Unable to Run PWMSS0, PWMSS1, and PWMSS2 from PRU on Beagle Bone Black.

Other Parts Discussed in Thread: SYSCONFIG, TPS65217

This is an issue I reported back in December 2015, still no answer. I am using ti-processor-sdk-linux-am335x-evm-02.00.01.07.

I wrote code to dump registers from the PRU to Linux user space. The register are being set correctly...

Except for the following

pwmss_ctrl Register (offset = 664h) [reset = 0h] i try to write 0x7, to enable clocks, and it stays 0x0.

I have tried to set the SYSCONFIG Register (offset = 4h) [reset = 28h] in all three PWM Sub-Systems. The TRM says the reset should be 0x28. That is not true, On my BBB it is always 0x8.

What do I need to enable in order to get the PWM Sub-Systems out of STANDBYMODE?

I also wrote code to enable the PWM Sub-Systems from the Linux user space. I got the exact same results.

Here is a dump of my initialization:

Hi,

Can you post the absolute addresses of all these registers, as you have defined them?

To enable the PWMSS subsystems you first need to enable the clocks (section 15.1.2.3 of the AM335X TRM Rev. M). This wiki page describes the sequence necessary to start the eHRPWM submodule. It's for Starterware but you can use it as a guideline.

What wiki page?

section 15.1.2.3 describes the CLKCONFIG register.
That register is being set.

This is what I wrote:
PWMSS0 CLKCONFIG 0x00000111
PWMSS1 CLKCONFIG 0x00000111
PWMSS2 CLKCONFIG 0x00000111

This is what I read back:
PWMSS0 CLKCONFIG 0x00000111
PWMSS1 CLKCONFIG 0x00000111
PWMSS2 CLKCONFIG 0x00000111

Is 15.1.2.4 the CLOCK status?
CLKSTATUS Register (offset = Ch) [reset = 0h]
CLKSTATUS is shown in Figure 15-6 and described in Table 15-8.
The clock status register is used in the PWMSS submodule for clkstop ack and clk_en ack status.

This is what I read from CLKSTATUS:
PWMSS0 CLKSTATUS 0x00000111
PWMSS1 CLKSTATUS 0x00000111
PWMSS2 CLKSTATUS 0x00000111

This indicates the clocks are running, correct?

Yes, this is correct. Sorry about the link in my previous post, here it is again: processors.wiki.ti.com/.../StarterWare_EHRPWM

The functions referenced in the document do not exist in StarterWare.

I am beginning to highly suspect the pin-mux parser in the TI SDK.

I am not able to even get PWMSS2 eCAP2 or PWMSS0 eCAP0 running.

On the BBB PWMSS0 eCAP0 shares the same pin with pru1 eCAP.

pru1 eCAP works fine.

Michael,

Can you confirm that you are writing a 0x2 into bits 1:0 of the CM_PER_EPWMSSn_CLKCTRL registers before attempting to use the peripherals? I see where you create the definitions for the addresses and the definition of the correct value, but I can't see if you are writing it anywhere.

Something like this:
#define CM_PER_EPWMSS1 (*((volatile unsigned int *)0x44E000CC))
while (!(CM_PER_EPWMSS1 & 0x2))
CM_PER_EPWMSS1 |= 0x2;

Yes, all clock control registers are set correctly, I read them all back to verify.

all clocks are running, all registers are set correctly. I just do not get pwm output on any configured pins.

This appears to me the SDK is broken, specifically the device tree parser driver. I do not use device tree overlays,

I have tried the ehrpwm and ecap on all three Sub-system Modules (PWWSS0, PWMSS1, PWMSS2), neither module will output pwm on the configured pins.

regards,

Mike Brainerd

Mike,

Seems like we might be running into a pin mux issue. After your board boots can you put the contents of dmesg into a text file and post it here as an attachment.

root@am335x-evm:~#dmesg > dmesg.txt

I'm assuming that we'll get some errors on some 'pinctrl' lines.

I don't see any pin mux conflicts occurring in dmesg. Can you post your dts file where you are trying to configure your pin muxing?

Nothing jumps out at me in the dts file. Have you tried turning off the kernel modules that are enabled by default in your .config file? They might be trying to control the same registers that your PRU firmware is trying to control. Below are the default .config settings.

CONFIG_PWM_TIPWMSS=y
CONFIG_PWM_TIECAP=y
CONFIG_PWM_TIEHRPWM=y

I just did a grep for:

CONFIG_PWM_TIPWMSS=y
CONFIG_PWM_TIECAP=y
CONFIG_PWM_TIEHRPWM=y

They are not in my .config file,

They are in arch/arm/configs/tisdk_am335x-evm_defconfig, which is what I started with.

But I turned that off a long time ago from menuconfig panel > Device Drivers > Pulse-width Modulation (PWM) support.

What is the Status of this issue?

How do we escalate this?

I have been struggling with TI support for more than Three months.
