SOC FPGA的 JTAG烧写失败原因 [复制链接]

 用的是micro semi 的smartfusion2系列 soc芯片，在用libero烧写程序时出现报错问题，显示错误信息好像是电压问题，有个警告是Warning: programmer '95364' : Vpump has been selected on programmer AND an externally provided Vpump has also been detected. Using externally provided Vpump voltage source.  错误是Error: programmer '95364' : device 'M2S010' : Executing action PROGRAM FAILED, EXIT -22, refer to FlashPro online help for details. 看了-22的错误详细内容显示Failed to program pass key.   可能原因是：Unstable VPUMP voltage level.
Unstable VCC
Unstable VCC_OSC (Fusion only)Unstable VCC_ROSC voltage level (SmartFusion only)
Signal integrity issues on JTAG pins.




求问各路大神怎么排查问题

一锅年糕

请问这个问题解决了吗，我也遇到了相同的情况
