Hi Joel

> Do you have local changes which are not in RTEMS main?

Yes. The BSP\_ config parameters and various simple console fixes for the TI bsps.

* MR: https://gitlab.rtems.org/rtems/rtos/rtems/-/merge_requests/1094, pending approval to be merged into main.

> What's different between the default configuration of the lm3s6965_qemu BSP and what you have above?

>From `linkcmds.lm3s6965_qemu` linker script on main:

```dsconfig
MEMORY {
	RAM_INT (AIW) : ORIGIN = 0x20000000, LENGTH = 16M
	ROM_INT (RX)  : ORIGIN = 0x00000000, LENGTH = 64M
}
```

In the default configuration, applications perform MMIO writes and reads at addresses that are outside the the QEMU lm3s6965evb machine memory map. When run with `-d guest_errors`, the applications fail with invalid memory reads/writes.

* Initial post in the users forum flagging this problem: https://users.rtems.org/t/arm-lm3s6965-qemu-debugging-hello-exe-datasheet-differences/561
