0x78/0x84 [ath6kl_sdio]) from [<c02cbdec>] (sdio_irq_thread+0x1dc/0x288) [<c02cbdec>] (sdio_irq_thread+0x1dc/0x288) from [<c0041824>] (kthread+0xb4/0xc0) [<c0041824>] (kthread+0xb4/0xc0) from [<c000e5c8>] (ret_from_fork+0x14/0x20) ---[ end trace af8071666a83a3e9 ]--- Then I used the actual head of the github probject of ath6kl. I checked it out and built a kernel with the sources. The result was a 3.7 kernel, the ath6kl_sdio.ko module and all the other modules. But when I`m trying load the ath6kl module via "modprobe ath6kl_sdio" I get the same error as before with our 3.7.6 kernel. See the log above. Does someone have an idea what`s whats the issue?
