K20FX512 LCF Alignment issue

davidschroeder — Mon, 16 Sep 2013 16:34:02 GMT

I have an application for the K20FX512 Kinetis processor that runs fine when debugging, however when I try to "Flash File To Target" via a J-Link jtag (KwikStik) I receive errors such as the following:

Downloading 0x00000049 bytes to be programmed at 0x00030034

Executing program ....

Error: Program failed. Flash driver reports the following error(s): Chip reported error during program. Please check that the sector you are programming is erased.

Error: Program failed. Flash driver reports the following error(s): Chip reported error during program. Please check that the sec tor you are programming is erased

In looking into this I realized that it always fails on an address that is 4 byte aligned, but not 8 byte aligned. As the flash in K20FX requires 8 byte alignment I modified the PE generated lcf file to require 8 byte alignment. This resolves the issue.

My question is, is this the correct solution, or is there a setting in the hardware connection configuration I should be changing? If this is the correct solution, is there a way to prevent PE from overwriting the modified LCF?

Thanks,

Hello,

you can disable generation of linker file on Build options tab in CPU component. Details attached. Regarding to the issue - could you please post here ProcessorExpert.pe file from your project in order to reproduce it on our side?

I've been working on other projects and am just getting back to this one. Like I said in the original post, it works if I change the alignment to 8 bytes. I've attached the pe file.

Thanks,
