GUI Flash Tools fails by trying to write BSS Segments

Hi

 

there's a strange error when using the GUI Flash Too inside MCUxpresso. It looks like it tries to flash BSS segments to the RAM address which obviously fails. Below there's a log showing these errors for internal RAM BSS segments (at 0x202000E8) for IMXRT1064 as well for board SDRAM (0x80000040). I'm using the EVK board and using the managed linker script.

 

When I debug the program it works fine, however I saw also that it also gdb target downloads these BSS segments which takes a lot of time and is a bit strange, since they are initialized at startup. No need for target downloading them.

 

I've also attached the generated linker script. The BSS section in question here are from .bss_RAM3 and .bss_RAM4 in the script.

 

Any help is welcome!

 

Best

Rolf
