PINMUX
Are the latest versions being build in the rcn-ee testing images?
Yes, that’s close enough. There are more frequent builds as well, but I’m wondering if there is synchronization going on with RobertCNelson (rcn-ee).

Week 10
BB-Config Features Latest Updates:
Features | Video | Status | PRs
- ADC Graph
- (Demo) [Done] {Passes}
- DAC(PWM)
- (None) [Done] {waiting}
- uEnv config
- (Demo) [Done] {waiting}
- PinMux
- (Demo) [Done] {waiting}
- NetworkManager
- (None) [Testing] {No}
- File Sharing
- (None) [Developing] {No}
Obstacles
- BB-Blue NetworkManager not support
- I still not sure how to implement file sharing in NFS. I still research on it, highly possible I will implement file sharing on ssh.
Next Week
- Gather data for /sys/ method
- Writing code with libgpiod
Week 11
Achivement
BB-Config
ADC Graph
DAC(PWM)
uEnv config
Enable/Disable startup service
PinMux
NetworkManager (going through dbus documentation)
File Sharing (Implement requires recompile the kernel, so dropped it out)
GPIO - Benchmark
Code:
Shell (sys)
C++ (sys)
C (Memory Mapping)
C (libgpiod)
Python
BoneScrtipt
PRUs
LKM
Data:
Beaglebone Black (gpio write)
Next Week
- work on overlay-cap (bb-config)
- GPIO Code for LKM
- Test gpio for pocket, AI, AI-64.

btw, in the ‘5.10.x-ti’ series, i’ve been playing around with and have enabled ksmbd:
might be a useful option for file sharing.

The PRU values are spot on.
The C memory map versions are slow. They should be just under 3MHz. The limitation is likely the wait on the internal bus for the write to post. If you could somehow disable the “strongly ordered” constraint on the MMAP, you could probably match the 12.5MHz of the PRU.

The Linux Kernel Module should also be 12.5MHz. See:
