Ok so after reading quite a bit of the dev board manual I found this.
When attempt to download outside of the user program address, an “E” is printed and the
line is ignored. This usually happened when CONFIG registers are programmed.
Download cannot modify CONFIG registers.
This says why Im getting the E’s when transferring my HEX file but I dont knowwhat it means or how to fix it. The manual doesnt go into detail about it.
Thanks
