GPIO trouble PY6 & PS3

Hi All,

I’m having difficulty getting the following pins working on my TX2.

Ball: A22 - GPIO3_PY.06
Ball: B23 - GPIO3_PS.03

When I export GPIO486 (PY6) and set it to input and read its value it always replies 0 despite the fact that I’m measuring 1.8V on the pin - also forcing the pin to 0V still yields a 0 response.

The AON cluster (I think) has an offset of 256 hence PS.03 should be gpio259 - but exporting this pin and reading it also yields 0 regardless of the physical pin being high or low.

Any suggestions?

DTS as follows:

gpio@2200000 {
compatible = “nvidia,tegra186-gpio”;
reg-names = “security”, “gpio”;
gpio-controller;
gpio-ranges = <0x9d 0x0 0x0 0x90 0x9d 0x90 0x98 0x8 0x9d 0x98 0xb8 0x10 0x9d 0xa8 0xd8 0x18>;

hello LasseRoedtnes,

please refer to GPIO Changes session for an example to check the GPIO number.
you may check kernel initial messages for the GPIO allocation ranges,
for example,

[    0.453162] gpiochip_setup_dev: registered GPIOs 320 to 511 on device: gpiochip0 (tegra-gpio)
[    0.456934] gpiochip_setup_dev: registered GPIOs 256 to 319 on device: gpiochip1 (tegra-gpio-aon)

it looks you’re having correct GPIO numbers according to the calculation formulas for these two pins,
GPIO3_PY.06 = ((20 * 8) + 320) + 6 = 486
GPIO3_PS.03 = (( 0 * 8) + 256) + 3 = 259

could you please have a try with Jetson-GPIO python library to configure GPIO pins.
thanks

Hi Jerry,

I dont see the GPIOs listed in my dmesg output (see below) - any input would be appriciated!

hello LasseRoedtnes,

please note that there’s buffer limitation for the logging, you may reboot the system and check the very beginning parts of kernel logs.
you could also setup serail console for an alternative ways to gather logs.
thanks

As mentioned if i cat the value of the pins it always returns 0 despite me measuring a logic 1 on the physical pin.
I have tried setting the pin to physical logic 0 but that also returns a 0 from the value register.

Hi @JerryChang

There is certainly some odd bug going on here!

If i do this straight after booting:

logmar@logmar-desktop:/usr/local/cameraapp$ cd /sys/class/gpio/
logmar@logmar-desktop:/sys/class/gpio$ echo 486 > export
logmar@logmar-desktop:/sys/class/gpio$ cd gpio486
logmar@logmar-desktop:/sys/class/gpio/gpio486$ cat value
0
logmar@logmar-desktop:/sys/class/gpio/gpio486$ cat direction
in
logmar@logmar-desktop:~$ python3
Python 3.6.9 (default, Oct 8 2020, 12:12:24)
[GCC 8.4.0] on linux
Type “help”, “copyright”, “credits” or “license” for more information.

import gpio
gpio.setup(486, gpio.IN)
gpio.read(486)
1

If I then exit python and read with sysfs again it now returns 1
logmar@logmar-desktop:/sys/class/gpio/gpio486$ cat value
1

How on earth can this happen !!!???

Also if I tie the pin physically low then the status now correctly shows 0 via cat as well and it does go to 1 once I apply 1.8V to the pin.

Thanks
Lasse

Hi @JerryChang

I investigated it further and if I purposefully set a 0 to active_low the pin becomes operational.

If i do this from boot:
root@logmar-desktop:/home/logmar# cd /sys/class/gpio
root@logmar-desktop:/sys/class/gpio# echo 486 > export
root@logmar-desktop:/sys/class/gpio# cd gpio486
root@logmar-desktop:/sys/class/gpio/gpio486# cat value
0
root@logmar-desktop:/sys/class/gpio/gpio486# echo 0 > active_low
root@logmar-desktop:/sys/class/gpio/gpio486# cat value
1

But this should be the default state if nothing else is specified in the DTS so why is this ?

hello LasseRoedtnes,

yes, it’s device tree to include GPIO definitions.
you may disassembler the dtb file into text file for quick checking,
for example,
$ dtc -I dtb -O dts -o output.txt tegra186-quill-p3310-1000-c03-00-base.dtb

please note that,
if there’s pinmux changes, it’ll also have MB1 Configuration Changes that might overwrite the settings.
you should also check mb1-bct configuration files for examination.
i.e. $OUT/Linux_for_Tegra/bootloader/t186ref/BCT/tegra186-mb1-bct-pmic-quill-p3310-1000-a00.cfg

BTW,
please also refer to discussion thread, Topic 144550 for several ways to access/control GPIOs; such as, kernel APIs, python scripts, C++ samples.
thanks

Hi JerryChang

I updated both my DTS and MB1 configuration however the problem persists.

Please investigate this from your side as it must be a bug.

I checked A22/GPIO3_PY.06 on my board and it works properly as an input GPIO, reading both HI/1 and LO/0 when the voltage changes. Double check your PADCTL_UART_GPIO_MDM7 @ 0x0243d090 and make sure it is programmed properly for reading as a GPIO.

Here is mine:

# devmem2 0x0243d090
/dev/mem opened.
Memory mapped at address 0x7f888b2000.
Read at address  0x0243D090 (0x7f888b2090): 0x00000058

Decoded 0x58 value:

ENABLE[6]      = 1 (ENABLE)
TRISTATE[4]    = 1 (TRISTATE)
PULL_DOWN[3:2] = 2 (PULL_UP)
RSVD0[1:0]     = 0

I do not have access to B23/GPIO3_PS.03 on my board, but it appears to work properly as a GPIO input also when I control the pull-up/pull-down on the processor:

/sys/class/gpio# devmem2 0x0c301030
Read at address  0x0C301030 (0x7f8f2a8030): 0x00000059 # PULL-UP is enabled
/sys/class/gpio# echo 259 > export
/sys/class/gpio# cd gpio259/
/sys/class/gpio/gpio259# echo in > direction
/sys/class/gpio/gpio259# cat value 
1
/sys/class/gpio/gpio259# devmem2 0x0c301030 w 0x55
Read at address  0x0C301030 (0x7fa7359030): 0x00000059 # PULL-DOWN is enabled
/sys/class/gpio/gpio259# cat value 
0
/sys/class/gpio/gpio259# devmem2 0x0c301030 w 0x59
Write at address 0x0C301030 (0x7fabe20030): 0x00000059, readback 0x00000059 # PULL-UP is enabled
/sys/class/gpio/gpio259# cat value 
1

Note: the test of B23/GPIO3_PS.03 is not definitive as sometimes the SoM places a buffer on the pin before getting to the SoC and the signal does not get through from the outside to the processor.
