unable to enable gpio pins when uboot-overlays is disabled in uEnv.txt file on debian 8.7

[jithu...@gmail.com]

Hi everyone,

I am not able to enable any GPIO pins and then toggle them using (for eg:  config-pin P8.7 gpio) command. 

debian@beaglebone:~$ config-pin P8.7 gpio

P8_07 pinmux file not found!

Pin has no cape: P8_07

Actually  in uEnv.txt i have disabled uboot-overlays because when i enable it i am not able to play audio.when i disable it i am able to play audio.

###Master Enable

#enable_uboot_overlays=1

###Cape Universal Enable

enable_uboot_cape_universal=1

(i enabled cape-universal also but as uboot-overlay is disabled cape-universal is also not working i guess)  

cape_enable=bone_capemgr.enable_partno=BB-UART2,BB-UART4,BB-BONE-AUDI-02

(this is to enable audio)

So i just want to know is there any other way to enable GPIO other than uboot-overlay(cape-universal) as i cant compromise on audio. Audio is must for my project. I have tried multiple ways for audio.only this method worked. So i want alternative way for enabling GPIO.

Please help ASAP.

Thanks in advance.

This was fixed within the last couple of weeks..

Run

sudo /opt/scripts/tools/version.sh

So we can find out what your running.

Regards,

Thanks in advance.

Hi Robert,

Thanks alot for replying. Ok but when i searched i couldnt find a solution. It will be really helpful if u will look into this. Here is the version.sh log which u asked for.

debian@beaglebone:~$ sudo /opt/scripts/tools/version.sh

[sudo] password for debian:

git:/opt/scripts/:[4dd50b306e4eb31a05bb72a9573febc3695f1f05]

eeprom:[A335BNLT00C04717BBBK0E43]

dogtag:[BeagleBoard.org Debian Image 2017-03-19]

bootloader:[/dev/mmcblk0]:[U-Boot 2017.03-00002-gd12b1519b4]

kernel:[4.4.54-ti-r93]

nodejs:[v6.14.3]

device-tree-override:[dtb=ibot_controls.dtb]

The dtb file is the one which i compiled for some extra features.

Thanks,

Jithu

too old, you'd need 2018.03

> kernel:[4.4.54-ti-r93]

wrong branch, you'll need v4.14.x-ti (4.14.65-ti-r72)

> nodejs:[v6.14.3]
> device-tree-override:[dtb=ibot_controls.dtb]

this disables the config-pin path in v4.14.x-ti.. (4.14.65-ti-r72)

This would get you that:

```
debian@test-bbb-2:~$ cd /opt/scripts/tools/
debian@test-bbb-2:/opt/scripts/tools$ git pull
Already up-to-date.
debian@test-bbb-2:/opt/scripts/tools$ sudo ./update_kernel.sh
--ti-channel --lts-4_14
debian@test-bbb-2:/opt/scripts/tools$ sudo ./developers/update_bootloader.sh
debian@test-bbb-2:/opt/scripts/tools$ sudo apt install --only-upgrade
bb-cape-overlays
```

Just remember, to disable dtb=ibot_controls.dtb in /boot/uEnv.txt

and have:

enable_uboot_overlays=1
enable_uboot_cape_universal=1

enabled...
