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!!

  • @Silly Sausage,
    you know, i really do come across as a pain, thank you for pointing that out,

    0xFFFF0000 is the start of arm local ram in the am1707 device-dependent memory map, so it was a miscommunication that i should have tried to clear up instead of posting a cryptic "you are wrong"

    i should really look into this stuff first before posting
