Freedom KL25 Bootloade not working

Discussion created by Pavan tmt on Jun 29, 2017

Board i used Freedom KL25 Board and Code warrior 10.7 with your latest code
Debugger i am using is OPENSDA
Steps:-
I change only address specified in your tutorial
m_interrupts (RX) : ORIGIN = 0x00004000, LENGTH = 0x000000C0
m_text (RX) : ORIGIN = 0x000040C0, LENGTH = 0x0001BF40

I increasing debounce delay also to 500msec and protected boot area 0x0000 - 0x3FFF in debugger settings
Used 3.3K for pull up
Connections:-
Push Button one terminal - 3.3V
Push Button another terminal 3.3K pullup resistor one terminal - PTB8
3.3K pullup resistor one terminal - GND
In Debugger mode in Code Warrior With Push Button not pressed go to Application mode and Push Button pressed got to Bootloader mode

In Terminal App
Set it as RTS/CTS +XON and XOFF
1 ms delay

BL status is working perfectly fine but adrress is coming different
CMD>BL
App Flash : 0x00004000..0x0001FFFF
@0x00004000: 0x20003000 0x000052B1

BL erase and BL load s19
CMD>Er

Please guide me how to get it done and Your Blink_LED.s19 is not working.

I generate s19 file of Frredom_LED code by selecting After Post Build Process "arm-none-eabi-objcopy -O srec "${ProjDirPath}/FLASH/${ProjName}.${BuildArtifactFileExt}" "${ProjName}.s19""

Similarly i want to build Bootloader for KEA128 and K20(72Mhz) Board. If you have any ideas how to build a bootloader for these two boards please guide me.
