xscope on XVF3500

[paul.yuan]

The chip used in my xmos development board is xvf3500;
But: no any log output when running xrun --xscope app.xe.
Please help me analyze what's going on.

the app's makefile is as follows:
XCC_FLAGS = -DFLASH_MAX_UPGRADE_SIZE=128*1024 -fcomment-asm -Xmapper --map -Xmapper MAPFILE -Wall -O2 -report -lquadflash -fsubword-select -save-temps -g -fxscope -DXSCOPE -DXUD_SERIES_SUPPORT=4 -march=xs2a -DUSB_TILE=tile[1] -DQUAD_SPI_FLASH=1

the app's config.xscope is as follows:
<xSCOPEconfig ioMode="basic" enabled="true">
</xSCOPEconfig>

the app's xn file is as follow;
