SD1_DATA mux mode

[endl]

Hello

I'm trying to use the "iMX 6Series Plarform SDK v1.1.0" for my demo board with iMX6DL processor.

There is a function  void hdmi_tx_phydtb_pgm_iomux(void)  from the file /board/common/board_hdmi.c.

This function configures mux mode to ALT6 for SD1_DATA0 pad and SD1_DATA1 pad ( // for hdmi_tx instance OPHYDTB[0]/OPHYDTB[1] port ??? ).

I have not found this mux mode for SD1_DATA pad from Reference Manual

Field	Description
2–0 MUX_MODE	MUX Mode Select Field. Select 1 of 3 iomux modes to be used for pad: SD1_DAT0. 000 ALT0 — Select signal SD1_DATA0. 011 ALT3 — Select signal GPT_CAPTURE1. 101 ALT5 — Select signal GPIO1_IO16.

What makes this setting ? And what is the OPHYDTB ? Thank you

Hi Vadim

these signals are hdmi test signals, mux mode ALT6 was removed from latest RM,

described in sect.35.7.31 Digital Transmission Mode (HDMI_PHY_DIGTXMODE) IMX6SDLRM

Best regards

igor
