MK20DX256VLL7 with Codewarrios Flash issue

felixgottwald — Thu, 10 Aug 2017 10:58:25 GMT

Hi,

I`am using MK20DX256VLL7 with J-Link Edu and Codewarrior 10.7.

Debugging works fine but if I try to flash the device, get the output shown below.

I´ve tried all proposed solution from other tickets, without success.

For me, two things in the output of the flash tool are confusing. Why it says that the hex file is of 0 Byte size. This is not true. The debugging session also uses this file, successfully.

The second thing is about the resticted memory area. In this adress range, the controller has some NMI stuff in use but NMI is disabled in ProcessorExpert.

If I try to flash the elf-File with SEGGER Tools results in exactly the same behaviour. It seems like the code memory is allocated to RAM but in the build options everthing is linked to internal flash.

I´ve no idea, what do, to get the programmer running with this controller. And would be very greatful for your help.

Thank you and regards
