The card chokes for some reason and times out when it's supposed to receive a chunk of the firmware. Odd, as the loading loop first queries the card if it is ready for more data. > > You could try adding a delay to the helper firmware loading loop (if_sdio_prog_helper() in if_sdio.c). Add an msleep(100); in there and see if that gets things further. Loading will be slow as hell though. OK, that seems to at least change the failure a little :) I added an msleep after line 466 of if_sdio.c (at the very bottom of the loop). Now I don't get the final "32 bytes transferred: -110" error: Nov 15 11:52:31 pequin kernel: mmc0: req done (CMD53): 0: 00002000 00000000 00000000 00000000 Nov 15 11:52:31 pequin kernel: mmc0: 64 bytes transferred: 0 Nov 15 11:52:31 pequin kernel: mmc0: starting CMD53 arg 9a000002 flags 000001b5 Nov 15 11:52:31 pequin kernel: mmc0: blksz 32 blocks 2 flags 00000100 tsac 1000 ms nsac 0 Nov 15 11:52:31 pequin kernel: sdhci [sdhci_irq()]: *** sdhci:slot0 got interrupt: 0x00000001 Nov 15 11:52:31 pequin kernel: sdhci [sdhci_irq()]: *** sdhci:slot0 got interrupt: 0x00000002 Nov 15 11:52:31 pequin kernel: mmc0: req done (CMD53): 0: 00002000 00000000 00000000 00000000 Nov 15 11:52:31 pequin kernel: mmc0: 64 bytes transferred: 0 Nov 15 11:52:31 pequin kernel: mmc0: starting CMD52 arg 10002000 flags 00000195 Nov 15 11:52:31 pequin kernel: sdhci [sdhci_irq()]: *** sdhci:slot0 got interrupt: 0x00000001 Nov 15 11:52:31 pequin kernel: mmc0: req done (CMD52): 0: 00001000 00000000 00000000 00000000 Nov 15 11:52:31 pequin kernel: mmc0: starting CMD52 arg 10002200 flags 00000195 Nov 15 11:52:31 pequin kernel: sdhci [sdhci_irq()]: *** sdhci:slot0 got interrupt: 0x00000001 Nov 15 11:52:31 pequin kernel: mmc0: req done (CMD52): 0: 00001000 00000000 00000000 00000000 Nov 15 11:52:31 pequin kernel: mmc0: starting CMD52 arg 10002000 flags 00000195 Nov 15 11:52:31 pequin kernel: sdhci [sdhci_irq()]: *** sdhci:slot0 got interrupt: 0x00000001 Nov 15 11:52:31 pequin kernel: mmc0: req done (CMD52): 0: 00001000 00000000 00000000 00000000 Nov 15 11:52:31 pequin kernel: mmc0: starting CMD52 arg 10002200 flags 00000195 This block gets repeated about 200 times: Nov 15 11:52:31 pequin kernel: sdhci [sdhci_irq()]: *** sdhci:slot0 got interrupt: 0x00000001 Nov 15 11:52:31 pequin kernel: mmc0: req done (CMD52): 0: 00001000 00000000 00000000 00000000 Nov 15 11:52:31 pequin kernel: mmc0: starting CMD52 arg 10002000 flags 00000195 Then: Nov 15 11:52:32 pequin kernel: sdhci [sdhci_irq()]: *** sdhci:slot0 got interrupt: 0x00000001 Nov 15 11:52:32 pequin kernel: mmc0: req done (CMD52): 0: 00001000 00000000 00000000 00000000 Nov 15 11:52:32 pequin kernel: mmc0: starting CMD52 arg 80022201 flags 00000195 Nov 15 11:52:32 pequin kernel: sdhci [sdhci_irq()]: *** sdhci:slot0 got interrupt: 0x00000001 Nov 15 11:52:32 pequin kernel: mmc0: req done (CMD52): 0: 00001001 00000000 00000000 00000000 Nov 15 11:52:32 pequin kernel: libertas: failed to load helper firmware Nov 15 11:52:32 pequin kernel: SDIO: Disabling IRQ for mmc0:0001:1...
