Re: [edk2] [PATCH 1/1] MdeModulePkg/Sd: append CMD12 for multiple blocks

2018-05-09 Thread Haojian Zhuang 
Hi Hao,

OK. I tried to enable auto stop command in Designware MMC driver. So this
patch could be ignored.

Thanks
Haojian

Re: [edk2] [PATCH 1/1] MdeModulePkg/Sd: append CMD12 for multiple blocks

2018-05-02 Thread Wu, Hao A 
Hi Haojian,

Sorry for the delayed response.

As far as I know, we enabled the auto CMD12 feature within:
SdMmcExecTrb(), MdeModulePkg\Bus\Pci\SdMmcPciHcDxe\SdMmcPciHci.c

//
// Only SD memory card needs to use AUTO CMD12 feature.
//
if (Private->Slot[Trb->Slot].CardType == SdCardType) {
  if (BlkCount > 1) {
TransMode |= BIT2;
  }
}

So I think the explicitly sending CMD12 in SdRwMultiBlocks() is not needed.

Have you met problems when using SdRwMultiBlocks()? Could you help to
provide detailed device information when you meet the problem?

Thanks in advance.

Best Regards,
Hao Wu

Send CMD12 to stop transimission for accessing multiple blocks. It's
required by SD Card protocol.
