Hi, for an application I need 14 PRU pins (OUT) for control 7 stepper axis. I tested all pins and all works except P8_45 (0xA0). Is this a known issue?
In the attachments there are the files I tried and checked the outputs with an oscilloscope. For Pin P8_45 I get an output (frequency ~ 100kHz) as soon as the hal_pru_generic driver is loaded (even there should no output). What I did? 1. flash the current machinekit image to BBB (Rev C) (uname -a Linux beaglebone 4.19.106-bone-rt-r49 #1stretch PREEMPT RT Wed Mar 11 10:50:28 UTC 2020 armv7l GNU/Linux) i did it with version *bone-debian-8.7-machinekit-armhf-2017-02-12-4gb.img.xz as well, no luck :(* 2. change uEnv.txt settings: #disable_uboot_overlay_emmc=1 disable_uboot_overlay_video=1 disable_uboot_overlay_audio=1 disable_uboot_overlay_wireless=1 disable_uboot_overlay_adc=1 enable_uboot_cape_universal=1 3. pinmux the pins with config-pin -f pinout.bbio (the file in the attachment) 4. start the application with ./run.py (file in the attachment) 5. check the output of the current pin 5.1 (setp [PRUCONF](DRIVER).pwmgen.00.out.00.pin 160) 5.2. switch setp [PRUCONF](DRIVER).pwmgen.00.out.00.enable 1 to 0 -> no change of the output (the issue) 6. do step 5 for all other PRU1 pins (all works except pin P8_45 (0xA0) Is this a known issue for Pin P8_45? Can someone help me to fix this issue? For example test the attached files to reproduce the issue?!
