In the Teensy 3 code currently, specifically file mk20dx128.c , there is a line
this is causing problems when it is used with a bootloader I wrote, because "user app" has its own vector table, my bootloader sets SCB_VTOR to the new location before launching the "user app", but the "user app" is also written with Teensy 3's startup code and thus the above line of code breaks the "user app" as it reverts the change that my bootloader made.
I think a better way of writing that line would be
Which will set the correct vector table location while respecting the actual placement as defined by the linker script.
Code:
SCB_VTOR = 0; // use vector table in flashthis is causing problems when it is used with a bootloader I wrote, because "user app" has its own vector table, my bootloader sets SCB_VTOR to the new location before launching the "user app", but the "user app" is also written with Teensy 3's startup code and thus the above line of code breaks the "user app" as it reverts the change that my bootloader made.
I think a better way of writing that line would be
Code:
SCB_VTOR = (uint32_t)(&gVectors[0]); // set vector table, supports bootloadersWhich will set the correct vector table location while respecting the actual placement as defined by the linker script.
