cmd:GPIO:TI: 'gpio' command Failure Error on Beaglebone Black
Hi,
Error output "*Command 'gpio' failed: Error -19*" is occurring with "*gpio status -a*" command on Beaglebone Black.
The "gpio" command is proper till "U-Boot 2021.04-rc2". Error message is noticed from subsequent releases on-wards.
Problem is noticed on u-boot versions from *U-Boot 2021.04-rc3 to U-Boot 2021.07-rc1* The same command is OK on "sandbox" and "rpi 0 wireless" .
Not sure if the maintenance of code for old boards such as Beaglebone Black is still actively persuaded.Trying to report the observations

Error -19 is ENODEV. Can you check if you have gpio devices being probed?
The "gpio" command is proper till "U-Boot 2021.04-rc2". Error message is noticed from subsequent releases on-wards.
Any chance you were able to bisect to the culprit commit? which defconfig are you using?
Thanks and regards, Lokesh

Hi Lokesh,
Error -19 is ENODEV. Can you check if you have gpio devices being probed?
The device is not being probed.Output of "dm tree" is captured in log_uboot-2021.07-rc1.txt
Where as in uboot-2021.04-rc2.txt,the gpio is probed. The output of "dm tree" is in log_uboot-2021.04-rc2.txt
The "gpio" command is proper till "U-Boot 2021.04-rc2". Error message is noticed from subsequent releases on-wards.
Any chance you were able to bisect to the culprit commit?
No
which defconfig are you using?
We have been using "*am335x_evm_defconfig*"
