Please refer to the 'Figure 58-1. i.MX 6Dual/6Quad SPBA connectivity' of i.mx6DQ Reference Manual. SDMA provide the corresponding app_2_mcu/mcu_2_app and shp_2_mcu/mcu_2_shp script for such two options. So both AIPS and SPBA scripts should keep the same behaviour, the issue only caught in AIPS script sounds not solide. The issue is more likely as the ecspi errata ERR009165(http://www.nxp.com/docs/en/errata/IMX6DQCE.pdf): eCSPI: TXFIFO empty flag glitch can cause the current FIFO transfer to be sent twice So revert commit 'dd4b487b32a3' firstly.
