MPC56xx DSPI: PIN 213

[robertwynn]

Hello,

I am using Codewarrior 11.1 and have a SPC5634MMLU80 XRJ2001 1M35Y (176pin) processor.

I have been using DSPI_B (DSPI_B_SOUT on GPIO[104]) and the configuration works fine.

I have a new board with DSPI_B_SOUT on GPIO[213] I can not get it to work. GPIO[213] seems to mirror the SCK signal not the SOUT signal.

SIU .PCR[213].B.PA = 2; // does not work (this has been checked on two boards)

SIU .PCR[104].B.PA = 1; // does work

Is there something that I have to change because [213] has WKPCFG and NMI functionallity?

Thanks

Thanks David. I will rewire the board.

Hi, I have seen this in the past and I was answering:

"I can confirm observed behavior. I have found that SIU_IREER[NMIRE] SIU_IREER[SWTRE] act the same way and blocks PCR setting."

I checked previous communication and this has been reported and doc ticket probably has been raised. But as it is currently old device, no new RM has been issued.

One yet note that EVB board has jumper J9 choosing external pull-up or pull-down what can influence it as well.
