Example MikroBus Rotary on the iMX6U-112
This is a guide to the MikroBus Rotary Demo on the iMX6U-112 IIoT Development Kit.
| NOTE |
| Do to a design flaw in the MikroBus Rotary B Click, the card does not allow another SPI device to be present on the SPI Bus. The SoM-IMX6U uses the SPI Bus and the presence of MikroBus Rotary B Card prohibits the SOM from booting. To alleviate this issue, the pin labeled “SDO” must be cut and jumpers JB5 and JB6 on the Dev Kit Carrier Board (SoM-112) must be set to 3P3 (see figures below) |

make - CMake
Setup
If you haven't already, please review the "getting started" page for the DEV-IOT6U. EMAC_OE_SDK will need to be installed and serial and network connections will need to be established between the developer machine and the target device. See the Serial Connections or Network Connections page for more information on how to connect to the target EMAC product using a serial port or Ethernet connection.
- Download this file
- Open a terminal and minicom/putty into the board
- get the ip address
- second terminal
- use EMAC OE SDK guide for host compiling
Usage and Behavior
