Re: [PATCH] mmc: dw_mmc: enable controller interrupt before calling mmc_start_host

Hi, I looked at the clock thing, and it appears that there's an extra divide by two in hardware (the TRM says "Clock division is 2*n"), so those numbers do appear to be correct. >From some experimentation the other day, it appeared to be a race condition which is affected by the position of the d

Re: [PATCH] mmc: dw_mmc: enable controller interrupt before calling mmc_start_host

Hi All, Well, i didn't find the James's error message. But i confused about the clock value. Bus speed : 9984Hz request : 20Hz Div : 250 If bus_speed is divided with div, then actual value should be 399360Hz. But this log is produced 199680Hz. What's wrong? I think this message can be

Re: [PATCH] mmc: dw_mmc: enable controller interrupt before calling mmc_start_host

Dear James, Its not sufficient.In my case, sdio_reset command was submitted to dw_mmc controller before interrupts are enabled. By looking at your log,it seems something wrong with frequency set by your U-boot. Best Regards Yuvaraj On Mon, Nov 19, 2012 at 6:50 PM, James Hogan wrote: > On 19/11/1

[PATCH] mmc: dw_mmc: enable controller interrupt before calling mmc_start_host

As mmc_start_host is getting called before enabling the dw_mmc controller interrupt, there is a problem of missing the SDMMC_INT_CMD_DONE for the very first command sent by the sdio_reset. This problem occurs only when we disable MMC debugging i.e, MMC_DEBUG [=n]. Hence this patch enables the dw_mm
