About MMC_OBI

Where did you see this pin? Are you sure you spelled it correctly? There is no such pin on the AM387X, DM814X processors.

Hi Biser,

                sorry,please refer the DM814X technical reference manual page 1728, can see the attached picture,thanks.

Huang,

Attachment is missing. Are you referring to the latest version of DM814x TRM SPRUGZ8B? In that document there is nothing like mmc_obi.

Hi Renjith ,

                      Yes,the the last version of  DM814x TRM SPRUGZ8B is page 2268 Figure 18-1. MMC/SD/SDIO Overview,

                      update attached file again,thanks.

The pin name is MMC_OBL and not MMC_OBI. That's why the confusion. But looks like this is an internal pin which is grounded, which we might not have to worry. May be this might be the requirement from MMC/SD Controller ip provider. 

Hi Renjith,

                     Sorry,the internal pin which is grounded,do you know the function of this pin(MMC_OBL )?Thank you

I don't know the function of the pin. Are you facing any issue with this? What exactly are you trying with MMC? Mark the post as answered, if you think the query is solved.

Hi Renjith

                          Without any problem, just want to know MMC_OBl function.

Hi Aska,

I really don't know what it is used for. I thought helping you out if you are facing some issue in MMC driver and if you are suspecting this pin.
