Mark, et al,
I am writing firmware for a KL27 with embedded ROM bootloader using KDS.
When writing directly directly into the KL27 using my SEGGER JLINK I using the build configuration uTaskerV1.4_FLASH. Everything works fine.
When using the ROM bootloader, I would think the build configuration changes to uTaskerV1.4_BM_FLASH. When I try to use the ROM bootloader with the newly created BM_FLASH image everything seems to load fine but the KL27 goes into a watchdog-type reset loop upon startup.
Again, when I load using the uTasker1.4_FLASH build configuration using my SEGGER JLINK debugger everything works fine.
Any ideas?
Thanks.

Hi Phil
When using the KL27's ROM Loader you can load the uTaskerV1.4_FLASH target with the KBOOT utility. The uTaskerV1.4_BM_FLASH target has an offset which the ROM loader doesn't use.
