Original question:

AM625: How to set a specific GPIO to High in uboot

AM625: How to enable gpio command in u-boot

Také
Prodigy 30 points

Part Number: AM625

I am using AM62 uboot and would like to use the gpio command for debugging work.

At the moment, the uboot built with reference to the following is working by writing to eMMC via DFU, but the gpio command is not available.

software-dl.ti.com/.../UG-General-Info.html


Therefore, I opened menucofig with the following command, opened configs/am62x_evm_a53_defconfig from load, changed CONFIG_CMD_GPIO to y and built again.

sudo make menuconfig ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabihf-

Then,  I have not found any errors in include/common.h:16's include/ config.h:4:10 at include/common.h:16, but it failed with No such file or directory.

I do not understand the cause of this. Do I need to bring anything additional?
By the way, if I edit am62x_evm_a53_defconfig directly and set CONFIG_CMD_GPIO=y, it does not work correctly, but the build succeeds and I can execute the command.

=> gpio set 409
i2c_write: error waiting for data ACK (status=0x116)

    Hello,

    Can you provide the full log when you try to compile after using menuconfig?

    Can you also provide the output of 'gpio status' at the U-Boot prompt?

    Best Regards,

    Anshu

    Hello,

    Our U-Boot expert is out of office for the next week, so I'll try to provide assistance where I can.

    Can you try this command:

    export UBOOT_DIR=<SDK install path>/board-support/u-boot-<version>

make ARCH=arm CROSS_COMPILE=<Full Path to the CC>/arm-gnu-toolchain-11.3.rel1-x86_64-aarch64-none-linux-gnu/bin/aarch64-none-linux-gnu- am62x_evm_a53_defconfig O=$UBOOT_DIR/out/a53

    For future readers, CONFIG_CMD_GPIO is set to yes by default in SDK 9.0+.

    Best Regards,

    Anshu

    Hello,

    Would that be equivalent to what is described in the aforementioned link?
    The command at make after menuconfig already uses it.

    Best Regards,

    Hello,

    Yes its similar. I was able to build it on my end that way, so I ask you to do the same in case it helped.

    Thanks,

    Hello, 

    I tried again using the command you told me to use, but I got the same error as last time, except the output hierarchy was different.
    I am passing the full path to the compiler.

    Best regards.

    Hello,

    After discussion internally, the top level makefile should also work as a way to compile: https://software-dl.ti.com/processor-sdk-linux/esd/AM62X/09_02_01_10/exports/docs/linux/Overview/Top_Level_Makefile.html

    Try using the top-level makefile to see if the error persists.

    Best Regards,

    Anshu
