====== MBa7x DIP switch settings ====== ===== Boot Device Selection (S1, S2, S3 & S4) ===== To select the desired boot medium set the DIP switches S2, S3, S4 and S1 accordingly. To enable boot device selection BOOT_MODE has to be set to "Internal Boot".\\ This can be done using DIP switch S1 on MBa7x. \\ Switching boot sources is only possible if the BOOT_MODE fuses are not programmed. If configured for "Boot from eFuses" but fuses are not programmed, the boot loader will not be able to determine the boot source. ^ BOOT_MODE ^ S1-1 ^ S1-2 ^ | Boot from eFuses | 0 | 0 | | Serial Downloader | 0 | 1 | | Internal Boot | 1 | 0 | \\ The following boot modes of the i.MX7 can be selected by the DIP switches S1, S2, S3 and S4 on the MBa7x: [size=150%]**S1**[/size] {{ :en:dip_2_10.png?nolink&85 |}} [size=150%]**S2**[/size] {{ :en:dip_8_01001000.png?nolink&270 |}} [size=150%]**S3**[/size] {{ :en:dip_8_00001000.png?nolink&270 |}} [size=150%]**S4**[/size] {{ :en:dip_4_0000.png?nolink&140 |}} [size=150%]**S1**[/size] {{ :en:dip_2_10.png?nolink&85 |}} [size=150%]**S2**[/size] {{ :en:dip_8_00000100.png?nolink&270 |}} [size=150%]**S3**[/size] {{ :en:dip_8_00010100.png?nolink&270 |}} [size=150%]**S4**[/size] {{ :en:dip_4_0000.png?nolink&140 |}} [size=150%]**S1**[/size] {{ :en:dip_2_10.png?nolink&85 |}} [size=150%]**S2**[/size] {{ :en:dip_8_00000000.png?nolink&270 |}} [size=150%]**S3**[/size] {{ :en:dip_8_00000010.png?nolink&270 |}} [size=150%]**S4**[/size] {{ :en:dip_4_0000.png?nolink&140 |}} ---- ===== Functional DIP Switches ===== DIP-Switch settings for CAN and RS485.
