Mark,
Just to report back. After I've pulled down new version, the cross-compilation process works and I'm actually able to run bootloader on frdm-k22f board.
I've reviewed ?Tasker – Serial Loader User’s Guide in order to compile bootloader as specified in the in section 4, where SREC mode is enabled and menu is available via UART, but compilation fails once SERIAL_INTERFACE is uncommented with the following error:
unresolved external symbol _fnPerformBlankCheck referenced in function _fnApplication
but if SERIAL_INTERFACE and KBOOT_LOADER are uncommented, then compilation runs fine and I'm able to access target via KinetisFlashTool. What additional settings I need to adjust to get the same functionality as described in section 4?
The same applies if I attempt to enable, for instance, USB_INTERFACE and USE_USB_CDC which fails on
unresolved external symbol _fnPerformBlankCheck referenced in function _fnApplication
or USB_INTERFACE and USB_MSD_DEVICE_LOADER
unresolved external symbol _fnAddSREC_file referenced in function _fnLoadTerminate
