bootloader and firmware
Hello, I download the CMSIS DAP sourcecode from the mbedmicro on the github. Then I compiled the mdk project(CMSIS-DAP\bootloader\mdk\k20dx128\k20dx128_bootloader.uvproj) and upload it to my mk20 chip, and the bootloader can run.Then I compiled the mdk project(CMSIS-DAP\interface\mdk\k20dx128\k20dx128_interface.uvproj) and get the binar file(k20dx128_kl25z_if.bin).So I run the bootloader and copy this binary file to the MSD. But when I cycle the power,nothing happen,that is,no MSD.So,what can I do?If I just upload binary file,the firmware also can run,but the bootloader can't run. So,what can I do? I must run the concat.py to merge the bootloader and firmware? But I always get the error 2 such as follows: But I configue the settings.py file. Please give me some advice,thank you!
