    RE: Compiler/PRU-SWPKG: Application-PRU Support for GNU G++

    Hello Nick, Sorry for the confusion. I was confused with the difference between the PRU and the IPU subsystem, without recognizing that the PRU is a Risc-32-bit versus and Arm M4. Closing the issue as it is arguably a non-issue.

    RE: Linux/PRU-SWPKG: PRU PWM/RPMsg control GPIO

    Hi Nick, Thank you for your reply, For testing, I am trying to have PWM signals working on LEDs. I am more interested in generating my PWM signal manually from the PRU. Do you have some application note about this use case ? Thanks

    RE: Compiler/PRU-SWPKG: clpru behaves differently in docker image vs ubuntu desktop; fails with "exec() error spawning acpiapru: No such file or directory"

    We do not test clpru (or any other TI compiler) under Docker. Whether running under Linux or Docker, the shell clpru invokes the sub-process acpiapru with the system call execvp. It has worked this way for a long time. Therefore, it is likely the problem...

    RE: Linux/PRU-SWPKG: PRU program load

    Will read further about the Processor SDK and the Remoteproc framework, but as far as i know, the Processor SDK does not support non-Ubuntu Linux distros, correct? Thanks for the quick answer.

    RE: PRU-SWPKG: Sharing variables across PRUs

    Puneeth, Please see the memory map for the PRU subsystems in the AM437x TRM ( http://www.ti.com/lit/pdf/spruhl7 ) in Table 30-5 in section 30.3.1.2. You'll see that PRU-ICSS0's PRU0 accesses its own local memory (PRU0 DRAM) at address 0x0000...

    RE: PRU-SWPKG: Sharing data between ARM and PRU

    Puneeth, Please try adding pinctrl-names = "default"; to your pru0_1 node (shown below). I just copied and pasted your pru0_1 node into my DT and without that line my devmem2 was showing mux mode 7 (like yours). When I added that line, devmem2...

    RE: PRU-SWPKG: PRU-ICSS UART pins

    Once you find the pins, they will need to be muxed to the proper mux-mode in order to bring out the signals from the PRU core to the SoC pins. There is a user guide for the PRU Cape for BeagleBone Black. It has a table that details which BBB header pins...

    RE: CCS/PRU-SWPKG: Loading PRU code from Linux

    Puneeth, The latest versions of the TI Provided C compiler for the PRU can be found here: http://software-dl.ti.com/codegen/non-esd/downloads/download.htm#PRU . There is no need to download CCS to get it or use the old beta link that you've posted...

    RE: Linux/PRU-SWPKG: PRU PWM issue

    Puneeth, The eQEP pins belong to the eQEP module that is outside of the PRU Subsystem. The PRU code that is controlling the eQEP peripheral in the example (in prupid_fw_1/PRU_IO_1.c) is actually just reading from and writing to the eQEP registers using...
