Bootloader AN2295

I ported the AN2295 bootloder to my chip (MK10DN512).

The bootloder linker configured

define symbol __ICFEDIT_region_ROM_start__      = 0x00000410;
define symbol __ICFEDIT_region_ROM_end__        = 0x00000AFF;
define symbol __ICFEDIT_region_RAM_start__      = 0x1fffff00;
define symbol __ICFEDIT_region_RAM_end__        = 0x1fffffff;
define symbol __ICFEDIT_region_RAM1_start__     = 0x20000000;
define symbol __ICFEDIT_region_RAM1_end__       = 0x200001ff;
define symbol IntVectTable_start__              = 0x00000000;
define symbol IntVectTable_end__                = 0x0000003f;
define symbol FlashConfig_start__               = 0x00000400;
define symbol FlashConfig_end__                 = 0x0000040f;

So in main project I do

define symbol __ICFEDIT_region_ROM_start__ = 0x00000B00;
define symbol __ICFEDIT_region_ROM_end__ = 0x00080000; //512K

And build to get s19 file.

I open Universal Bootlosder utility and press Connect.

I get the following message

How should I configure the main project?

Hi Andrey

An application needs to be located where the boot loader expects to find it - therefore you need to see where that is in the boot loader configuration.

0xb00 would not be a valid address since it is in the first sector of the Flash (where the boot loader is) and so would not be possible.

Your application will also have a reset vector which will need to be located correctly - looking at the warning that you have I expect that you still have this at 0x0000000 which would be invalid since the boot loader is there (hence the overlap).
