I'm practicing the bootloader system nowadays. I read the AN2295 application note for building bootload. And, i also download the AN2295 SW for practice.
First, I modify the bootloader_cfg.h to matching the Kinetis L seires. Also, I modify MEMORY size in the AA295_LinkerFile.Icf.
Build is running without problem.
But the problem is when i start the debug, it always stops at the main function or Boot_RsetMCU function.
Except the bootloader_cfg.h file, i didn't touch AN2295 SW file. (I changed baud rate from 115200 to 57600)
I'm using FRDM-KL25Z and Codewarrior 10.3.
Do you have any idea?
I noticed that it caused by Hard Fault.
But i'm not sure what is hard fault and why it occured.
Could you help me?
