SPI Master Mode Compatibility for Verdin iMX8M Plus
Yes, the Verdin iMX8M Plus modules support SPI master mode(1)(2)(3). In the Verdin module standard, only the SPI master mode is specified(3)(4). The slave mode might not be compatible with other modules(3)(4).
Available SPI Interfaces
The i.MX 8MP SoC features a total of three SPI interfaces, called Enhanced Configurable Serial Peripheral Interface (ECSPI) in the NXP documentation(3)(4):
- “Always Compatible” SPI Interface - Available on all Verdin modules(1)(2)
- Two additional SPI interfaces - Available as alternate functions of other interface pins(3)(4)
SPI Performance Specifications
The SPI ports operate at up to 60 Mbps in master write mode and up to 30 Mbps in master read mode for the “Always Compatible” instance(3)(4). Some other instances have reduced maximum operation frequency(3)(4).
Pin Configuration for Always Compatible SPI
| SODIMM Pin | Signal Name | i.MX 8MP Function | Description |
|---|---|---|---|
| 200 | SPI_1_MOSI | ECSPI1_MOSI | Master Output, Slave Input |
| 198 | SPI_1_MISO | ECSPI1_MISO | Master Input, Slave Output |
| 202 | SPI_1_CS | ECSPI1_SS0 | Slave Select |
| 196 | SPI_1_CLK | ECSPI1_SCLK | Serial Clock |
Device Node Access
For user-space access, the SPI interface is available as /dev/verdin-spi-cs0(1). You can verify available SPI devices using:
# ls -l /dev/verdin-spi*
The ports provide full-duplex, synchronous, serial communication between the Verdin module and internal or external peripheral devices(3)(4).
