CSI/SCI/DMA config

[mynampatikuldee]

Hello,

I am trying to configure and run CSI mode ( SPI/DSI ) & SCI/DMA for MPC5777. I am looking for examples and application notes from NXP. But could not find from NXP site. Can anyone please provide any links or docs?

Thanks,

KK

Hello,

I am sorry. I will rephrase the question. I have already configured SIU_ETPUA, SIU_ETPUB and SIU_EMIOSA/B as desired

in serialized output selection register.

Ex:

ETPUB16, I can see appropriate bit toggling in eTPUB16 channel as well as in DSPIC_SDR0 register.  With appropriate DSCR0, DSCR1 register settings. I expect data frames at output. But unable to see the output.

Are there any other setting's in SIU apart from above mentioned.

Thanks,

KK

Hello,

Thanks alot. That was quite helpful. I was able to successfully configure DSIPC in CSI mode, DSCR1, DSCR2 to desired and able to see SDR0 register bit toggling when I enable (eTPUB9) channel for DSPI serialization. But unable to see output. Are there any registers in SIU to be configured?

Thanks,

KK

Pay attention to following register group:

I could recommend following appnote, it describes old module version that is however backward compatible, but I think it could helpful anyway:

Regrading SCI/DMA, I am attaching simple example code. The rest of the files for this example you may use from following:
