So friction is bound to appear when we try to have a generic driver that supports all of these different revisions. So that means there's two options for you right now; experiment wildly and hope you get lucky and find how to avoid whatever bug your particular chip has, or try to get information from Marvell or Raon about how to interface with the chip.

I finally got these firmware files from the manufacturer; still, with 2.6.24-rc6 and the new firmware files, the same errors occur. >> Nov 13 14:40:09 pequin kernel: mmc0: starting CMD53 arg 9a02 flags >> 01b5 >> Nov 13 14:40:09 pequin kernel: mmc0: blksz 32 blocks 2 flags 0100 >> tsac 1000 ms nsac 0 >> Nov 13 14:40:09 pequin kernel: sdhci [sdhci_irq()]: *** sdhci:slot0 got >> interrupt: 0x0001 >> Nov 13 14:40:11 pequin kernel: sdhci [sdhci_irq()]: *** sdhci:slot0 got >> interrupt: 0x00108000 >> Nov 13 14:40:11 pequin kernel: mmc0: req done (CMD53): 0: 2000 >> >> Nov 13 14:40:11 pequin kernel: mmc0: 32 bytes transferred: -110 > > Your problem is here.

Any other sage advice? I feel like the device is really close to working, but I just can't get it there!

I'd guess it is waiting for the firmware to boot, bu you should be getting the debug string "waiting for helper to boot..." in that case. Have you tried with the firmware that's supposed to be used with this board?

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).

Still, my understanding is that the device won't boot the helper firmware until it is entirely loaded, so that shouldn't be the problem. > Nov 13 14:40:09 pequin kernel: mmc0: starting CMD53 arg 9a02 flags > 01b5 > Nov 13 14:40:09 pequin kernel: mmc0: blksz 32 blocks 2 flags 0100 > tsac 1000 ms nsac 0 > Nov 13 14:40:09 pequin kernel: sdhci [sdhci_irq()]: *** sdhci:slot0 got > interrupt: 0x0001 > Nov 13 14:40:11 pequin kernel: sdhci [sdhci_irq()]: *** sdhci:slot0 got > interrupt: 0x00108000 > Nov 13 14:40:11 pequin kernel: mmc0: req done (CMD53): 0: 2000 > > Nov 13 14:40:11 pequin kernel: mmc0: 32 bytes transferred: -110 Your problem is here. 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.
