Hi, I'm using the FRDM-KW41Z with a KW41Z on it. I'm trying to use the ARM GCC toolchain, but I could not find the linker script (.ld) file for the chip. Using the startup code (startup_MKW41Z4.S), I got errors related to undefined reference to '__data_start__' and '__data_end__', which should be defined in the .ld file. I saw files that seemed to be published by NXP online (eg. MKW41Z512xxx4_flash.ld on GitHub ), but it doesn't seem to be in the SDK anymore?
You can find some linker files in the projects that might help you as well, unfortunately, the GitHub link you are mentioning does not seem to be from NXP, they might be using the MKW41Z but it does not appear to be an official NXP site.
