Hi all,
I'm using an XMC4800 relax kit as a "midware" which on one hand reads from a sensor via SPI, on the other hand sends out the data through EtherCAT.
Problem here is, with EtherCAT taking up a lot of pins, theoretically I can only use the following two SPI modules:
Attachment 2629
The rest are either used by EtherCAT or not populated.
While P3.7-P3.9 worked perfectly, P0.13 did not seem to produce any clock signal when probed in oscilloscope. It's worth noting that I had to probe P0.13 through Arduino pins since it's not populated in X1 and X2.
From XMC4700_XMC4800_Relax_Kit_Series_UM_v01_00_EN.pdf page 12, (shown below) I saw that P0.13 shared the same Arduino pin with P14.5, and is marked with I2C_SCL. So is it that this pin can only be used as an I2C SCL, or some other config is needed to prob P0.13 on this pin?

Any help would be appreciated!
