There is a very quick way to find out which line cause the crash in logcat, Generally, if some native service crashes, look in the crash log in logcat like this: I/DEBUG ( 2253): *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** I/DEBUG ( 2253): Build fingerprint: 'freescale/sabresd_6dq/sabresd_6dq:4.0.4/R13.3-rc3/eng.b18293.20120710.124535:user/test-keys' I/DEBUG ( 2253): pid: 3043, tid: 3080 >>> /system/bin/mediaserver <<< I/DEBUG ( 2253): signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr deadbaad I/DEBUG ( 2253): r0 deadbaad r1 00000001 r2 a0000000 r3 00000000 I/DEBUG ( 2253): r4 00000000 r5 00000027 r6 00bfd370 r7 40c1ef18 I/DEBUG ( 2253): r8 00004349 r9 00000000 10 000003f5 fp 00000000 I/DEBUG ( 2253): ip ffffffff sp 418876a0 lr 400ff1b5 pc 400fb91c cpsr 60000030 I/DEBUG   ( 2253):  ip ffffffff  sp 418876a0  lr 400ff1b5  pc 400fb91c  cpsr 60000030 We can see it’s possibly related to some code that we debugged, but don’t know exactly where or which line of code, Android has a tool to convert this log to a more precise log.

i.MX31 - 3 Stack There are two boot modes for IMX31PDK. In Internal Boot mode, the processor will execute an address from internal memory, and in External Boot mode the processor will execute an address from a external memory properly configured. This modes can be configured setting the values of dip switch SW5-SW10 shown in image below. Debug board. Top view. External Boot from Flash In this mode, the processor will execute an address into a external flash (NAND). If there is a bootloader saved in the right place in flash, it will be executed and the system will start. If there are a kernel image and a root file system saved configured, the operational system will start. The values for the IMX31PDK dip switches programming the boot sequence are show in table below.

Certify the version of bootloader When updating the BSP files of a system, it's recommended to rewrite a right version of bootloader in the target. Connect platform to PC To connect the 3-Stack platform to your host PC: Connect one end of an RS-232 serial cable (included in the kit) to a serial port connector (CON4) on the Debug board and connect the other end to a COM port on the host PC. Configure SW4-1 to ON. Make sure that SW4-8 is ON, to supply power to all three boards. Configure SW4-2 to OFF. Confirm that the Bootstrap switches (SW5–SW10) are set for external NAND boot (see more here) Connect the regulated 5V power supply to the appropriate power adapter. Plug the power adapter into an electrical outlet and the 5V line connector into the J2 (5V POWER JACK) connector on the Debug board. Start a serial console application on your host PC with the following configuration: Baud Rate 115200 Data Bits 8 Parity None Stop Bits 1 Flow Control None On the Debug board, switch the power switch (S4) to 1. The OS image pre-loaded in the 3-Stack board will boot and the debug messages from the bootloader should now appear on the serial console application on your PC See Also For a setting without the Debug board see Demonstration Platform.
