Pin32 of Orin Nano still does't work as PWM after reinstall new GPIO @2.1.3

ObamaIII opened this issue a year ago · 17 comments

Hi Guys,
Pin32 of Orin Nano still does't work as PWM after reinstall new GPIO @2.1.3. But Pin15 and Pin33 can work well as PWM.

I use gpio-io.py to set Pin15,32,33 as PWM and reinstall new version 2.1.3 GPIO but Pin32 still doesn't work as PWM.
So I think that gpio_pin_data.py doesn't define JETSON_ORIN_NANO_PIN_DEFS. It is the reason.
Looking forward to resolving the BUG.

Thanks a ton

Answer 1 · 2023-08-31T20:16:39.000Z

what kernel version and what BSP version are you using?

Answer 2 · 2023-09-01T04:58:46.000Z

Can you get GPIO.VERSION also

Answer 3 · 2023-09-01T05:50:38.000Z

Hi, Linh,
kernel version=Linux Kernel 5.10.104
BSP version = NVIDIA Jetson Linux 35.3.1
GPIO.VERSION = 2.1.3
JetPack 5.1.1

Thank you very much for your great help.

Can you get GPIO.JETSON_INFO also

Answer 6 · 2023-09-07T16:33:20.000Z

Also can you show me

ls /sys/devices
ls/sys/devices/playform

Answer 7 · 2023-09-07T16:41:14.000Z

Also can you show me

ls /sys/devices ls/sys/devices/playform
GPIO.JETSON_INFO

ls /sys/devices
ls /sys/devices/playform

Answer 8 · 2023-09-07T18:28:21.000Z

oh I mean

ls /sys/devices/platform

Answer 9 · 2023-09-07T18:40:04.000Z

3280000.pwm
32a0000.pwm
32c0000.pwm
nvidia@tegra-ubuntu:~/mypro$ ls /sys/devices/platform：

In lib/python/Jetson/GPIO/gpio_pin_data.py:
(85, 'PN.01', "tegra234-gpio", 15, 22, 'GPIO12', 'GP88_PWM1', '3280000.pwm', 0),
(41, 'PG.06', "tegra234-gpio", 32, 12, 'GPIO07', 'GP113_PWM7', '32e0000.pwm', 0),
(43, 'PH.00', "tegra234-gpio", 33, 13, 'GPIO13', 'GP115', '32c0000.pwm', 0),

Looks like .pwm is same in platform and gpio_pin_data.py, but JETSON_ORIN_NX_PIN_DEFS is NOT compats_jetson_orins_nano = (
seems like JETSON_ORIN_NANO_PIN_DEFS is NOT Defined in /gpio_pin_data.py.

(41, 'PG.06', "tegra234-gpio", 32, 12, 'GPIO07', 'GP113_PWM7', '32e0000.pwm', 0),

need to change '32e0000.pwm' into '32a0000.pwm' IN (41, 'PG.06', "tegra234-gpio", 32, 12, 'GPIO07', 'GP113_PWM7', '32e0000.pwm', 0), right?

Answer 14 · 2023-09-07T20:01:13.000Z

32a0000.pwm is the fan. I read the release note again and found out that pin32 as PWM is only supported on BSP 35.4.1

Answer 15 · 2023-09-07T20:46:47.000Z

So probably need to update your BSP to 35.4.1 or avoid using pin 32 as pwm

Hi,
Thank you very much for your great help.
I will try to update my BSP to 35.4.1. Do I copy only 32e0000.pwm from BSP 35.4.1 to my /sys/devices/platform? because there is no 32e0000.pwm in the directory.
