HI Mark,
When I started getting boards, I had no idea what system was running in RAM right now. Then I burned the Linux kernel in, but I found that the config-pin tool output information is Beaglebone's information. I'm wondering if I didn't do a good job on the device configuration of BeagleBoard-x15. Best regards, GD 发件人: [email protected] <[email protected]> 代表 Mark A.

Have you seen the PRU Cookbook <https://github.com/MarkAYoder/PRUCookbook> ? It has lots of examples that could help. --Mark On Thursday, February 4, 2021 at 7:56:42 AM UTC-5 [email protected] <mailto:[email protected]> wrote: Hi, I'm a beginner in BeagleBoard-X15. I'm using the beagleboard PRU and i want to debug the PRU gpio which using the CCS and the JTAG. I learned that PRU can directly control GPIO through __R30. I found out from the schematic diagram that the pin GPIO3_7 of P19 on Beagleboard-X15 is PR1_PRU0_GPO0. I want to output Toggle level directly through __R30 and then observe it through oscilloscope but it is doesn't work.I don't know what to do next.
