Linux/AM4376: L3 custom error

Conrad Ratschan
Prodigy 140 points
Part Number: AM4376
Other Parts Discussed in Thread: AM4372

Tool/software: Linux

Hello all,

We have a custom board with an AM4376 processor. We are running the Linux kernel from the TI Processor SDK version 4.03.00 with extra patches to remove the RTC in both the source and device tree (as it is disabled on the hardware). When using the pwm-omap-dmtimer driver to enable PWM on timer5, we get the L3 custom error messages listed below after each action (set period, set duty cycle, enable). The driver still works as intended and we are able to get our PWM signal, but we cannot have these error messages appearing.

# echo 25000000 > /sys/class/pwm/pwmchip0/pwm0/period

We have tried solutions from the following threads, but have not resolved the issue:

The last link has the same error coming from the pwm_omap_dmtimer driver and is unresolved.

Are there any other leads we can follow-up on to get these errors fixed?

Thanks,

Conrad

    I was also able to elicit the same behavior on the TI AM4372 Starter Kit with a kernel based off of the 4.14.25 version of the upstream Linux kernel. Trace listed below:

    Able to work around the problem by switching the pwm-omap-dmtimer driver to use the high frequency system clock rather than the 32kHz always on clock. This caused all L3 error messages to disappear
