Hello this may be considered to be a duplicate thread but I felt that this forum fits my question better. I am currently working with a custom board and as of right now I am only getting code 10 and I have been to the site but I'm not quite sure I understand what it means by "Serial Number Already Assigned". I currently have no flash chip populated on my board and I would expect to get code 3 but I have not gotten this code only code 10. Any help would be greatly appreciated.
