Hello,
It seems you’re encountering issues with ECSPI1 and ECSPI2 on your Colibri iMX7 module, where these interfaces are not generating SCLK pulses. Let’s go through some steps to help troubleshoot and resolve the issue:
-
Device Tree Configuration:
- Double-check the pin multiplexing settings in your device tree for ECSPI1 and ECSPI2. Ensure that the pins are correctly configured for SPI functionality and not being used by another peripheral.
- Verify that the
statusproperty for both ECSPI1 and ECSPI2 is set to “okay” in the device tree.
-
Kernel Logs:
- Check the kernel logs (
dmesg) for any errors or warnings related to SPI. This can provide clues if there are issues with the SPI driver or hardware initialization.
- Check the kernel logs (
-
Testing SPI Communication:
- Use user-space tools like
spidev_testto manually test SPI communication. This can help verify if the issue is with the SPI configuration or the specific devices connected.
- Use user-space tools like
-
Driver and Overlay Configuration:
- Ensure that there are no conflicting device tree overlays or kernel modules that might be affecting SPI operation.
By following these steps, you should be able to identify and resolve the issue with ECSPI1 and ECSPI2. If the problem persists, consider reviewing your software configuration to ensure all settings align with your intended setup.
