SPI usability with GNSS on EC200U-EU AA

IoT Modules LTE Standard Module
1

Hello,
I have a Quectel EC200U-EU AA module and I need to use external SPI flash while the GNSS function is enabled.

I know the primary SPI (pins 37–40) is disabled when GNSS is active.
I see that pins 24–27, 13, 135 can be multiplexed as a secondary SPI according to the QuecOpen Hardware Design V1.0.

My questions:

  1. Can I use the alternate SPI (pins 24–27) for an external flash while GNSS is active on this variant?
  2. Are there any firmware restrictions for EC200U-EU AA that prevent the alternate SPI from working when GNSS is enabled?
  3. Any recommended examples or demos to test SPI with GNSS active?

Thank you for your guidance!

  1. Can I use the alternate SPI (pins 24–27) for an external flash while GNSS is active on this variant?
    Yes, you can use SPI2(pins 24-27). GNSS uses SPI1 port.
  2. Are there any firmware restrictions for EC200U-EU AA that prevent the alternate SPI from working when GNSS is enabled?
    No.
  3. Any recommended examples or demos to test SPI with GNSS active?
    Please refer to the example code in SDK to enable external flash.
