Hi! I'm trying to get the Exynos 4210 to work with the BCM4329 wifi module, using SDIO, and with the Android kernel for the Exynos, this works nicely, but with the current kernel (3.2.0-rc1) it doesn't.
After debugging (together with some devs. from Broadcom) it has been narrowed down to: [ 267.175000] brcmf_sdioh_request_word: rw=1, func=1, addr=0x0bf98, nbytes=4 [ 267.175000] mmc1: starting CMD53 arg 957f3004 flags 000001b5 [ 267.175000] mmc1: blksz 4 blocks 1 flags 00000100 tsac 1000 ms nsac 0 [ 267.175000] sdhci [sdhci_irq()]: *** mmc1 got interrupt: 0x00208003 [ 267.175000] before mmc_request_done [ 267.175000] mmc1: req done (CMD53): 0: 00001000 00000000 00000000 00000000 [ 267.175000] mmc1: 0 bytes transferred: -84 [ 267.175000] after mmc_request_done The interrupt above is really weird because it is masked as both a command and data. Summary is as follows: * 3.2.0-rc1; CMD52 read/write and CMD53 read works. CMD53 write fails * 2.6.35.7(android): CMD52 read/write and CMD53 read/write works. Since the brcmfmac driver doesn't exist in the android-kernel, I tried the bcmdhd-driver from the ICS-kernel (after talking to Broadcom devs), and it is the same. It seems like the error is in something else than the wifi-driver, and I'm out of ideas, so any help at all would be appreciated. In advance, thanks! -- Thomas -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
