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?
