a. For SPI, 3G version R12.x supports the /dev/sierra_spi device.
3G versions R13.1 and R14 support the /dev/spidev device; however, there is a known issue.
Please follow the Legato guide:
Cat1 version R10.1 supports the /dev/spidev device; however, the spisvc kernel module must
be manually loaded:
See the Customer Release Notes for more details.
CatM version R9.1 supports the /dev/spidev device; however, the spisvc kernel module is not
present and needs to be manually copied to the device.
Note: If you develop an IOT card and use the UART in a hardware loop-back mode by
connecting the transmit and receive signals, do not configure UART2 in Linux Console
mode (AT!MAPUART=16,2).
