Dear all,

 

Hello. I have a question about selection between two possible sources for SDMA_EVENT in i.MX6DQ.

BSP: L3.0.35_4.1.0

 

Refer to "IOMUXC_GPR0 field descriptions" in MCIMX6DQRMM(Rev.2).

DMAREQ_MUX_SEL0 bit of register IOMUXC_GPR0, let us to Selects between two possible sources for SDMA_EVENT[2]:

0 ipu1.ipu_sdma_event  (we think it is related with ipu1)

1 hdmi_tx.hdmi_tx_ophydtb[0] (we think it is related with hdmi tx audio)

 

[Question]

Is it OK to use both ipu1 and hdmi tx audio?

If it is not OK and we want to use both ipu1 and hdmi tx audio at the same time, could you help us to provide the method?

 

Best Regards,

Keita
