debugging "blinky" for MPU

So close yet so far...

Hardware: TI AM1707 EVM - ARM926EJ-S microprocessor (not MCU, so not officially supported in the device database)

Debugger: Segger J-Link

Application: GNU compiler toolchain + working LED code

When loaded with J-Link + GDB, the LEDs light up correctly

When loaded by J-Link + uVision, the debugger SEEMS to give me access to the board, but the application doesn't run correctly (starts near 0xFFFF0000, which is on-chip local ram)...

Am I missing something totally basic here? Any help would be greatly appreciated!!

  • is this really the normal workflow for this $5000 compiler??

    no, it is not, I, and all I know, do not have any such problems.

    Bring up the IDE, load the project [change device} [change debugger settings] and GO

    had to be issued manually and then set PC to 0xc1080000
    sounds as if you have selected the wrong device.
