Based on the context provided, I don’t have specific information about the Verdin AM62’s SPI performance issues or detailed troubleshooting steps for the described problem. However, I can offer some general suggestions that might help address the SPI performance delay:

1. Check CPU Load and Interrupt Handling: High CPU load or inefficient interrupt handling can cause delays. Ensure that the CPU is not overloaded and that the interrupt service routines (ISRs) are optimized for minimal execution time.

2. Real-Time Configuration: If your application requires strict timing, consider using a real-time kernel or configuring the system for real-time performance to reduce latency.

3. SPI Driver and Configuration: Verify that the SPI driver is configured correctly. Check for any known issues or updates related to the SPI driver for the Verdin AM62.

4. DMA Configuration: Since you have already tried enabling DMA, ensure that the DMA configuration is optimal. Sometimes, tweaking DMA settings can help improve performance.

5. Thermal and Power Management: Ensure that the system is not throttling due to thermal or power management settings, which can introduce delays.

6. Kernel and System Logs: Check kernel and system logs for any warnings or errors that might indicate underlying issues affecting SPI performance.

7. Consult TI Resources: Since the Verdin AM62 is based on a TI processor, consulting TI’s resources and forums for similar issues might provide additional insights or solutions.

If these suggestions do not resolve the issue, it may be beneficial to reach out to Toradex support or the community for more specific guidance related to the Verdin AM62 module.

SPI MISO on Verdin Eval Board

Hello, I have a Verdin Development Board with an IMX8M Mini module and try to setup a SPI connection with an external Slave. I try to connect a SPI slave (ET1100 from Beckhoff) via SPI1 (ecspi2) to the IMX8M mini. The four SPI signals (MOSI, MISO, CLK and CS) are routed from the connector X7 via the level shifter X40 (3,3V <-> 1,8V) to the SPI Slave which is in the 3,3V domain. As the imx8m mini does not support 3,3V I have to levelshift all signals. The signals from the IMX8 (Master) Clock, …

SPI timing between consecutive transfers is more than 150us

Hi, We are in a need to use the SPI of VF61 with a high-transfer rate. Unfortunatelly, we are facing an issue in were the timing between consecutive SPI Transfers is too high for our requirements. In our tests, using a direct SPI access in a C program is taking 150us between each SPI transfer. In the picture below, the timing between two SPI transfer is 450us because we are using a delay_usecs of 300us (for tests), but that resulted in a total time-window of 450us (150+300).
