基于XMC_LINK的XMC4800下载电路提示No source available for

首先官网购买了XMC_LINK产品，用于J-link下载程序，用到的软件为DAVE，目前版本是DAVE4.2.8，自己按照10pin-cortex Debug下载电路设计了XMC4800下载电路，但是下载时候出现问题，提示：No source available for "(gdb[2].proc[42000].threadGroup[i1],gdb[2].proc[42000].OSthread[1]).thread[1].frame[0]"
下载过程中的console显示如下：

不知道问题在哪？有用过XMC_LINK的大神能不能给点指点，现在是XMC_LINK直接与XMC4800相连接，
