- AB 02:39 PM Software Development: RE: Pinmux changes back on its own
- Hi Jonathan, thanks for looking into this. The L138 technical reference manual does show many of the SYSCFG registers being modifiable only in a privileged mode, including PINMUX registers. I tried reading and writing to PRU internal gen...
- JC 01:50 PM Software Development: RE: Pinmux changes back on its own
- Found this post for the 335x which mentions that the pinmux registers are protected. Its likely this is also true for the L138.

Thanks Jonathan.

- Hector,
To determine the model of a specific module please refer to the label that is located on the bottom side of the module.
For example you would see the 1810-FG-225-RC which would mean that the module is an AM1810 processor. ... - JC 01:14 PM PCB Development: RE: Questions about my product version

I requested for a MitySOM-1810F + PROFIBUS-development kit from Avnet, and I got kind of confused with the product I received

Your using a newer toolchain than your filesystem. See this forum post: https://support.criticallink.com/redmine/projects/arm9-platforms/activity?from=2014-07-30 - HB 04:39 PM Software Development: RE: Problems with the first time configuration

- JC 10:21 AM Software Development: RE: Pinmux changes back on its own
- Do you have the same problem using the devmem utilty? It also uses the /dev/mem interface. If it works perhaps you can use strace to see what its doing differently.

- JC 09:26 AM Software Development: RE: Pinmux changes back on its own
- Strange, the only time the pinmux should get modified is during u-boot initialization and during kernel boot. Otherwise there isn't anything in linux that should be modifying the pinmux. Unless you need to dynamically change the pinmux...
