一、找不到设备

出现报错： [Labtools 27-2269] No devices detected on target
localhost:3121xilinx_ tiXin/000000000000O
Check cable connectivity and that the target board is powered up then
use the disconnect_ hw_ server and connect hw_ server to re-register this hardware
target.

板子上的jtag是有6根线引出来的 包括TCK TDO TMS TDI GND VREF六根线引出 和xilinx烧写器六个端口连接 注意看这几个连的对不对 连正确了就可以找到设备了

二、找到设备 但是无法烧录

ERROR: [Labtools 27-3303] Incorrect bitstream assigned to
device. Bitfile is incompatible for this device.
ERROR: [Labtools 27-3165] End of startup status: LOW
ERROR: [Common 17-39] 'program_ hw_ devices' failed due to
earlier errors.

没法烧录最先排查芯片型号选错 要看板子上FPGA芯片型号
