PROCESSOR-SDK-AM68A: Configuring spidev for the 40 pin header

Hi Faheem,

It should be possible to enable MCU_SPI1 since MCU_SPI1 is connected to expansion header. If you already have SPI set up, you would need to pinmux MCU_SPI1 using sysconfig, and use the new pinmuxed pins in the spi nodes.

Regards,

Takuma

I got the spi node enabled as spidev1. I also want two GPIO pins for an Interrupt signal and a reset signal. But there aren't any gpio nodes in /sys/class

https://software-dl.ti.com/jacinto7/esd/processor-sdk-linux-am68a/09_02_00/exports/edgeai-docs/devices/AM68A/linux/pi_hdr_programming.html?highlight=rpi Have referred this document and followed the steps to enable the GPIO pins. https://github.com/TexasInstruments/ti-gpio-py Sample scripts from here are not able to access GPIO pins.

Hi Faheem,

1. Could you check /run/media/BOOT-mmcblk1p1/uEnv.txt to make sure the overlay is added as documented?

2. Could you share boot logs?

3. Could you share logs from running the sample scripts?

Regards,

Takuma

I have added the overlay as documented 

These are the boot logs

Where <package> is the name printed in the list above

NOTE: If the package is a dependency of another package you
      will be notified of the dependent packages.  You should
      use the --force-removal-of-dependent-packages option to
      also remove the dependent packages as well

Hi Faheem,

I tried installing 9.2 SDK for SK-AM68A and tried setting up the GPIO example and have not had issues. Attaching logs that can be used as reference for the setting up the GPIO library:

I noticed the ti-gpio-py is in the home directory instead of under the /opt/ directory in your log. There is a "install_ti_gpio_libs.sh" script under /opt/edgeai-gst-apps/scripts, but was this script used, or were the libraries installed manually?

Hi Takuma,
I want to check whether this spi node corresponds to MCU SPI1 and is accessible from RPI header. Could you confirm this?

spidev0.0 -> ../../devices/platform/bus@100000/bus@100000:bus@28380000/40310000.spi/spi_master/spi0/spi0.0/spidev/spidev0.0

Hi Faheem,

Yes, 40310000 should correspond to MCU_SPI1

Regards,

Takuma
