LP-AM243: 2 HDSL connections on PRU1/0 for Motor Drive

Wolfgang Steinwender

Part Number: LP-AM243


I have one HDSL connection with ICSS0 PRU1 using the first instance of the HDSL Modules.

Here I'm using CH0 (Pin T4,J2,M2) .It is working with my target.

For the second I use ICSS0 PRU0 CH0 (Pins N1,J4,G1). These Pins are free available on the strip, so i can connect them to my target.

This is not working. I suppose that the PRU internal MUX setting is not Ok. The programs running on the PRU1 and PRU0 are the

same..

Unfortunately the PRU documentations SpuJ61 seems not to be updated, neither I can find any TRM regarding DSL/Endat/Ethercat etc.

There are only the examples which are not enough, if the configuration does not match the needs.

Can someone help me ?

    Hi Wolfgang,

    By default, the HDSL PRU-ICSSG FW is running on the PRU_ICSSG0_PRU1. Of course, you can change it to the PRU_ICSSG0_PRU0, but you have to make the change in the syscfg, like the attached screen capture:

    Best regards,
