To Whom It May Concern: My name is Dan DaCosta and I am working with Rockwell on a smaccms transition project referred to as HTA. The manifest associated with this project can be found here: https://github.com/smaccm/hta This manifest is mostly concerned with targeting the cma34cr board. When building images using a Fedora 26 based OS that relies on gcc 7 the following fault occurs: FAULT HANDLER: data fault from vm.ethdriver.control (ID 0x202) on address

The config I am primarily interested in is named "cma34cr_centos_defconfig" but I seem to have similar problems for all the cma34cr defconfigs. I was successful at building working images when I switched to building on Ubuntu 16.04 LTS. This distribution version uses gcc 5.4. Thanks! Dan DaCosta
